The KBS Fuel Tank Sealer System removes rust and restores the inside of your tank to new condition

Rust and varnish in a fuel tank can cause problems. First, rust can create small holes that fuel can leak out of, and it can also weaken welds, creating a fire hazard. Problems can arise on vehicles with fuel pumps in the tank as fine rust particles can get through the strainer in the pump mount and into the pump and cause damage. In addition, rust particles can accumulate in fuel filters, which restricts fuel flow, meaning the vehicle gets enough fuel when idling, but then not enough when accelerating. Particles can also clog injectors and carburetors. Rust in fuel tanks is a bigger problem today than it was in the past because today’s ethanol-gasoline blends are more corrosive than the ethanol-free gasolines of the past.

If your fuel tank has rust, there are two ways to fix the problem: replace the tank with a new one, or take steps to clean the inside of the tank, remove the rust, and seal the inside with a fuel tank sealant. Replacing the fuel tank can be very expensive, especially on some classic cars where the tanks are very expensive. And even a new tank that hasn’t been sealed will start to rust and cause the same problems. If you have a diesel vehicle, diesel sludge contamination is another fuel tank issue to consider. Diesel sludge is an algae-like substance that adheres to the tank surface or fuel-water interface. The sludge settles at the bottom of a fuel tank and can clog filters when the vehicle is refueled. A good tank cleaning will help with this problem.

KBS Coatings offers the easy-to-use Tank Sealer System as an effective, high-quality and economical solution for cleaning, derusting and sealing your fuel tank. The KBS tank sealing system stops rust and forms a tough, fuel impermeable coating while sealing small holes and welds. Whatever your tank contains will never touch the inside walls of your tank again.

The KBS Tank Sealer System consists of three components. KBS Klean, RustBlast and Gold Standard tank sealers.

KBS Klean is a powerful cleaner that deeply penetrates and removes dirt and paint without leaving a harmful residue or emitting toxic fumes. KBS Klean is a highly concentrated, water-based, biodegradable formula that’s insanely strong and a great alternative to flammable solvents and hazardous chemicals.

KBS Klean is designed to be diluted with water and a full dilution is 1 part water (hot water works best) to 1 part KBS Klean. Pour the bottle and water into the tank, put in some metal objects like nuts and bolts to act as stirrers, and shake the tank up. Let it soak for 45 minutes, then rinse with water until no more foam comes out. You can repeat as many times as necessary.

The next step is RustBlast, a strong rust remover, zinc phosphate pre-primer and metal etchant. RustBlast effectively breaks rust, corrosion, metal oxides and tarnish from the inside of the tank. It etches the surface leaving a zinc phosphate layer to ensure a strong bond with the tank sealer. The zinc protects against rust film if the tank sealer cannot be applied immediately.

When working with RustBlast, leave the agitators used in the previous step in the tank. Shake the tank thoroughly and allow the RustBlast to sit for about 45 minutes, rotating the tank about every ten minutes to etch all surfaces. Then pour the RustBlast into a container, but don’t discard it yet in case the process needs to be repeated. Rinse the tank well with water and check if all the rust is gone. If not, repeat the process. After the rust has been removed, the tank must be thoroughly dried. It is best to use a heat gun or hair dryer to ensure it is completely dry. Don’t forget to remove the agitators!

The grand finale is the application of Gold Standard Tank Sealer, a superior, ready-to-use, one-part fuel tank sealer formulated for coating the inside of metal, aluminum and fiberglass tanks. Gold Standard Tank Sealer is an easy-to-use, disposable coating that cures to form a tough, fuel-tight seal. The entire tank including pinholes and welds is permanently sealed to prevent the return of rust and corrosion and clogged carburetors.

After pouring the tank sealer, leave it there for 45-60 minutes. Roll the tank frequently to ensure it covers all interior surfaces and seams. Make sure all remaining fuel tank sealant is completely drained from the tank as you don’t want to leave puddles. The tank can be supported at any time and left to drain. It is very important that the sealant is allowed to cure for four days before adding fuel.

Rust and varnish buildup in fuel tanks is a big problem. The KBS Tank Sealer System is an excellent solution.

In today’s article I will talk about the auxiliary fuel tank and whether it is worth buying or not. The biggest concern when we are in the trucking business is fuel and we are always trying to find a way to reduce fuel costs.

In addition to having the right truck, to make transportation truly successful, you need to be careful about spending and find a way to cut down on the unnecessary expenses.

We all try a few things to reduce fuel consumption, from preparing routes with the route optimizer to using fuel cards to control fuel spending or to get lower fuel prices at certain gas stations.

The latest fueling control practice is the use of fuel management devices, which provide us with specific information about the amount of fuel our truck drivers are adding to the fuel tank, thereby enabling us to prevent fuel fraud and fuel misuse.

I’ll show you the pros and cons of an extra fuel tank and leave that decision up to you.

In which category is your truck?

1. Class 8 trucks

Class 8 fuel tanks naturally have a few sizes with different capacities. On average, the standard fuel tank can hold 125 to 300 gallons of fuel and you have 2 fuel tanks. So let’s say you have two fuel tanks on your truck with 125 fuel capacities giving 250 gallons of fuel that you can use.

On the other hand, you install an additional fuel tank with 50 gallons of additional fuel capacity. There are many gas stations on your route where you can stop and refuel the truck, and I am talking about gas stations where you can use your fuel card to refuel cheaper.

Send me the PDF

So if you can stop almost anywhere you don’t need to have a spare tank because you can buy fuel every 20 miles, say. If you can do that, what would be the point of having an extra fuel tank?

You get what I mean, don’t you?

2. Medium trucks

However, this applies to the trucks that fall into the category of Class 8 trucks. However, if you drive medium-duty trucks where the fuel tank has a smaller capacity, you may consider purchasing an additional fuel tank, although you should consider the range of driving and the ability to refuel your existing fuel tank along the routes you drive.

Source: www.thefuelbox.com

However, if you have to travel a long distance with few gas stations or are unfamiliar with the fuel prices on that route, an extra fuel tank is a good choice for you. It will eliminate the possibility of being stacked in the middle of nowhere or being forced to buy an expensive fuel.

One way or another, if your existing fuel tank doesn’t have enough capacity, the extra fuel tank in your truck bed is like a spare tire; It will be there if you need it. For medium-duty trucks, an extra fuel tank can be worth the upfront cost because you can choose stations where the fuel is cheaper.

When preparing to purchase an additional fuel tank, check fuel prices

As I mentioned earlier, the purpose of the extra fuel tank is to have extra fuel available to extend your range and choice of refueling when prices are lower. That’s fine when prices are high, so the difference from gas station to gas station can be huge and the savings are noticeable.

Source: www.autoevolution.com

But in the period when the cost of fuel is very low and the savings are not noticeable, there is no need to invest in the additional fuel tanks.

The aim is to save money with the additional tank and not cause additional costs without good reason.

