Add inline fuel filter okay for small push mower. Honda lawnmower fuel filter
Add inline fuel filter okay for small push mower?
just wondering before I cut the fuel line and put an inline filter. Maybe it will slow down the flow of gas to the carb and create problems? Or does the pressure remain the same even with the filter or it doesn’t matter?
apparently okay for small push mowers, just making sure.
For probably 25 cents each in bulk, then I don’t know why manufacturers aren’t putting these on all mowers adn even trimmers and blowers, maybe they want people to have dirty carbs and need to buy replacement carb and carb kits?

Whatever brand filter you use, ensure that it is aplicable for an engine tbat does not have a fuel pump. The filters used on engines without fuel pumps filter to 75 micros or more where engines that have a fuel pump can tolerate filters as low as 40 microns. Using a filter for an engine with a fuel pump in an engine without a fuel pump will cause fuel delivery issues.

Look, most all poly tanked mower motors have a plastic/nylon screen molded in the tank at the outlet. Really no need to add a filter.

You do realize that all trimmers, blowers etc. have fuel filters attached to the end of the fuel line in the tank, right? Sheesh.

Trimmers and blowers have them but the flow of fuel through the filter would be slowed down too much for the carb.
I’ve experimented with this before on a roto tiller and it was having fuel starvation issues. This was a briggs and stratton industrial plus 5hp motor.
Short answer the original question, no I wouldn’t recommend it. Another poster said that they have a screen in the fuel tank.

We have these on many of our small engines with no fuel delivery issues. They have a screen built inside. There is no paper elememt. They are basicly an external screen just like what Big Fish said in integrated into the tank.
roody2333
yeah I know duh, I have like 10 spares, trimmers/blowers etc have filters in the tank.
good info eric on using one made for pumped fuel vs just gravity-fed. And, big fish, I just learned screens are built into the fuel tank port. I think I will add filters anyway. I don’t think the one in the tank filters as finely because it’s not replaceable.
I was thinking on the same track as this guy before I found these videos.
Basically, he was stalling out at half a tank and thought the inline filter was depriving the carb with a small capacity tank (my 36″ bobcat has an inline and no fuel pump but it holds like a gallon, but when it gets low, it essentially becomes a ‘small’ tank I guess with little pressure unless maybe all the extra empty air forces the gas down or the design on the hole in the gas cap allows more air through). So he took out the inlien filter and put in a new gas line without the filter. But then he cleaned the carb and found some debris, so he put the inline back in and it runs fine.

No, amazingly enough most 3.75. 10 HP engine powered machines do not sport actual fuel filters. Most do have a screen inside the tank but that will only stop bigger things such as grains of sand, it will not stop small pieces the size of say a speck of pollen from floating down stream and that’s just enough to clog up a jet.
I have for some years now added fuel filters inline to these machines. I have not had a problem with fuel flow in that regard, fuel filters are designed with this in mind. It saves my carburetors.
You do need to be careful where exactly to place it so that it doesn’t interfere with throttle mechanisms and also so that it doesn’t touch the engine itself. It takes some tinkering to find the right spot for it, remembering that you can always cut off more fuel line but once it’s cut you can’t put it back on. I usually have spare fuel line around just in case.

Anyone know how to determine correct in/out of the filters.if no arrow mark.? And how do we know when a inline paper filter is built for fuel pump or gravity system.

The cone shape of the filter points towards the fuel tank. They’re all paper filters.
Steel casing filters are usually made for EFI
ericg
Be careful. here is a Kohler OEM paper filter for use only on engines with mechanical fuel pumps. https://www.kohler-engine-parts.ope. ystem/fuel-filters/kohler-fuel-filter-2505022 I guess the best way to know if a paper filter is for gravity feed or fuel pump is to look at the original packaging or cross reference the part number. These filters are generally good to 30psi. As Herler stated, once you get in to the higher pressure EFI systems, the filters are steel.
ericg
Fuel filters for use with mechanical pumps trap dirt as small as 50 microns. If this type of filter was put in a gravity fed fuel system, there would be fuel delivery issues after the filter became partially clogged.

