Should my fuel water separator be full?
Should You Pre Fill A Boat Fuel Filter or Water Separator? Yes, pre-filling a boat’s fuel filter or water separator is a great habit. You won’t cause any harm to the engine and it will make your engines fuel lift pumps job much easier. This eliminates the introduction of a large amount of air into the fuel system.
Why is my fuel filter not filling up?
Old gas lines become perished and porous, and a fuel pump may draw in air through the porous lines, which will reduce its ability to fill the filter. Check over all your gas lines, bend them, and look for any sign of cracking. Check your line clamps too, a vacuum leak at a clamp will have the same effect.
How much fuel does a fuel water separator take?
Typically, the larger the engine, the larger your fuel water separator should be. As a general rule of thumb, the required flow rate of your fuel water separator is about 10 percent of the rating of your engine. As an example, a 200-hp engine would require a 20-gallons-per-hour (GPH) filter.
How do I know if my fuel water separator is bad?
Hesitating Engine With Heavy Load
If your fuel filter water separator isn’t working properly or is clogged, then water and other pollutants could be mixing into the fuel injector and causing damage inside your engine. You’ll also know there’s an issue if the check engine light switches on.
ATV Fuel Filter Not Filling Up (Top 8 reasons)
One of the worst things that can happen on the water is your boat’s engine stalling and leaving you stranded. It’s even worse when you’re out in open water.
Your engine can fail for a number of reasons, one of which is failure of your spin-on fuel filter.
The goal of a primary fuel filter is to keep contaminants out of your machines. In addition, a diesel fuel water separator separates water from the fuel entering your engine.
Here are nine signs you need to change your boat’s fuel filter to avoid engine failure in the future.
1. Engine starting problems
There are many reasons why your engine is having trouble starting, such as: B. an empty gas tank, damaged fuel lines or a closed gas tank vent. There can also be problems if contaminants get into your fuel system or if the fuel filter is clogged.
If your engine is having problems, you may need to check if your filter is working properly. While there is a chance your engine is already damaged, it could just be a problem with your fuel.
2. Rough idle
A rough or uneven idle can be a sign that your engine is misfiring. This is due to the air-fuel mixture being disturbed and the engine moving.
Misfires are usually difficult to isolate as they are caused by many different system faults. Changing your fuel filter should be the easiest step when taking care of the problem.
If the rough idle persists with a fresh filter, it may be best to take it to an expert.
3. Motor hesitation under heavy load
An engine that stalls or stalls under load is either not firing, isn’t getting enough fuel, or is sucking in too much air.
If your fuel filter’s water separator is not working properly or is clogged, water and other contaminants can mix into the fuel injector and cause damage to your engine. You will also know there is a problem when the check engine light comes on.
4. Starting and stopping
You also know that if your engine starts and stops randomly, your filter needs to be checked. You’ll be on the water and your engine will sputter and stop before starting again, only to stop again.
This, in turn, indicates either a problem with the engine or a fuel quality problem. Either too much contamination is getting through the filter, or not enough fuel is getting through.
5. You changed the gas
Fuel can become contaminated if left in a fuel tank for too long, which is why there is a spin-on fuel filter. But the filter can also become clogged and must be replaced.
This is especially important if the area you are fueling your boat in has recently switched to ethanol formulated gasoline. Ethanol cleans fuel systems, which means your filter will pick up the excess waste.
Luckily, changing spin-on fuel filters is easy. Maintaining proper fuel flow is key to a long-lasting boat engine.
6. You get an oil change
The oil should be changed every 50 to 100 hours of operation. Neglecting this can cause irreversible damage to your engine and leave your boat landlocked.
While you’re getting your oil changed, you might as well swap out the spin-on fuel water separator and have everything else checked and serviced. Take every opportunity you have to sail smoothly.
7. Brown fuel or filter element
If you find your fuel has turned brown or muddy and your filter element is becoming less clean, contaminants are likely getting through.
Changing your spin-on fuel filter is a good first step, but there may be secondary filters deeper inside the machine that aren’t as easy to reach. In these cases, you should arrange a visit to a marine technician to clean your fuel tank, change filters and perform other maintenance.
8. Reading the high vacuum gauge
One of the few essential fuel system troubleshooting tools is the fuel filter vacuum gauge, which tells you how much pressure is on the filter.
