Fuel Filters
About Fuel Filters
A fuel filter stops rust, dirt and debris in the tank from reaching the carburetor or injectors, where even small particles can block a jet or damage a pump. Owners replace one when an engine hesitates under load, stalls, or loses power, or as part of a regular service.
Fit and flow are the two choices. In-line filters connect in the hose and are sized by the hose they join, with listings from small sizes such as 1/8 to 3/16 inch up to 1/4, 5/16 and 1/2 inch, and the size must match your fuel line. High-flow and high-capacity versions are made for engines that need more fuel.
Others, like the in-tank filters and the fuel pump strainers listed here, sit in the tank or on the pump of a fuel-injected machine and are matched by model. In-line filters have a flow direction, so fit them the way the arrow points. Fuel is flammable: work outdoors, away from flames, with the engine cool and the machine off.

FAQs on UTV and ATV fuel filters
How do I choose the right size fuel filter?
Match the filter's fitting size to the inside diameter of your fuel line, which is listed in inches, such as 1/4 or 5/16. Check your hose size or the old filter. A filter that does not match the hose will not seal, so use the listing's size and your machine's year.
Which way does a fuel filter go?
An in-line fuel filter usually has an arrow showing the direction of flow, and the arrow should point toward the carburetor or fuel pump inlet, away from the tank. Fit it the way the arrow points, and check the connections for leaks.
What is the difference between an in-line and an in-tank filter?
An in-line filter sits in the fuel hose between the tank and the engine and is easy to reach. An in-tank filter or pump strainer is fitted inside the tank, often on the pump of a fuel-injected machine, and is matched to a model. Which you need depends on your machine.
Is it safe to change a fuel filter on a fuel-injected machine?
It can be, but fuel-injected systems hold pressure after the engine stops. Follow the manual's procedure to relieve it, work in a ventilated area away from flames, and catch spilled fuel. If you are unsure, have a shop do the job.
When should I replace a fuel filter?
Follow the interval in your owner's manual, and replace it earlier if the engine hesitates, loses power under load or the filter looks dirty or blocked. Fuel from poor-quality or old storage can clog filters sooner.