Advantages and disadvantages of the auxiliary fuel tank

Whether or not you buy an extra fuel tank is an individual matter and depends on your driving habits or the routes you travel. Anyway, I want to list the general pros and cons of auxiliary fuel tanks

Source: www.otralogistics.com

Advantages:

You can buy fuel on your schedule – buying fuel when you want and not when you’re forced is a huge benefit when you’re out on the open road. It’s your choice if you have an extra fuel tank and you can create your own schedule without having to comply with highway prices and rules. You can save money – The extra fuel tanks can save you money when you drive through the route with high prices. So if you drive around this area without this fuel tank, you will have to buy fuel at these gas stations regardless of the fuel price. But if you have the extra fuel in the extra fuel tank, you can complete the route without stopping at a gas station. The additional fuel tank extends your range – you can drive more kilometers between fill-ups. So you can drive many more kilometers without stopping at a gas station. By extending the mileage, you save time.

Disadvantages:

Highest on this list are federal regulations that must be followed if you have an extra fuel tank. If you decide to fit an extra fuel tank, you need to make sure it is leak and drop tested. These FMCSA regulations are designed to ensure fuel does not leave the tank in the event of a disaster.

Also, it must be certified and properly marked with:

The month and year of manufacture

To have the manufacturer’s name

Being able to identify the place of manufacture

Maximum fuel tank size is 119 gallons – if larger than that, it is classified as cargo and subject to hazardous material regulations

Fuel line regulations must also be covered

Extra weight on the truck – the extra weight of the fuel can result in higher fuel consumption, so you end up with no savings even if you invest in an extra fuel tank. Additional Costs for Proper Installation – It’s not just the purchase of an additional fuel tank, you must take your truck to a professional servicer to have the installation per Federal Motor Carrier Safety Administration (FMCSA) or Department of Transportation ( DOT) to perform. If the auxiliary fuel tank is not installed according to these rules, there is a high probability that you will receive a penalty from roadside inspection. Additional Maintenance – Auxiliary fuel tanks must be maintained in the same manner as the manufacturer’s fuel tank. When it comes to maintenance, you need to be very careful, because an unmaintained auxiliary tank is just bad news that can affect your wallet. Additional Costs – The cost of the additional fuel tank can vary from:

brand to brand

specifications

material

capacity

Basically, the price of auxiliary fuel tanks varies from $400 to more than $1,500. Also, if you need custom auxiliary fuel tanks with additional specifications or additional equipment, the prices can get very high.

The fuel tank is responsible for holding the gasoline or diesel that powers the vehicle. Of course this job is very important. A leaking or defective fuel tank is not only extremely annoying, but also downright dangerous. Gas vapor is a major contributor to smog and is easily ignited in the right concentration. LPG is flammable (and should be cleaned up after every spill), but it’s still much more stable than vaporized gas. For these reasons, fuel tanks must be reliable and have a significant lifespan. Modern cars have fuel tanks made from lightweight plastic materials. What a tank is made of is a big factor in fuel tank life.

What are fuel tanks made of?

Automobile manufacturers have used coated steel fuel tanks in vehicles since the early days of automobile production. A tin-lead coating prevents corrosion and ensures years of tank life. For applications where weight is a concern, aluminum is a good alternative to steel. In recent decades, the use of HDPE (high density polyethylene) has grown in popularity.

HDPE is a type of plastic that is strong, durable, and resistant enough to impact and temperature extremes to be used for such an important part. Because HDPE is so malleable and flexible when warm, it can be molded into very complex shapes to fit perfectly anywhere there is space under the car. This means manufacturers can place the tank in a location that is more resistant to punctures in the event of an accident. Because the tank has no seams, there are no weak points to break when the tank flexes.

How long does each type last?

Manufacturers aim for a minimum service life of 10 years for metal fuel tanks. Now there will be some variation as to how long each material might last individually, either coated steel or aluminum, but unless the tank suffers external damage it will last at least a decade. Some tanks last for decades, so metal tanks only need to be replaced if they are damaged or badly corroded.

HDPE fuel tanks can potentially last a very long time because the plastic is not prone to corrosion and can easily bend under pressure. HDPE itself is specially designed to contain harsh chemicals and is used to contain chemicals that are significantly more dangerous than gasoline, so tanks made from HDPE are overengineered in this regard. In terms of durability, they last at least 10 years, with the average being above that. HDPE’s worst enemy is shock and extreme temperatures, but the material is durable enough to withstand average wear and tear.

Just like vehicles and equipment, underground storage tanks (USTs) have a lifespan of their own and will eventually need to be replaced. On average, tanks can last around 25 years. However, when the tanks are approaching “retirement age” and showing signs of corrosion and rust, it is probably time to buy new tanks.

Replacing USTs can require significant investments in terms of equipment, construction costs and downtime. It is also a process that should be carefully followed before signing an order, during installation and after installation. With a little legwork and due diligence on your part in these areas, you can help ensure:

The lowest total cost of ownership over the life of the equipment

Safe practices are followed during UST installation

UST compliance management is effective

Let’s take a closer look.

Before signing an order

Take a look at the regulations

Identifying VAT regulations (including pending regulations) that mandate equipment requirements or involve recurring labor and maintenance costs helps ensure compliance. This will also give you a better idea of ​​the total cost of ownership. Discuss applicable regulations with your supplier as well, so they can offer cost-effective product solutions that meet regulatory requirements.

Consider materials and tank shape

Choosing the right tank can prevent tank failure and future complications. USTs are made of either fiberglass or steel. Steel is stronger and a good choice when you have heavy equipment on site or are experiencing severe weather changes that can cause soil saturation and fractures. In general, fiberglass can withstand corrosion in all climates. Flat-ended steel tanks take up less space than domed-ended fiberglass tanks and are typically less expensive to install.

Invest in available products

Investing in products that protect against water ingress and leaks is money well spent. It will help reduce maintenance and contamination issues in the future. Discussing prevention solutions that are compatible with your USTs with your supplier will help extend the life of UST components and protect tank integrity.

Identify potential expenses

The UST installation requires several purchases in addition to the tank. Asking your supplier for a list of potential costs for different UST types will give you a clearer picture of your total investment and tank lifetime value.

During the installation

Inspect and test tanks

Photograph and document tanks upon arrival. Be sure to check for defects. Conduct testing procedures and immediately report any issues to your supplier to ensure the warranty is not voided.

Proper ballast tanks

Ballast tanks with water, not fuel. Once fuel is pumped into the tank, the tank is subject to VAT regulations and must be insured.

Investigate the dig site with contractors

Make sure the contractors dug the correct size hole. If it is too shallow and tanks are in an area that is traveled by vehicles or heavy equipment, the tanks may not be protected from the overhead weight. If the hole has an unnecessary slope, more backfill is required, which means more expense. Also make sure that the correct material is used to fill the tank according to the manufacturer’s specifications. Supervise installers during the backfill process to ensure no voids are created.

Create a “birth certificate”

Prior to backfilling the site, document relevant information including the UST serial number, dimensions, burial depth and mooring system. This also serves as a reference for maintenance, upgrades, insurance inquiries and for future property owners.

After installation

follow through

Keep current with maintenance, testing, and inspection procedures to ensure effective compliance management.

Complete certification and financial responsibility requirements

Complete the EPA’s Notification for Underground Storage Tanks form and submit it to the appropriate local or state agency within 30 days of the UST becoming operational.

Keep records demonstrating fuel compatibility

For UST components, you must demonstrate that they are approved by the manufacturer or by a nationally recognized independent testing laboratory for use with the fuel stored in the tank.