If the vacuum increases, the filter must be changed. However, before working with possibly contaminated fuel or a filter, the baseline must be set with clean fuel assemblies.
Another thing to note is that while the vacuum gauge will indicate a problem, most likely in your fuel filter, it could also show signs of a clog elsewhere in the fuel pickup or rail.
A good vacuum gauge will tell you when to change your filter when absolutely necessary, which can save you time and money.

9. It’s been more than six months
Finally, one of the most important signs that you need to change your spin-on fuel filter is when it has been at least six months since it was last changed.
This is important, especially if you don’t take your boat out often, as the fuel in your tank can settle and cause a number of problems when injected into the engine. This doesn’t have to be exactly six months, but the best way to make it a routine is to actively use it.
And make sure you follow your boat’s manual when replacing or installing a filter unit.
Bonus tip: plan ahead and check out this spin-on fuel filter

WHY IS THE FUEL FILTER SO IMPORTANT?
The fuel filter filters dirt and prevents it from entering the fuel system.
HOW DO YOU KNOW IF YOU ARE DRIVING WITH A CLOGGED FUEL FILTER?
Here are five of the symptoms of a bad fuel filter to look out for:
You have trouble starting the car. If the problem is the fuel filter and it is not changed soon, you may find that your vehicle will not start at all. Misfire or rough idle. A dirty fuel filter can prevent the engine from getting enough fuel. vehicle standstill. Nobody wants to suddenly stop in traffic! But that could happen if you ride with a filter that’s past its prime. Failure of a fuel system component. Electric fuel pumps can fail prematurely when trying to force fuel through a dirty fuel filter. Loud noise from the fuel pump. Sudden, unusual noises could alert your vehicle that something is wrong.
DRIVE TOO LONG WITH A CLOGGED FUEL FILTER AND THE CHECK ENGINE LIGHT COULD ILLUMINATE
Many vehicles have sensors that monitor the fuel system. If the Malfunction Indicator Lamp (MIL) or Check Engine Light comes on, it means the sensors have detected a problem.
There may be a simple, affordable solution to these serious problems: change the filter. Consistent, timely maintenance of the fuel filter is important for reliable driving behavior. A fresh filter reduces contamination and helps prevent damage to your engine and fuel system.
HOW OFTEN SHOULD THE FUEL FILTER BE CHANGED?
It’s often recommended to change the filter every 2 years or every 30,000 miles (whichever comes first), but that’s a general suggestion. If you drive a lot on unpaved roads or through highway construction sites that can kick up a lot of dust and debris, you may want to change your fuel filter more frequently. Refer to your vehicle’s owner’s manual for the recommended interval for your specific vehicle.
Don’t skip a scheduled maintenance check, but don’t hesitate to have your vehicle professionally inspected between appointments if you notice any of the five listed symptoms of a bad fuel filter. Visit any of the 2,000 Jiffy Lube locations across North America and a trained Jiffy Lube technician will:
Ask about your driving style to determine how it can affect your vehicle’s fuel system
Describe the symptoms of a bad fuel filter and ask which ones you may have
Remove the used fuel filter
Replace the used fuel filter with a new filter that meets or exceeds the manufacturer’s recommendations
DO NOT FORGET YOUR VEHICLE’S OTHER FILTERS
The fuel filter isn’t the only filter that works hard to ensure peak vehicle performance. When you visit Jiffy Lube, the technician will also visually inspect the following:
engine air filter. Just as the fuel filter helps capture debris in the fuel, the engine air filter protects the engine from airborne contaminants.
transmission filter. Your automatic transmission relies on the filter to prevent dirt and debris from entering the hydraulic system.
cabin air filter. The cabin is where you and your passengers sit, and the cabin air filter helps remove dust, pollen, and mold so you can all breathe easier.
The Jiffy Lube engineer will let you know if a replacement is recommended, but will not perform any work without your consent.
YOU CAN DEPEND ON JIFFY LUBE
Regular, professional preventative maintenance will help keep your vehicle performing the way it was designed. Jiffy Lube technicians are rigorously trained and use quality products. That’s good for you, because your car, truck, minivan, or SUV is more likely to be up and running when you need it most. It’s also good for your budget because if caught early, small repairs — like changing your fuel filter — won’t turn into expensive repairs.