If no arrow, it should be orientated the same as ones with arrows. If you check ebay, you should be able to get a zoomed-in image that shows the arrow just to use a reference (I’m not assuming you’ll buy them on ebay, you apparently already have it). Basically, the filter paper sometimes sort of comes to a point on one end and on the other it’s more of a round disc that is the same diameter of the plastic housing (one end is wider diamater). From what I’ve seen, the larger diameter side of the paper filter is the side that goes furthest from the gas tank. If it’s not a clear housing filter, or you can’t open it, then I don’t know. Sometimes the paper is perfectly cylindrical but will be attached to one side of the plastic housing and the other side has some empty space inside the plastic housing. The side with the space is going to be the side that the fuel comes in. Here’s an example image of the non-tapered kind. The bottom (see that space) is where the gas comes in. The arrow says To Carb on it.
How to Avoid Honda Lawnmower Fuel-Related Issues
Make sure that you store the gas you plan on using in a sealed plastic container that has been approved for storing fuel and is clean.
Keep your Honda lawnmower running smoothly by following some simple maintenance tips and general advice about how to use it. Honda lawnmowers are built to last, but fuel-related issues can occur if you aren’t careful. That is because gasoline’s properties mean that stale fuel can cause problems running or starting. To avoid these problems, follow these tips.
Choose the Right Gasoline
When picking the gasoline to put in your Honda lawnmower, make sure that it has 10 percent ethanol or less. Higher quantities of ethanol will attract water and be corrosive, leading to issues running or starting as well as possible damage to the fuel system.
Store Gas Correctly
Storage is crucial for preventing fuel-related problems. Make sure that you store the gas you plan on using in a sealed plastic container that has been approved for storing fuel and is clean. Keep the fuel away from direct sunlight and add a stabilizer if you will need over three months to finish the container of fuel. This will prevent metallic contaminants and rust and reduce the rate of deterioration.
Stow the Mower Correctly
After you finish mowing, put the fuel valve to OFF, leaving it there until the next time you mow. Fill up your fuel tank, as this minimizes air and the fuel deterioration caused by it. If you won’t be using your Honda lawnmower for another 3 or 4 weeks, be sure to leave the fuel valve OFF when starting the engine. Let it run until there is no more gas.
If you will be storing the mower for between 30 and 90 days, be sure to add a stabilizer to your fuel. After doing so, run the engine outside for 10 minutes, as this makes sure the treated gas goes through the system. You can skip that step if you frequently add stabilizer. Remember to stop your engine and move the fuel valve to OFF. If you won’t use the mower for over 90 days, let the engine run for enough time to completely empty the gas from the fuel system and tank. You should never let gas stay in your lawnmower if it will be inactive for 90 days or more.
Service the Air Filter
Ensuring that your lawnmower’s air filter is maintained properly prevents dirt from getting into the carburetor. Any time that you will be using the lawnmower, check the air filter first. If you use the mower in dusty areas, replace the filter frequently, and always use Honda Genuine air filters.
Now that you know how to prevent fuel-related problems in your Honda lawnmower, you are ready to pick out the right mower for your needs. Brannon Honda in Birmingham, Alabama, has a wide selection of Honda lawnmowers and other power equipment.