Update VAT “Birth Certificates”.

Any maintenance or upgrades that require changes to the equipment should be documented on the “Certificate of Birth”.

Proper chemical storage is an important aspect of operating a plant or facility. To ensure your chemicals are safely stored in polyethylene tanks, you need to choose a tank with the right wall thickness. A fraction of an inch can mean the difference between a tank that lasts for decades and one that fails early.

Here’s what you need to know about determining the right wall thickness for your chemical storage tank.

Factors affecting the walls of your tank

Wall thickness varies from tank to tank based on several factors, all of which play a role, including:

chemical storage

operating temperature of the chemical

Dimensions of the tank

The chemical itself and its operating temperature determine a tank’s specific gravity (SPG) rating. Dense and warm chemicals have a higher specific gravity than lighter, cooler chemicals. Your tank must be rated for the correct specific gravity or it could fail. We manufacture our standard tanks with SPGs of 1.35, 1.65, 1.9 and 2.2.

The SPG and operating temperature of a liquid are directly proportional to the weight and pressure that the chemical exerts on the bottom sidewall of a tank. Customers often ask how thick the wall of a chemical storage tank needs to be in a 1.65 SPG tank. It will vary based on the geometry of the tank and our engineers can work with you to determine what you need.

Tank walls can range from 0.20 inch thick to 2 inches thick or thicker depending on size, dimensions and where the measurements are taken. A 1.65 SPG tank that is very short and shallow will have a thinner wall than a 1.65 SPG tank that is tall and narrow. This is due to the third factor, size dimensions. As the diameter of a tank bottom decreases and the height increases, the pressure on the lower side wall of the tank increases. As a result, you need a thicker wall to handle the extra pressure on the sidewall of the tank.

Calculation of the wall thickness

The calculation for this geometry results from the permissible hoop stress of the building material. The hoop stress is the force exerted on the tank wall from inside the tank. The hoop stress is higher in a tall, small diameter tank because it is measured in pounds per square inch of pressure in that tank.

A six foot diameter tank, containing the same chemical and gallonage as a twelve foot diameter tank, has less surface area on the lower side wall, requiring thicker walls to accommodate the greater hoop stress. We do our calculations and design each tank based on ASTM D 1998-13 standards. For more information, you can download an explanation of the ASTM standard.

Checking the wall thickness

Poly Processing regularly tests our tanks to ensure wall thickness meets ASTM standards and that our tanks can withstand the pressure of the chemicals you store. We take these tests seriously so you can be confident your chemical storage tank will meet or exceed expectations.

Once a tank has been manufactured, we perform impact tests to determine the tank’s impact resistance and to confirm that the tank has been properly cured. We can also perform ultrasonic thickness testing at different locations and heights of the tank sidewall to determine wall thickness in specific areas.

If you have questions about constructing your tank with the right wall thickness, contact one of our chemical storage experts.

Most construction workers cannot weld aluminum or, more accurately, have never attempted to weld aluminum. If so, why would any of them even consider making an aluminum fuel tank? After all, almost anyone can make a usable fiberglass or composite fuel tank.

In fact, many current manufacturers may not have a choice if the tank is designed as an integral part of the composite structure in the aircraft they are building. However, not everyone builds an airplane out of plastic and there are many, many home made designs that allow the designer to express their individuality and give them the opportunity to make and fit whatever type of fuel tank they prefer. I don’t consider the choice of fuel tank construction as a question between aluminum tanks and fiberglass tanks. . . not at all.

Each type of fuel tank design has its own unique qualities that can make one type better suited to a particular aircraft than the other. Since this article is about metal tanks, let’s put them in the spotlight.

Metal tanks, their characteristics and shortcomings

A metal fuel tank is almost always lighter than a fiberglass tank of similar capacity. A weight saving of three pounds or more can often be realized in a larger tank.

Aluminum is a clean, strong, easily machined material that always delivers predictable results. On the other hand, for those of us who haven’t had the opportunity to learn how difficult aluminum is to weld through expert guidance and plenty of practice. Then most of us don’t have the equipment either. . .

Unlike steel, aluminum does not change color when its temperature is raised to the melting point. Also, its lower melting point is reached very suddenly due to its high thermal conductivity. Consequently, the metal suddenly puddles and collapses, leaving a gaping hole, much to the dismay of the unskilled welder when attempting to weld aluminum for the first time.

Another property of aluminum is sure to give the inexperienced welder a hard time. Compared to steel, it has a much higher rate of expansion. This combined with its high thermal conductivity causes aluminum to deform and warp significantly during welding, especially when a continuous seam needs to be welded.

An aluminum tank (as opposed to a fiberglass tank), which is a good conductor of electricity, can easily be grounded to the floor of the aircraft during refueling, eliminating the risk of static electricity build-up. (Have the person doing the refueling attach their ground wire to your exhaust duct.)

You don’t need to know how to weld aluminum to make your own metal tank! And contrary to what you might think, it’s not difficult either. It is relatively easy to completely fabricate a tank in your workshop with no special tools other than a homemade flange bending jig (Figure 1). The outer skins can be cut out and bent into shape with tinships or on a bandsaw. A flange is bent into one of the shells using a home-made flare tool, and then the shells are assembled by pinching the edges together so you can peel the tank off for heliarc welding. Of course, I skipped a few details, but read on.

If you prefer, you can assemble your tank using aircraft rivets, eliminating the need for welding. After all, integral wing tanks on metal aircraft are routinely made this way, so why not just any tank? The riveted seams and rivets must of course be sealed with a fuel-resistant compound.

Note: You may not know this, but Aircraft Spruce and Specialty Co. (and others) sell ready-made metal tanks for a variety of homebuild designs. One of these tanks could be suitable for your plane.

What materials to use?

Fabricate your tanks from .040″ or .050″ weldable aluminum. If the tank is to be fully riveted and no welding is required, aluminum alloy 2024 T3 sheet metal can be used. However, 2024 T3 is not only not weldable, it is also not easily formed except when in its annealed (0) condition. Otherwise, use one of the commonly available weldable aluminum alloys such as 1100, 3003, 5052, or 6061 series aluminum sheet.

I wouldn’t use the soft commercial grade 1100 aluminum as the strength just isn’t there. If using 6061 aluminum it can be heat treated after welding, although this is rarely done by DIYers. Overall, the recommended fuel tank material is 5052, either 1/4 or 1/2 hard aluminum. The designation 5052H32 stands for 1/4 hard aluminum and the designation 5052H34 for 1/2 hard aluminum. The 5052H32 aluminum is very easy to form and is readily available from home build suppliers.

You can make your baffles out of a lighter material than the .040″ or .050″ material used for the tank shells. This is because baffles are usually riveted in place and do not require internal welding. Because of this, you can also use 2024 T3 if you prefer.

The rivets used for the installation of baffles must be of the soft (commercial) type if their heads must be welded over after installation. Use 1/8″ diameter hollow head rivets.

Tanks that are to be fully riveted (no welding) can be closely spaced together using aircraft rivets (AN470AD-4). A distance of about 5/8 inch may be appropriate in most cases, depending on the tank design and thickness of material used. Close spacing for rivets is important to get good tight seams that are leak proof after sealing with a good fuel resistant sealant.