Do you have to prime fuel filter?
Additionally, you need to prime the fuel filter to ensure fuel is circulating in your fuel system once again. Individuals often make the mistake of cranking the engine in an attempt to prime the pump, which can wear down your battery and, in some cases, fail to recirculate your fuel.
ATV Fuel Filter Not Filling Up (Top 8 reasons)
Manual priming of the fuel filter
When replacing a fuel filter, it is necessary to remove any air bubbles that have been introduced into your fuel system. You will also need to prime the fuel filter to ensure fuel is circulating back into your fuel system. Individuals often make the mistake of starting the engine to prime the pump, which can wear out your battery and in some cases not return your fuel. Most diesel engines these days have a manual primer pump, as well as a bleed screw that allows you to bleed the air and prime the pump. To operate these manual functions, pump the primer handle (this may take up to 50-500 pumps) while turning this screw until the hissing sound of escaping air dissipates. Once this occurs you can tighten the screw and try to crank the motor.
Prepare with ignition
On some diesel engines, priming the fuel pump can be as simple as turning the ignition key to “run” for a few seconds, turning it off, and then repeating it up to four times. This restart procedure is most likely recommended by your manufacturer and will allow you to restart the engine after a few minutes. Continue into the fourth or fifth turn and crank the engine, which should start. Make sure you run the engine for 30 seconds before stopping the engine and inspecting the fuel filter for leaks yourself.

If you are aspirating a diesel engine, make sure your engine starts because the fuel filter has diesel available and that all air is removed from the fuel system. This may be necessary when changing the fuel filter or when your diesel engine has run out of fuel. If your engine still won’t start, it could be a sign of a more serious problem that you should have a certified diesel mechanic examine.

How does a fuel water separator work?
The principle behind this filtration system is surprisingly simple; the top of the filter consists of a paper element and the bottom of the filter is a holding tank or bowl. Since water is heavier than petrol, water sinks to the bottom of the filter where it stays until it is emptied.
ATV Fuel Filter Not Filling Up (Top 8 reasons)
Author: Stuart Buckingham Date of publication: November 21, 2018
Bad fuel can quickly cause problems for outboard motors by clogging fuel injectors, sticking carburetor jets or all kinds of operational problems that can lead to shortened outboard motor life and high repair costs.
Water and contaminants can get into a boat’s fuel tank in a number of ways, such as: e.g.:
– improperly positioned fuel tank vents and fuel filler necks,
– Condensation in the fuel tank or
– by buying contaminated fuel at a gas station.
Breathers and filler necks can easily be replaced or relocated, but there is little you can do about condensation forming in your fuel tank or about contaminated third-party fuel. However, the solution to avoiding this is to install a water separating fuel filter assembly and here is why.
A water separating fuel filter is designed to catch contaminants or water before they reach your engine. The principle behind this filter system is surprisingly simple; The top of the filter consists of a paper element and the bottom of the filter is a collection container or bowl. Since water is heavier than gasoline, water will sink to the bottom of the filter where it will remain until drained. In my opinion, the best version of water separators is the clear bowl type. They allow you to see if water is collecting at the bottom of the system and then drain it using the integrated tap.
For routine maintenance, the filter cartridge should be replaced and the existing bowl reinstalled. Installing a water separating fuel system is easy and you don’t need much mechanical knowledge to fit it. It really should take between 15 and 30 minutes, but can take longer if the area you’re attaching it to is difficult to access or needs to be modified, and will cost you around $50 to $85 depending on the brand and the setup you need.
It’s good to know that you’re protecting your outboard if water or other contaminants get into your fuel. Installing one is one of the wisest decisions you will make when caring for your outboard.

Re: I can’t get fuel through my fuel/water separator!!! Of course it does, but you’re not doing this to replace the check valve, you’re doing this to speed up the priming process, if you’re not passing gas through the much smaller orifices in the fitting, which takes longer. After doing this many times with long fuel lines, removing the restrictive engine fitting from the line and you can’t just pull it off or it’s tight halves the prime time. As for filling a racor in 6 pumps, that’s a terrible liberality Guestimate, but we’re not talking about a primed system, we’re talking about an air-filled system, you can’t compare the two. and last time I checked 6 pumps you may have gotten 1 cup of gas not a full liter of gas, it takes an average of 2-3 pumps on a primed system just to fill the 5/16″ fuel line from bulb to Engine to harden the bulb to start the engine
Why You Should Pre Fill A Fuel Filter or Water Separator!