Should a lawn Mower fuel filter be full?
You should realize optimal performance with a good lawnmower from a reputed manufacturer like John Deere, Kohler, and Briggs Stratton. Most importantly, knowing how every part of your machine functions will keep you in the know should there be faulty components. Let’s take, for example, the lawnmower fuel filter-which is the subject of this post. A filter purifies fuel before it goes into the combustion chamber. Thus, ensuring it is always in perfect health is crucial.
Should a lawn Mower fuel filter be full?
Yes, a lawnmower fuel filter should be full. Lack of enough fuel in the filter will hamper the performance and is bad for its health. Lawnmower filters that do not fill up with fuel often signal a problem.
A faulty filter has a direct impact on the functionality of your lawnmower. And it is always a case of dirt and impurities getting into the combustion chamber. Such is a problem that will render your machine less effective. Even worse, a decrease in performance due to clogged gas filters will result in engine ignition problems. As a result, homestead craftsmen do many other questions. For example, why is fuel not filling up my lawnmower filter? How do clean clogged lawn mower gas? Do I need to replace the filter with a new one? How often should you clean the filter?
Change the Fuel Filter on a Mower
Why should a lawn mower fuel filter be full?
The next question which you are probably asking is why should the filter be full of gas? Well, when there isn’t enough fuel going through this component, your mowing tractor may start to stall out. You must have heard about mowers that have ground to a halt midway when cutting grass uphill or those that fail to start completely. Such is a situation that signals a lack of enough fuel in the combustion chamber.
When the filter is clogged with dirt, not enough fuel goes through. Your machine may start but stalling incidences become commonplace. The catch here is that there should be surplus gas going through the filter so that the engine does not get deprived at some point. Make sure to check the filter for any defects as soon as your lawnmower starts to stall out. If the filter is not clogged upon examination, chances are high that the fuel line is the problem.
Cleaning lawn mower fuel filter
Fuel filters that do not fill up are easy to detect. It only takes a few easy steps of inspection. You should also note that because filters prevent dirt from getting into the engine, leaving them unattended can render your mower less or completely inefficient. The engines could get damaged, and that means costlier maintenance and repair. You, therefore, would not want to wait until it is too late to clean clogged filters.
Before cleaning the filter, find out if it is paper/nylon or metallic. While metallic filters are easy to clean, you may have to replace paper ones-ostensibly the best advice any experienced homesteader would give. Steps to cleaning metallic filters include:
Step 1: Relieve fuel lines of pressure
Start by relieving the fuel system of pressure. To do this, locate the fuel pump fuse, remove it then run the engine for at least two minutes. Provided you have parked the mower in the open air, everything should work out fine.
Step 2: Remove the spark plug
Disconnect the battery terminals. We advise that you disconnect the negative one. It helps prevent a fire hazard that may result from the ignition of gas fumes in the fuel system. This is a good time to check your sparkplug, clean them, or replace them if needed. Here you can find spark plugs.
Step 3: Disconnect the fuel lines
Remove fuel lines connecting to the filter with the combustion chamber. A crew wrench should help you perform the task with great ease. You should wear protective clothing, including eyewear when removing fuel lines.
Step 4: Remove fuel filter
Now detach the filter from its seating. Always remember to check its placement so that you don’t have challenges during reinstallation. You should, however, note that some filters, if not most, have arrow inscriptions indicating the direction of installation. If that’s the case with the one on your lawnmower, you reinstalling so that everything is in line with the direction of fuel flow should take only a few minutes.
Step 5: Drain fuel residue and debris from the filter
Drain the filter of any gas/fuel residue by gently tapping it on both ends. When tapping fuel-in and fuel-out nozzles, make sure to drain the remaining fuel into a container.
Step 6: The cleaning stage: Use an ideal cleaner for the carburetor
The next step is cleaning, so you ask-how do you clean fuel filters. We assume that at this stage, you should have a carburetor cleaner ready. Spray it inside and outside the filter. Finally, tap the filter on both ends to drain it off-gas/fuel residue one more time then leave it to dry in the open air for at least an hour. Here you can find some good carburetor cleaners.
Staying safe when cleaning or replacing lawn mower fuel filter
Always remember to unplug the spark plug when carrying out a maintenance or repair routine. You would be risking your life with the plug on should the engine ignite accidentally. If you are not comfortable with cleaning or replacing filters at home, a reputable dealer should help you do it. We advise that you consult none other than a dealer who sold you the machine for the best filter servicing. You would rather spend a few bucks on hiring a professional to do the work than risk shortening the lifespan of your lawnmower.
Do I need to replace the filter with a new one?
With the above steps on how to clean clogged lawn mower gas filters, you should have it back to optimal functioning. However, should it not get filled with fuel once you run the engine; chances are high the damage is beyond cleaning and repair. So, you would want to ask, do I need to replace a filter with a new one?
Well, you don’t have to replace a metallic filter every time it gets clogged, unless it has outlived its usefulness. However, you should replace nylon or paper filters as soon as they become clogged. The process of replacing the faulty filter is rather easy because you only need to remove it and plug a new one in its place. Cleaning paper filters, experienced homesteaders note, may cause more damage and harm, making them less effective.
How often should you clean the filter?
Another major concern among homesteaders is to do with the frequency of cleaning lawn mower fuel filters. They often ask, should I clean the filter after every use or it should be seasonal? Let’s face it. You will not be mowing turf in your backyard every day or week. Sometimes it may take up to a month or two before mowing down overgrown grass in your compound. With that, you should already have an answer to how often one should clean fuel filters.
For starters, you should note that the frequency of cleaning lawn mower gas filters varies from one machine model to another. According to John Deere, a leading manufacturer of lawnmowers, homesteaders should change fuel filters after fifty hours of use. We translate that to mean changing filters at least once every other season of mowing.
Some manufacturers determine the frequency of cleaning or changing filters based on mileage. Thus, based on our research, you can also clean or change filters in your lawnmower with every ten-thousand to twenty-thousand mileage.
The good news with respected brands is that mowing machines come with user manuals that take you through steps to changing and cleaning fuel filters. You can also reach your dealer through a helpline and get help with troubleshooting problems with filters.
No fuel in fuel filter riding mower
If your fuel filter is not staying full while running a lawnmower for several minutes, it can be due to several reasons:
- Clogged fuel line: The fuel line between the gas tank and the fuel filter can be clogged. Remove the fuel line and check if it is free. Replace the fuel line if you are unsure.
- Wrong fuel filter: If you use the wrong fuel filter, it can lead to an empty fuel filter after some time. Check the fuel filter, and replace it if it is not the correct one.
- Gas Gap: Run the engine with the gas cap off for a while. If that fixes the problem, the air hole in the gas gap is clogged. Try to clear it, or drill an additional hole so air can enter the gas tank.
- Vapor lock: Use the following trick to fix the vapor lock. Pour some cold water over the fuel lines and fuel pump when the engine is off. This should cool down the gas quickly, and condense it.
- Fuel valve: Check that the fuel valve is fully opened.
- Fuel pump: If your lawnmower uses a fuel pump, check that it works well.
Final Thoughts
Troubleshooting lawn mower filters for any damage or clogging is an important step toward ensuring the effectiveness and efficiency of the machine. In this post, you have learned that a mower’s filter should be full so that the engine does not misfire. With a filled-up filter, you also are assured of optimal performance-no debris blocking fuel from entering and exiting it.
over, depending on whether you have a Briggs Stratton lawnmower or a Honda Harmony, procedures for determining fuel volume often vary. Lack of enough fuel in the filter has always been cited as the leading cause of stalls, especially when the load is heavy. When exhaust pipes release heavy black smoke and a lawnmower becomes noisy, that’s another sign that you should check the filter. Half-full filters mean clogging, something that poses a bigger risk to the engine’s health.
Signs of a Bad Lawn Mower Fuel Filter
If you’ve ever had issues with the HVAC system in your home, the maintenance guy probably lectured you on the importance of changing the filter regularly; changing a lawnmower fuel filter is just as important to the life and efficiency of your most important piece of lawn equipment — the lawnmower. Knowing what a mower fuel filter is, where it’s located, its job, and the importance of maintenance helps you get the most quality and longevity out of this relatively expensive yard tool.
What is a Fuel Filter?
The fuel filter of a lawnmower is a little piece of equipment that has a big job. It’s usually located in the fuel line or fuel tank of your mower. It has a round filter that is encased in a plastic or metal body and it’s relatively small. You can find a replacement filter wherever you purchased your lawnmower, at a discount center, at the manufacturer’s website or other another online store.