Standard weldable aluminum flanges can be purchased from your preferred supplier, or you can fabricate your own from a large supply of weldable aluminum. The same applies to the filler neck and filler cap. Flush caps connected to a solid aluminum mounting ring are very popular with builders. These filler neck rings can be welded or riveted to the tank to provide a flush, streamlined installation for the gas cap.

Every tank must have some sort of sump, even if it’s no more than an exaggerated dent in the bottom of the tank. The purpose of this depression or sump is to provide a localized low point for water (if any) to settle and be easily drained during a pre-flight inspection.

Tank design considerations

A single large tank is cheaper to manufacture and more efficient than a few smaller tanks. The reason is obvious. Building a small tank takes just as much work as building a larger one. You would also need to make and install a filler neck and cap, vent line, sump, and finger strainer in each tank. In addition, installation tapes, shut-off valves and double piping are required. A multiple fuel tank installation always adds complexity and fuel management issues. As you might have guessed, the weight gain and added expense won’t be welcome either.

Of course, if you need fast long-distance travel, then you will have to put up with the presented disadvantages and proceed to the construction and installation of several tanks.

Should you decide to go for a single tank installation, you will likely feel an overwhelming desire to make that one tank as large as possible. fine . . . but be careful not to make it so big that it doesn’t fit in the allotted space.

If the tank is to be installed in the front of the fuselage, remember that the bottom of the tank must be clear of your feet and also clear of the rudder pedals.

Try to avoid designing an unusually shaped tank as this will only make it more difficult to manufacture and possibly install. Simplicity is the goal. Make your tank out of as few individual pieces of metal as possible. This reduces the number of welds and simplifies assembly. It is possible to make a tank from two large pieces of aluminum as shown in the attached photos. Even a rectangular tank can be made in a similar way if a good paper pattern is worked out first.

Of course, in any case there would need to be a separate piece for the sump and maybe a few more pieces for the baffles. However, the fewer parts used in the manufacture of your tank, the less likely you are to have problems with it.

baffles

The primary function of baffles is to minimize fuel sloshing in the tank during maneuvers. A secondary function is to strengthen the tank by increasing the rigidity of the relatively thin metal.

There is an honest difference of opinion as to whether baffles are needed in a homemade metal tank. I believe a large metal tank should have baffles. . . but what makes a big tank? How about 18 gallons? Certainly the design of a tank can be a factor. Tanks with large flat areas are less prone to “oiling” when reinforced by the presence of baffles. But also note that the baffle plates and the rivets that fasten them can also be put under considerable strain by the sloshing fuel. There is a possibility that the soft rivets used will fall off and the detached baffle will then become a burden. The rivet spacing used to attach the baffles should probably be no more than two inches apart.

flanges and seams

To facilitate the assembly of your tank, you will need to mold flanges into one or more of the tank shells (Figure 1). These flanges only need to be about 1/8″ wide to weld. However, a 1/8″ flange is difficult to clamp, so make yours about 1/4″ to 3/8″. About 1/18 inch of this is melted away during welding. These flanges can be used in different ways as shown in figure 2.

If you don’t like the outer lip welded flange, you can make the flush type. However, this type of flange poses an assembly problem. While the protruding flanges can be easily clamped with Cleco side clamps, small C-clamps, or even large paperclips, the flush flange must be clamped in a different way. One possibility could be pop rivets, but they are difficult to weld. It could also mean a harder job for the welder as he would have to weld around each of these assembly rivets. For this reason, the use of blind rivets as an assembly aid is not recommended. Nor the use of self-tapping screws. Clecos are better at this, and the small holes drilled for temporary insertion are easy to weld over.

A note of caution

This is not empty gossip. Many builders have experienced the trauma of torn seams in welded aluminum tanks. Some of these were spotted early on, others only when the builder spilled fuel on his leg or smelled the cockpit and suddenly realized with a panic that there were hot, throbbing exhaust systems underneath. Terror? You bet!

Every instance of a cracked fuel tank seam (out of the ones I’ve seen) happened because the seams were improperly welded. The welder in most cases had merely melted and fused the flange edges with little or no addition of filler rod. The welds in general looked nice with their small even beads. But if you have a tank that looks like this, you better inspect it before every flight or take it to the weld shop and have the welds topped up with some more filler wire.

Whoever is welding your tank should be aware that it is not an ordinary container. By that I mean that he should know that this is a fuel tank and will be subject to vibration and internal stress from bubbling fuel.

Tell your welder that merely fusing the edges is not acceptable and that beauty is not your primary concern. You want an extra heavy bead on all your seams. It doesn’t matter whether the heavy caterpillar occurs in the first pass or in the second. It is important that plenty of filler wire is added to the seams.

Standard AN aluminum fittings can be welded into the tank to connect your tank vent (Figure 3) and/or tie tanks. File or grind down the anodized layer before welding.

To my knowledge, I don’t know of a single tank welding job that has been completed without at least a few small holes leaking. So don’t blame your welder if your tank has a few too. The problem seems to stem from the need to staple the tank metal about every two inches first to keep it from warping out of alignment. Later, when the welder comes to the tack weld, there is a lot of localized metal that disrupts the weld rhythm, and the pinholes mentioned above creep past the welder.

Sealing of riveted tanks and integral tanks

Riveted tanks should be assembled by coating each rib, bulkhead, joint and surface with a thin coat of a suitable fuel resistant sealant. These sealants are not generally available and must be specially ordered. A few are listed below.

Products Research and Chemical Corporation (PRC is a registered trademark of Monsanto Company) has a product that has long been used by at least one of the major military aircraft manufacturers and a large number of BD-4 manufacturers. It is PR-1422 Class B, a filler specifically designed for sealing integral fuel tanks. A related product, PRC 1005-L, is applied as a protective coating over synthetic rubber sealants such as PR-1422. It’s a thin substance and appears to be used in a way not unlike other sloshing compounds.

The shelf life of most fuel tank sealants is fairly short – around six months at room temperature. This means you should not order the sealant unless you can use it within that time frame.

It is important that the metal tank surfaces to be coated with the sealant are sparkling clean. Clean surfaces with methyl ethyl ketone (MEK) or naphtha or other cleaner specified in the instructions. Be careful not to touch the cleaned surfaces with bare hands as the body oils will ruin your seal at every point of contact.

Applying the sealant is a very messy process, but a critical process that has no shortcuts. After the rivets are upset, run a 1/8 inch bead or bead of sealant along each rib, seam, corner, joint and rivet. Do these thoroughly and you won’t be bothered by spilled fuel or leaks. Sealant is most effectively applied to the pressure side of the tank surfaces; H. on the inside of the tank and not on the outside.

What about a sloshing connection? Some say use it, and others are a little wary of using it given the additives oil companies put in autogas. If you intend to use LPG it is advisable not to slosh your tank. The presence of methanol (alcohol) can soften and loosen the sloshing compound to the point where it could deteriorate to the point of clogging your fuel system. The ultimate consequence? Engine damage due to lack of fuel. If your tank is spilled, you should avoid using fuel with additives unless you know the additives do not contain methanol or a similarly incompatible substance. Check the inside of your tank(s) regularly if they have spilled.