You could spend hours reading forums or watching YouTube videos of people discussing whether or not you should prime fuel filters and oil filters.
It seems to me that the oil filter debate is usually between diesel guys. I’m not going to discuss that here, so if you’re here for diesel oil filters, that won’t help you. It’s about:
Should you prime a boat fuel filter or water separator? Yes, it is a good habit to prime a boat’s fuel filter or water separator. You will not harm the engine and the work of your engine fuel feed pumps will be much easier. This eliminates the introduction of a large amount of air into the fuel system.
Here is a list of the most common pros and cons of this debate. Along with the greatest reasoning behind both sides of the story.
How the fuel system works
Knowing just a little bit about the fuel system can help you decide whether priming the fuel filters is a good or bad thing.
By no means will this be a massive comprehensive or exhaustive description.
This only helps in understanding what is going on.
So all engines, whether inboard or outboard, gas or diesel; Have fuel pumps that draw fuel from the fuel tank.
Each manufacturer has their own specifications for each pump’s vacuum and what they can pull.
All engine manufacturers agree on this, whether petrol or diesel; is that introducing air into the system and running dry air through an injector is very harsh on the injector and can cause major damage to the injector.
Now to the pre-fill debate. Some say you should, some say you shouldn’t.
When changing the fuel filters on your boat (including any with a fuel/water separator); When you put the dry filter on the bracket, you have just introduced a huge amount of air into the closed fuel system.
Closed means there are no leaks from the intake pipe in the fuel tank to the lift pump on the engine trying to suck the fuel out of the tank.
The distance from the tank to the pump must also be taken into account.
The amount of air that is in the fuel filter over a short distance does not put as much strain on the pump as over a longer distance. Regardless of the distance, however, the fuel pump is still working extra hard.
Why we pre-fill fuel filters
This is the main reason I pre-fill all of my fuel water separators. This eliminates the problem of the air pocket in the fuel system.
With a full water separator, the problem of having all that air in it goes away. We are now talking about having a small amount of air working its way through the system; without air blocking the fuel pumps.
Air pockets in fuel pumps can be a huge nightmare. Yes, you can damage the injectors and cause serious problems.
Remember we are talking about water separators and boat fuel filters. Not the engine fuel filters. We’ll talk about that next.
I’m sure the whole goal for most of you is to get the job done right and quickly with no damage to the engine. This is why priming fuel filters is such a good habit.
What to do if the engine does not start after changing the fuel filter?
Sometimes the engine can’t get the air out of the system and you have to fiddle with the primer ball on the engine side of the water separator.
If you change fuel filters and don’t prime them; Then the next task becomes removing the air from the fuel system.
This means you manually purge the air from the fuel system. The process for this is fairly simple but can be quite cumbersome depending on where the primers are located in the boat.
To bleed a fuel system on a boat:
Make sure the primer ball is on the engine side of the water separator bracket.
Disconnect the fuel hose that exits the primer ball and goes to the engine.
Point the arrow on the primer balloon skyward or hold the primer balloon vertically up or down. (This is extremely important, DO NOT hold the primer horizontally.)
Then, squeeze the primer ball and, before releasing, place your finger on the barb you removed the fuel hose from.
Then release the lightbulb.
After the bulb expands, remove your finger and quickly squeeze the primer bulb.
Then, with the pear squeezed, quickly place your finger back on the barb and release the pear.
Repeat this process until you have manually bled the air from the fuel system and there is fuel in the filler bulb.
Then squeeze the bulb until a small amount of fuel comes out and quickly put the fuel hose back on the bulb.
Continue pumping the primer bulb until you have filled the engine with fuel and are able to start the engine.
Don’t forget to re-tighten the hose clamp!
More information on priming a fuel system or locating an air leak. Check out an article we wrote about the steps you need to take to fix the problem!
What about engine fuel filters?
Engine fuel filters are a different story. I think we are talking about a small amount of air here.
Personally, I don’t prime the engine’s fuel filters. Unless it’s a canister or water separator type filter.