What is the Fuel Filter’s Job?
The lawnmower fuel filter’s job is to prevent foreign materials — like water and debris — from entering the combustion chamber of your lawnmower. It strains the impurities from the fuel before it enters the carburetor. If the filter gets clogged, you will likely encounter issues with your lawnmower. This can be something as simple as an annoying sputter when you try to start the mower, difficulty getting it started, or it can cause the mower to idle unevenly. serious issues include a lack of power when you are mowing, or the lawnmower won’t start at all.
Once you start having these issues from a clogged fuel filter, it affects the way the machine runs, and if it isn’t corrected could cause long-term damage. This may cost more to repair than a brand new lawnmower. A new, well-maintained lawnmower should last you approximately 8 to 10 years, depending on the size of your yard, and the frequency of use. The key to getting the most out of any small engine or lawn tool is to maintain it properly.
The Importance of a Well-Maintained Lawnmower
A lawnmower is probably the most expensive lawn tool you’ll purchase and it should give you many years of quality performance. Many mowers come with a service agreement and if you take it in for service regularly, you’ll be able to get your money’s worth out of the small engine. After the service agreement runs out you can renew it, or you can maintain the lawnmower on your own if you are a do-it-yourself type of person.
Proper maintenance adds years to your lawnmower, keeps it running smoothly, and prevents you from having to struggle unnecessarily while starting it, or pushing the mower across your lawn. Make it a goal to replace the lawnmower fuel filter after about 200 hours of use.
Always refer to the owner’s manual before performing maintenance on the mower. Disconnect the spark plug first before beginning any type of maintenance on the machine. This prevents the mower from starting accidentally, which could cause a major injury. If you don’t feel comfortable changing the fuel filter or doing other types of maintenance on your mower, take it to the dealer where you purchased it, or to a place that works on small engines. The minimal cost of the repair helps ensure that the mower lasts you for several years by running efficiently and doing a quality job on your lawn.