Checking the tank for leaks

There is an easy way to do this. Plug all tank openings and attach a low pressure gauge to the tank sump. Add about 2 or 2 1/2 psi of air pressure. . . never more than 3psi. Coat the exterior of the tank with soapy water and brush all seams with the soapy water. Inspect every square inch carefully, looking for air bubbles that indicate a pinhole leak. Repeat the process a few times until you are satisfied that you have found all leak sources or none.

If your welded tank has a pinhole leak, mark the area with a black marker and take your tank back to the welder for correction.

When you get the tank back, check it again for leaks. Don’t assume it will be okay just because you expect it. Make absolutely sure that the tank does not leak!

It takes a tremendous amount of effort to remove and reinstall a fuel tank after you’ve got the plane flying. In some cases, you may have to remove the entire instrument panel and most of the electrical wiring to get it out.

Building a metal tank is a satisfying experience for anyone, but even more so for the builder who believes their aluminum tank will relieve them of the nagging worry that one day they will have to use fuel that could adversely affect a fiberglass tank.

“The Fuel Management Problem”, Oct. 1979

“Fuel Tanks”, Aug, Sept, Oct, Nov, Dec 1982

One of the things we take for granted about our cars is that our engine runs without a hitch. Despite being a complex machine with multiple moving parts, we expect it to simply function.

Whether you’re driving to work, to the grocery store, or to the gas station, a lot of things happen behind the scenes.

One of the most basic is the fuel, which flows from the fuel tank, through the fuel lines, and into the engine, where it is burned to propel your car forward.

To do this, however, you need a working fuel pump.

The often forgotten fuel pump is a mainstay on almost all internal combustion engines save for a few older engines commonly found on motorcycles.

Sitting either directly inside your fuel tank or just outside the tank, your fuel pump is responsible for sucking the fuel out of your tank and then feeding it into the fuel line, which itself carries the fuel to the engine.

Your fuel pump also filters out nasty contaminants in your gas tank before pumping the fuel to the engine itself. There’s also a fuel gauge attached to the fuel pump, which is literally afloat. By floating around in your gas tank, it will show you the fuel level on your dashboard.

There are two types of fuel pumps, the electronic fuel pumps found on newer vehicles and the mechanical fuel pumps found on older models.

The first electronic fuel pumps were developed in the late 1920s and incorporated into US vehicles in the 1950s, becoming commonplace in the late 1980s through the 1990s.

The electronic fuel pump uses an electromagnetic switch in conjunction with a diaphragm to provide suction to draw fuel into the chamber.

A mechanical fuel pump uses a similar diaphragm and valve as the electric fuel pump, but is driven by either the camshaft or a special shaft that runs off the crankshaft.

The good news is that both types of fuel pumps are fairly reliable, often lasting in excess of 100,000 miles.

The bad news is that they run out, and when they do your car isn’t going anywhere fast.

To be honest, it’s not going anywhere at all!

How long does a fuel pump last?

The average fuel pump lasts about 100,000 miles, although I’ve seen a fair share of cars with the original fuel pump still working properly after 200,000 miles. Why do some fuel pumps last longer than others?

There are a couple of reasons. In general, you can expect your fuel pump to last longer under all circumstances if you use higher quality gasoline and keep the tank at least a quarter full.

Here are my recommendations for keeping your fuel pump running for as long as possible:

Always keep your fuel tank at least a quarter full. Your fuel pump can overheat or dry out and crack if there isn’t enough gasoline on a consistent basis.

Gas acts as a coolant for the fuel pump and when the tank runs empty there is no liquid to cool the pump. Overheating shortens fuel pump life.

The more gasoline you have in the tank, the easier it is for the fuel pump to work because the increased weight puts pressure on the fuel pump. Without this pressure, the fuel pump has to work harder, which can lead to faster wear.

Replace your fuel filter frequently. Impurities and any residues of petrol or dust and dirt that got into the tank will sink to the bottom. If the fuel at the bottom of the tank is sucked into the fuel pump, the deposits can cause damage. The fuel filter can protect the injectors and engine from dirt, but the pump will be affected by the dirt.

Make sure you have a good seal with the gas cap. When the gas cap is open, air and debris can enter your fuel tank, which can damage your fuel pump.

Avoid petrol pumps and service stations that appear to be poorly maintained or are otherwise rusty/dirty. Water in the gas or corrosion on the nozzles can damage the fuel system and shorten the life of the fuel pump. Cheap gas is fine, as fuel quality is well regulated in the US, but the occasional ramshackle gas pump remains. As recently as 2012, there was an issue at BP gas stations in Indiana, Illinois and Wisconsin, BP that contaminated over 8 million gallons of gas.

Signs your fuel pump is on its way out

Rust, dirt or deposits in the gas tank can destroy a fuel pump very quickly. Older steel tanks will rust, while plastic tanks will start to deteriorate after 8-10 years.

Diagnosing a dead fuel pump is usually fairly easy, saving you on testing and diagnostic costs. What usually happens is the car has trouble starting and frequently dies. Finally, the car refuses to start itself, even though the engine cranks itself and gets plenty of juice.

A good way to check if your fuel pump is bad is to check your fuse box. Check to see if any of the fuses have blown. If the metal in each fuse is good, proceed to the fuel pressure test port. You can get a pressure gauge for about $20 to $30 online.

Locate your car’s fuel pressure test port and start the engine. If it doesn’t get any pressure, congratulations, you have a bad fuel pump.

Don’t you feel well now?

Well, there are other signs to look out for before the car dies, which may indicate you have a bad fuel pump. If you notice any of these but your car is still running, we recommend taking your car to a mechanic before it decides to die from you.

1: Howling noise from the fuel tank

Your fuel pump will usually hum quietly when you drive in normal conditions. However, an aging fuel pump can make noise. Of course, this can also be caused by fuel conditions such as: B. low fuel or bad fuel, but in most cases this is one of the first signs that your fuel pump is on its way out.

This can be caused by dirt in the fuel pump. Unfortunately, the fuel filter doesn’t filter microscopic particles (especially dirt and metal) that can damage your fuel pump.

The only protection comes from the intake screen. The inlet strainer only blocks large particles and cannot block the microscopic particles that wear down a pump over time. As a pump wears out, it can become noisier and spin at lower speeds, causing starting, drivability, and performance issues. The first sign of this is a “confused” noise that you can hear when you turn the car on.

2: Problems starting

An aging fuel pump may struggle to generate the pressure needed to start your car. It can still pump fuel, but it may require multiple cranking of the engine or multiple turns of the key. This symptom is far from definitive as it could be a leaking fuel line or a bad starter. One way to determine this is the pressure test described above.

3: sputtering engine

A stalling engine can be caused by an improper mixture of fuel and air if your engine is likely to be running lean or rich. If you notice your engine stuttering at high RPM before returning to normal operation, your fuel pump may be to blame. Without the right pressure, your engine may not be getting the fuel it needs. This is a sure sign that your fuel pump needs to be replaced.

4: Trouble climbing hills

When your engine is forced to work harder, it uses more fuel. A prime example of this is climbing a steep hill. If you have a bad fuel pump, your car can feel like it’s severely underpowered when going uphill, even when you’re pressing the gas pedal. A weak fuel pump is unable to regulate and accurately deliver the right amount of fuel to the engine to produce the right power.