It is important to know that I mainly deal with outboard motors. So the fuel filters they have are mostly in-line fuel filters with quick disconnects.
This allows the filter to quickly snap into the fuel lines or a small fuel filter element that sits in a small cup that holds a small amount of fuel.
I’m sure you could prefill this if you’d like, but I don’t think it would do all that much for you.
Again, I personally do not pre-fill any of the engine fuel filters, with the exception of the canister or water separator style filters, and we never have any issues with air blocking the fuel system or running the fuel pumps dry.
What about engine oil filters?
The same could be said about the oil filters.
Speaking of gasoline outboard motor industry; Most oil filters are placed on the engines upside down or at an angle downwards.
Pre-filling is therefore practically impossible. Unless you like making a big oil mess.
Another thing about priming the oil filters; I don’t really understand why it’s necessary when we’re talking about gasoline outboards.
Diesel can be different. There seems to be a massive controversy among mechanics on this topic.
Having limited experience with diesel I will leave this debate alone!
But back to the outboards. Most outboard motors work in such a way that when the crankshaft rotates, it drives the oil pump.
So when the engine cranks, it forces slightly pressurized oil through all the oil passages, including the oil filter.
It’s not like it immediately blows 80 PSI of oil into the filter and shreds the filter element; which is quickly filled when the engine is started and the oil system is running properly and without damage again.
So, as far as priming the oil filter on an outboard is concerned, that’s a big no.
The advantages of pre-filling
Back to the topic of fuel water separators. Pre-filling has many advantages.
We have already addressed the largest. This eliminates the problem of filling all fuel systems with air.
Saving on fuel injection and reducing the intake load on the engine’s suction pumps.
It also saves you the time and hassle of removing the primer ball and going to town to manually purge all air from the fuel system.
So there are many reasons why we pre-fill all our fuel water separators in the field.
The disadvantages of pre-filling
As far as the cons go. I can only think of one reason. This checks for air leaks in the fuel system.
Theoretically, if the fuel lines have no leaks and you put the filters dry. The fuel pump should be able to suck fuel out of the tank and flush the air out on its own.
Again we are talking about stress and a lot of work that is put on the fuel pumps. But technically it should be able to do this without any problems whatsoever.
So this is a kind of self test for air leaks in the fuel system. What, to be honest, if there are air leaks in the fuel system; you will find out about it.
We talk about running problems, lack of fuel and WOT problems.
All sorts of intermittent problems can occur when air is introduced into the fuel system and the fuel is atomized before the engine is doing it properly with the injectors.
Tell us what you think
So what’s your opinion? In your opinion, is it better to fill in in advance or not?

ATV Fuel Filter Not Filling Up (Top 8 reasons)
Your engine feels sluggish and stalls. You check the bottle filter and see that it is only half full. What’s happening?
The top 8 reasons why an ATV fuel filter won’t fill are:
1 Low fuel level
2 Fuel tap not fully open
3 Fuel filter clogged
4 filters installed incorrectly
5 Porous gas lines
6 Gas tank clogging
7 Fuel pump error
8 Air Sealed Carburettor
In this post you will learn about the most common reasons why your gas filter is not filling and what you can do about it.
Types of fuel systems
Most ATV fuel systems are fairly basic, but other more modern bikes may use a more sophisticated computer controlled fuel injected setup. The most basic system uses a gravity-fuel mechanical slide carburetor.
With a gravity system, the gas tank must be positioned higher than the carburetor. This is an easy fix and works well until your gas tank runs low and you’re climbing steep hills.
Adding a fuel pump solves this problem, and most modern ATVs have one built in. Common types include electric, mechanical, and vacuum powered pumps. A common arrangement is a vacuum drive pump positioned upstream. It sucks the gas from the tank through the lines, filters it and pumps it into the carburetor fuel bowl.
1 Low fuel level
A low gas level can result in the filter not filling, especially when driving on uneven surfaces. Gravity feed systems suffer greatly from this condition and can cause the bike to stall or hesitate.
2 fuel cock
Your bike is equipped with a fuel cock that must be turned to the “on” position. A defective valve could prevent adequate gas flow from filling the filter. If you remove the fuel line before the petcock, you can check the flow.