5: Random surges

An aging fuel pump can still work intermittently, sending a burst of fuel into the engine that can feel like you’re pressing the gas pedal even though you’re driving at a steady speed. If the fuel pump is working properly, it should be delivering fuel evenly to your engine.

6: Poor gas mileage

A bad fuel pump can leave your engine running on a rich fuel mixture, which can burn extra fuel. This is far from definitive, however, as this issue can be related to a number of things, including a bad O2 sensor, a cracked fuel line, or problems in the engine itself.

When Should You Replace Your Fuel Pump?

It is usually unnecessary to replace the fuel pump as a precautionary measure, but if the vehicle has another service that involves removing the gas tank and the current fuel pump has run over 100,000 miles, replacing it can save money and time in the long run.

The biggest expense (we’ll talk about that later) in fuel pump repair is the labor. If the tank is already out, you can save several hundred dollars by replacing it at the same time, since assembly typically costs less than $150, while the entire job can cost up to $600 if labor is included.

If the fuel pump seems to be surging and then not delivering enough fuel, have it checked by a qualified mechanic immediately. The fuel system is necessary to keep the car running and a poorly maintained fuel system is downright dangerous.

So is it difficult to replace a fuel pump?

Whenever I am asked this question, the answer is always “maybe”. Replacing the fuel pump is not difficult, shall we say. If you follow the right guide or get the user manual and follow step by step, you can do the repair.

It is quite possible to work with hand tools. If you are able to read these words and understand what I am saying, even if you have never worked on your own car, you will be able to replace your fuel pump yourself.

That being said, while not difficult, it is certainly time consuming, especially if you have never worked on your car before.

In my early 20’s before becoming a mechanic it took me about 6 hours of work to fix an external fuel pump on my minivan. The same work now takes about 30-45 minutes at most.

But don’t be discouraged – you can certainly do it if you have some free time and some small hand tools that you can get on Amazon or eBay.

How much does a new fuel pump cost?

Unfortunately, there is no universal answer to this question. Replacement pumps vary by make, model, year, and sometimes engine size. Replacement pumps may appear different as manufacturers occasionally update designs.

There is also the problem of replacing only the fuel pump itself, as opposed to the entire assembly itself, which consists of the fuel pump, fuel sender unit and some peripheral systems. On some newer model cars, the fuel pump cannot be replaced separately and the entire unit needs to be replaced, while in-tank electric pumps can be replaced separately.

To make this easier, I’ll give you a price range for both.

What is the cost of repairing your fuel pump if you do it yourself?

Doing the repair yourself is an excellent choice. Replacing your fuel pump is not as difficult as you might imagine. As usual, I have to give a special mention to YouTuber ChrisFix, whose excellent video I’ve attached to show you how easy it is to fix your fuel pump yourself.

I highly recommend watching this video if you decide to do it yourself. Depending on the make and model, this can be easy or time consuming. On a Camero, for example, fixing the fuel pump involves removing the exhaust, driveshaft and lower subframe only to drop the gas tank.

Most petrol powered passenger cars since 1996 have the fuel pump in the fuel tank. As a rule, the entire module is replaced – fuel pump, pressure regulator, level sensor, since the parts do not cost much more and the plastic becomes brittle over time.

Also change the fuel filter and its hoses, which are usually located above or next to the fuel tank. For a regular vehicle, the parts cost around $100. In most cases you will have to drop the fuel tank and if necessary drain most of the gas first. Some vehicles have an access panel in the body to access the top of the tank to remove the assembly without dropping the tank. Many have the assembly secured with a large steel collar, and that may require a special tool to unscrew. If you use a hammer and chisel to turn it, don’t make a spark.

Make sure you don’t use power tools because the last thing you want is a spark. That’s not what you want.

The total cost to replace your fuel pump yourself is anywhere from $20-$150 (for the part/assembly) and at least a couple of hours of your time (minimum). Depending on how long it takes for your make and model, it may be worth taking it to the mechanic.

How much does it cost to fix your fuel pump if you take it to the mechanic?

The cost of having our fuel pump repaired at the mechanic really depends on the number of labor hours it takes to replace the part.

The fuel pump itself often costs no more than $150, even for the most expensive assemblies. However, wage rates vary across the country. I checked our labor cost database again and calculated the national average labor cost.

And guess what? It costs around $90 an hour, although this can vary from $60 to $140 depending on which state you are in.

So now we just need to know the total hours worked. As a mechanic for over 20 years I can tell you this will vary greatly. Any car with an external fuel pump will be easier and sometimes take less than an hour.

However, if you need to replace the entire fuel assembly and drop the fuel tank, things can get more complicated. On average this takes between 2-3 hours.

We estimate the workload at 2 hours – even if that can sometimes be much more.

On average, you should expect to pay between $400 and $600 to have your fuel pump repaired by a mechanic. Although this can go as high as $1,000 or as low as $200. It really depends on your car.

So what do you do after replacing your fuel pump?

In my opinion, the most important thing you can do when replacing your fuel pump is to either replace your fuel tank if it’s in bad shape, or otherwise clean it. As I mentioned earlier, a dirty or damaged fuel tank can damage your fuel pump.

If you end up replacing your fuel pump but not cleaning your fuel tank, the same problem can repeat itself if the fuel pump was damaged by a dirty tank.

Whether you take your car to a technician or do it yourself, I highly recommend you follow this 10-step process to properly clean your gas tank to avoid damaging your fuel pump and doing this process have to go through again.

The 10 step process:

Empty the fuel tank into a container that can hold fuel. It may help to use a mechanical fuel siphon for this. Remove rust and dirt from the fuel tank. You can use an abrasive, something chemical, or something else. Remove the fuel pump. Swirl the petrol tank and remove all traces of petrol. Pour the remaining gas and dirt into an approved container and dispose of properly. Make sure the tank is in good condition. Look for leaks, holes, or anything else. If the tank is damaged, replace it. Clean the inside of the tank with a low-foaming water-soap mixture. Swirl the cleaning solution into the tank. Empty the container and dry with compressed air. Wipe the tank with a lint-free cloth. Make sure the tank is completely dry. You should let it dry in a shady place for a few hours.

The gas tank is one of the most important components of your car and also one of the most dangerous. A ruptured fuel tank can create a fire hazard, which in the worst case scenario can cause your car to explode. So if you have a broken or leaking fuel tank, you should have it repaired as soon as possible.

Overall, you should expect to pay an average of $1,200 to replace a standard polypropylene fuel tank. The typical price range is from $900 on the low end to $2,100 on the high end.

Materials like high-density polyethylene cost more, and you’ll have to pay more the larger your gas tank is. These prices are average prices and may vary depending on the model and age of your car and the location of your mechanic.

There are several factors that go into the cost of a fuel tank replacement. That’s why we’ve put together this comprehensive guide to the cost of replacing a fuel tank. We will cover major replacement costs as well as costs for various related repairs.

How much does it cost to replace a fuel tank?

Overall, replacing a fuel tank should cost about $1,500 on average. The typical price range is from $900 on the low end to $2,100 on the high end.

A fuel tank for an economy brand car usually costs less than one for a luxury brand.

Below is a table of the average fuel tank replacement cost for various popular cars. These costs are averages and may vary depending on the age of your car and the location of your mechanic.

Make/Model Price Honda Civic $1,500 Honda CRV $1,600 Toyota Camry $1,100 Toyota Corolla $950 Chevy Silverado $1,200 Ford F-150 $1,700 Ford Fusion $1,600 Ford Mustang $600 Nissan Altima $1,200 , BMW 3 Series $1,900, Audi A4 $2,700

As you can see, cars and trucks with larger tanks tend to be more expensive to repair. Similarly, luxury brand cars have higher fuel tank replacement costs than economy brand cars.

Associated Replacement Costs

Most of the time, fuel tank problems don’t manifest themselves alone, especially if your car is on the older side of things.

fuel lines

Fuel lines are another core component of your fuel system, carrying gasoline from the tank to the pump and engine. Most fuel lines are made of high density reinforced nitrile rubber with coatings to prevent fuel degradation.

It costs an average of about $1,000 to completely replace your car’s fuel lines. Below is a table showing the average cost of replacing fuel lines for different car models.

Make/Model Price Honda Civic $700 Honda CRV $600 Toyota Camry $690 Toyota Corolla $950 Chevy Silverado $1,400 Ford F-150 $950 Ford Fusion $1,000 Ford Mustang $820 Nissan Altima $1,200

fuel pump

The fuel pump is another important component of your fuel system, drawing fuel from the tank and pumping it through the fuel line to your engine.

Fuel pumps are designed to deliver just the right amount of fuel to achieve the optimal air/fuel ratio for a combustion reaction.

Therefore, one of the most common signs of a faulty fuel pump is engine stuttering and stalling. The average cost of replacing a fuel pump averages about $800.

fuel tank parts

Instead of hiring a mechanic, it is possible to buy the fuel tank parts online and do the replacement yourself. You can often find a compatible fuel tank for your car for up to 70% cheaper than going to a mechanic.

The main disadvantage of this approach is that you have to replace the tank yourself, which may require special tools.

Below is a table showing the cost of replacing different fuel tanks.

Product Price AM Honda Accord Fuel Tank $180 Dorman 576-605 Fuel Tank $120 Spectra Premium HO17A Fuel Tank for Acura $250 AM Honda CRV Fuel Tank $170 Garage-Pro Toyota Corolla Fuel Tank $150 Chevy GMC Fuel Tank $105 Dorman 5760814 Fuel Tank for Nissan $150 Dorman 576 -550 fuel tank for BMW $200

Factors affecting fuel tank replacement cost

tank materials

Most modern gas tanks are made of propylene, polyethylene or ethanol. Some older cars still use steel, iron or aluminum tanks. The most common material is propylene, which is also the cheapest material.

Steel and other metal tanks are mostly used on older cars. We recommend replacing your tank with the material from which the original tank was made.

age of the car

The age of the car also affects the cost of repairs. The older your car, the more likely it is that you will need a different type of repair. Common parts associated with the fuel tank include the fuel pump and fuel relay lines.

As your car ages, your mechanic may recommend replacing several core components of your fuel system.

Car make/model

As always, the make and model of your car also affects the cost. Repairing an economy brand vehicle like Toyota costs significantly less than repairing a luxury brand like BMW or Audi.

Certain car models can also have unique designs that require special tools or expertise to be properly maintained. For example, foreign-brand cars usually require a specialized mechanic and tools for maintenance.

tank size

Most important is the tank size. The larger the tank, the more the replacement usually costs. For example, repairing a 13 gallon Toyota Corolla tank will most likely cost less than repairing a 24 gallon Chevy Silverado tank.

Signs of a bad fuel tank

Here are some of the most common symptoms of a failed fuel tank.

Visible dent/cracks

The most obvious sign of a failed fuel tank is visible cracks or dents in the casing. If you can’t see cracks, you can often feel them by running your fingers over the plastic surface. Small dents may not need repairing, but you should bring your car in if you find any tears in the vinyl.

leaking gas

If you find gasoline leaking from under your car, the most likely places it is coming from are the fuel line or the gas tank. If the gas leak is near your rear axle and wheels, the fuel tank is probably the culprit.

Sometimes fuel leaks out and evaporates without leaving a visible stain. One way to determine leaking gas is if your car is leaking gas while it’s not on.

rust in the filter

Metal tanks can develop moisture inside the reservoir if water becomes trapped inside. One way to tell if the inside of your tank is there is to check the fuel filter. Rust in the fuel clogs the filter, as do other contaminants.

smell of gas

If you notice a strong smell of gas next to your car, a leaking gas tank could be the cause. Cracks in the top half of the tank can allow the gas to escape as vapor and create a pungent odor near the rear of your car.

If you smell gas in the air, call a mechanic immediately as gas fumes can pose a health and safety hazard.

frequently asked Questions

How much does it cost to replace a fuel tank?

On average, it should cost around $1,500 to replace a fuel tank. The typical price range is from $900 on the low end to $1,500 on the high end. Propylene tanks tend to be the cheapest and most commonly used.

How often do I need to replace a fuel tank?

In general, if your fuel tank is made of plastic or any other synthetic material, it should show signs of aging after about ten years.

Metal tanks can also last around ten years as long as they are kept free from moisture and rust. In the best case, a fuel tank lasts up to 20 years.

What is the best material for a fuel tank?

For modern tanks, the best material is high-density polyethylene. Polyethylene is durable, heat resistant and non-reactive so it will not rust or corrode.

Polyethylene is also very light and relatively cheap to manufacture and install. Finally, polyethylene is resistant to cracks and breakage due to temperature changes in winter.

Can I drive with a bad fuel tank?

Your car will still start if you have a cracked or leaking fuel tank, but driving with spilled gas is very dangerous. The gas can ignite and cause a fire in the tank or in the car.

If you notice your tank is losing gas, you should try draining the tank and call a mechanic.

Where is the fuel tank?

On most modern sedans and SUVs, the fuel tank is located just above and in front of the rear axle. The fuel tank is usually located outside of your car’s crumple zone to prevent it from being crushed and leaking in a crash.

last words

Fuel tanks are an important and often forgotten part of your car. A failed fuel tank can not only affect vehicle performance, but also pose a huge safety and health hazard.

Replacing your gas tank can also increase the life of your car in general. As always, get quotes from multiple mechanics to get the best price possible.

Fuel tanks, also known as heating oil tanks or heating oil tanks, typically last around 15 to 30 years. While installing fuel tanks isn’t the cheapest project, the cost of a leaking tank that causes environmental damage can be far greater. Therefore, if your fuel tank is at least 15 years old and an inspection reveals a problem, you should replace it. This buying guide examines how much this could cost you, in addition to basic information about fuel storage tanks.

What you should know about fuel tanks #

Below is some information on heating fuel tanks that potential buyers should find helpful:

Above Ground vs. Below Ground: The two basic types of heating oil tanks are above ground and below ground. Above ground fuel tanks typically hold 275 or 330 gallons. While they take up space in your home, they are easier to install, repair and remove. Underground fuel tanks are larger, holding about 500 to 1,000 gallons, but are more expensive to remove, install, and inspect.

The Cost of an Oil Leak: While heating oil poses no significant risk of explosion, the consequences of a leak, particularly in the case of an underground tank, can be very damaging to your wallet (not to mention the environment). Repairing leaks in underground fuel tanks can easily cost $5,000 to $10,000, and expenses of $20,000 to $100,000 or more are not uncommon.