3 fuel filters
A clog in the filter will obviously restrict flow and prevent the filter from filling. If your filter looks dirty or old, replace it. This is a simple fix. Your ATV may be equipped with a secondary filter. It is not uncommon to have a reusable screen filter integrated into the carburetor. Check your carburetor manufacturer and do your research. A throttling of the integrated carbohydrate filter can also cause a throttling further upstream in the second filter.
4 filter direction
Most in-line filters are directional, and if so, they have an arrow pointing to the carburetor (flow direction). Directional filters can have a simple integral one-way valve to prevent gas backflow. Incorrect installation will result in a fuel restriction.
An incorrect filter size can also lead to a half-filled filter. The volume of the filter is too large for the flow rate of the pump. Check your filter’s OEM specs.
5 Porous gas lines
Old gas lines become damaged and porous, and a fuel pump can draw air through the porous lines, reducing its ability to fill the filter. Check all your gas lines, bend them and look for signs of cracks. Also check your line clamps, a vacuum leak at a clamp will have the same effect.
6 Gas tank clogging
A clog in the gas tank can be something as simple as leaves, the gas drains out through a very small opening and becomes easily blocked. You can eliminate a possible cause by removing the gas tank line and checking the flow.
7 Bad fuel cap
A gas tank needs to breathe. Gas leaving the tank must be replaced with air. If this is not the case, the gas stops flowing. This is why gas caps are vented, but they can stick, or a MacGyver-style cap may have been installed. The easiest way to fix this problem quickly is to remove the gas cap, run the engine and check the filter.
8 fuel pump error
Your fuel pump moves gas from the tank to the carburetor bowl. It can be positioned near the gas tank or near the engine. There are two common types, electric and vacuum operated. An electric pump is reliable, but brake pads wear out. The pump normally activates when the ignition is on and that should be enough to fill the filter.
Some pumps may only initiate a start when the bike is cranked. Some pumps are equipped with a check valve to prevent extended cranks associated with fuel spillage. Electric pumps operate audibly and are usually positioned near the gas tank.
Tips for troubleshooting electric dispensers
Locate pump and listen with ignition on and crank cranked
Check power supply connections, fuse and relay
Check ground connection
Hot wire pump – run power and ground to test
Even if your pump is running, it can still be defective. Only a fuel pressure test kit will confirm head pressure.

vacuum fuel pump
A mechanical vacuum pump is a far less complex beast. It uses a diaphragm and scavenges an engine vacuum to power it. A typical pump has a gas line from the gas tank and a gas line to the carburetor fuel tank. These pumps are usually mounted closer to the engine.
A third tube (from the crankcase) is the vacuum supply line that drives the pump.
Troubleshooting a vacuum pump
Locate the pump – usually bolted to the motor
Check the vacuum supply line – often damaged
Check lines for kinks
Removing the pump outlet tube when cranking the engine should allow fuel to flow. Like the electric pump, your vacuum pump can also show signs of life, but it can still be defective. Only a pressure test will confirm this.
Carburetors come in two main varieties, mechanical slide and CV (Constant Velocity) – vacuum operated. The mechanical slide carburetor is the basic type and has always been around.
Closed circuit fuel injection system
The latest, more sophisticated kit uses a fuel injection system, and some emissions compliant kits may use an automotive style closed loop fuel system. This system offers huge advantages in terms of reliability, emissions and self-diagnostics.
An oxygen sensor in the tailpipe measures the fuel mixture ratio, and the on-board computer makes the necessary fuel adjustments, known as fuel trim.
It will usually use:
Fuel pump – supplies the gas
Fuel filter – filters gas filters
Fuel Regulator – Controls the pressure and is often built into the pump
Fuel Pressure Sensors – sends fuel pressure readings to the ECU
Fuel Rail – Pressurized fuel rail tank
Injectors – supply gas to the intake manifold
Temperature Sensor – Provide ECU with engine readings
Air Flow Sensor – provides the ECU with air volume readings
TPS – Throttle Position Sensor
MAP – engine load sensor
O2 Sensor – measures the burned fuel in the exhaust system and sends information to the ECU
ECU – performs all calculations and controls the fuel system
If a fuel injected bike is not filling the fuel filter, there is likely a problem with the electric fuel pump. But the other great advantage of these bikes is their self-diagnostic ability. Check the ECU for trouble codes.