Prevent Leaks: The most common cause of leaking fuel tanks is corrosion caused by water. If you have an outdoor tank, it’s a good idea to protect it from the elements by building an “oil shed” or similar enclosure. And especially if your tank is 10-15 years old, you should look out for signs of leaks, such as:

Oil leaks faster than normal

Oven/water heater not working properly

oil stains (above ground)

Dead vegetation (underground)

Tank fittings and lines not clean and tight

If any of these telltale signs of a fuel leak are present, it might well be time to put in a new fuel tank.

Fuel tank cost Installation cost #

The actual cost of installing the fuel tank may vary based on location, location of the tank, contractor, and other factors. The following prices should only serve as a rough overview.

An important consideration in fuel tank installation pricing is whether the tank is above ground or below ground.

To remove and replace an above-ground tank should set you back around $1,500 to $2,500. For an underground tank, the total cost could be double that, or $3,000 to $5,000 and up.

With an underground tank, the total cost can be double or more. Soil testing for contamination will set you back an additional $300 to $600. If contamination is detected, expect your costs to skyrocket relative to the cost of cleaning.

Everyone is dependent on their car for many things. For many people, their car or truck is their means of getting to work or even transporting their family. Can you imagine the problems it would cause if your car stopped running in the morning?

A gas leak in your car could actually cause this problem when you least expect it. Today we’re going to discuss how to tell when you have a fuel leak, what to do about it, and how much it will cost to fix a gas leak in a car.

The average cost of repairing gas lines in cars is $90. The cheapest repair would cost $60 for a simple gas line repair. The most expensive would cost $120 for a gas line replacement.

Of course, a whole fuel system with many different and complicated parts has to be considered. You also need to consider a problem in the gas tank or fuel injection system, and there are other reasons for gas leaks in a car.

How do I know if my car is losing gas?

Sometimes it’s easy to spot when you have a fuel leak in your car, sometimes it might not be so obvious. So you can be sure whether your car has a gas leak or not.

Color: Gas leaks are usually clear, however some gas additives can cause the gas to be dark in color or even black in appearance.

Smell: We all know the smell of gas. In fact, you may be able to tell you have a fuel leak by the smell of gas before you actually see it. You should not smell any gas while driving, if you do this indicates that you probably have a leak in the fuel line.

Disappearing Gas: If you notice that your gas is decreasing too quickly or seems to disappear overnight, this is a good indicator that you have a gas leak.

A simple way to find out if your car is actually losing gas is to place a piece of newspaper or cardboard under your car.

This is a great idea as it prevents slippery liquids from collecting on the floor and becoming a hazard and you will learn a lot more about the liquid coming out of your vehicle. You can see the color clearly and catch any smell emanating from the liquid.

Can I drive my car if it’s losing gas?

It is never safe to drive a car with a gas leak. Technically, the car will still run, but it is absolutely not safe to drive. A car with a fuel leak can pose a hazard to other drivers as fuel left on the ground is slippery and can cause accidents.

The vehicle could potentially catch fire or even explode, causing serious injury to you and others, including death. This is a risk not worth taking.

How much does it cost to fix a gas leak in my car?

There are many things that can cause a gas leak, and gas can leak from many places in a car. Each of these things comes at a different price and of course the make and model of your car as well as the mechanic you choose play a big part in determining the final price you will pay.

What Causes Gas Leaks in Cars?

Fuel Lines: The most likely reason your car is losing gas is that you have a leak in your fuel lines. They tend to crack or break with age. Basic wear and tear alone can deal this damage given enough time.

Gas Tank: Another common place where a gas leak occurs is in the gas tank. Age alone can often allow your gas tank to corrode, but collisions, potholes and even sabotage are also often the cause of damage to the gas tank.

Fuel Injection System: This is the system responsible for moving the gas and there are seals and O-rings in this system. It is not uncommon for these seals and o-rings to crack due to age.

Fuel line repair costs

A busted fuel line is the most likely reason your car is losing fuel. If that’s the case, you might get away with as little as $50-$70 to fix the line. You’ll be thinking closer to $100-$120 if you need to replace the fuel line entirely.

Gas tank replacement cost

If damage to your gas tank has caused a leak and you want to replace the gas tank, it will likely cost you between $1,300 and $1,400.

Gas tanks themselves cost around $1,000, but that depends somewhat on the make and model of your car. Mechanics average between $250 and $350 for a good job like this.

Can a leaking gas tank be repaired?

Yes, in many cases a leaking gas tank can be repaired. You must clean the tank before attempting to repair it.

Cleaning the tank is an intensive process of draining the remaining gas, removing the tank, then cleaning and then repairing it. Any mistake in this process can cause serious and expensive problems. This is best left to an experienced mechanic.

Can I use Stop Leak in my gas tank?

For hairline cracks, pinholes, and very small holes under about half an inch, a leak stop can be effective. However, it is easy to use too much Stop-Lick and this will permanently damage it

your engine. While the stop leak will stop small leaks in your gas tank, it can also clog small parts like fuel injectors.

How much does it cost to repair fuel injectors in a car?

The cost of the parts to replace fuel injectors varies greatly between car makes and models. Parts can range from $150 to $600 and even more. Work for the job is likely to be between $200 and $300 regardless of what type of car you drive.

What about bad gas?

There are many different problems that can arise with the fuel itself. This may mean that your fuel problem is not a leak but the actual gas itself. Here are some common bad gas problems.

Stale Gasoline: In old vehicles that are being rebuilt or in second (or replacement) cars, it is not uncommon for gasoline to remain in the tank for a long time. If gasoline has been in the tank for weeks or even longer, its chemical composition can change and cause the gasoline to go bad. This can often be remedied with gasoline additives that help stabilize the gas.

Gas mixed with water: If water is damaged in your gas tank, your engine will “stutter”. This can damage your engine and you will need to make an appointment with a mechanic to check the tank and water pump

Rust in Gasoline: When your fuel tank rusts, the rust particles can travel with the gasoline through the injectors and into the engine. This can lead to clogging of the injectors, the engine or the fuel filter.

Sugar in the Gas: Sabotage is more common than we would like to believe. If someone puts sugar in your gas tank, it can seriously damage your fuel pump. If you think this has happened to you, you should see an auto shop or mechanic immediately.

How much does it cost to fix bad gas in a car?

If you got bad gasoline in your vehicle (other than just old gasoline), you need to have the fuel system flushed. This is expensive work. This can be as little as $400 for some cars, but it can cost a lot more, up to $1,600 and even more for some luxury vehicles.

How do I fix a gas leak in my car?

A gas leak in a car is very dangerous, whatever the cause. Gasoline is both flammable and combustible, so you shouldn’t drive your car with a fuel leak. Don’t wait for a gas leak in your vehicle to be repaired.

Repairs to fuel lines, injectors and gas tanks are complex and varied. Your mechanic will inspect the car’s fuel system, checking for leaks, damage, and other problems. They can expertly carry out the necessary repairs and get you back on the road.

While a stop leak can be an occasional fix, the possibility of the damage it could do to your car isn’t really worth the risk. There is no quick fix when your car has a gas leak. Make an appointment to see your mechanic and get the job done right.
