Fuel Filters

About Fuel Filters

A fuel filter catches dirt, rust and debris before it reaches the carburetor or injectors. Riders replace one at a service interval, when a bike hesitates or starves for fuel, or when they add a clear filter to see what is in the line.

Listings include inline filters sized 1/4 inch and 5/16 inch, fuel tank filters, an anodized aluminum filter, a high-flow filter and a filter kit for Beta, Husqvarna, KTM and Gas Gas TPI models. The inline size should match the inside diameter of your fuel line, and tank filters are made for specific tanks, so pick by your model. Fit it with the arrow, if there is one, pointing in the direction of fuel flow, and use proper clamps. After fitting, check for leaks and keep gasoline away from sparks and flames.

Brands here include Helix, HardDrive, Drag Specialties, WSM and Acerbis. Nearby parts are Fuel Hoses, Lines & Pipes, Fuel Petcocks & Taps, Fuel Pumps & Sending Units and Fuel Tanks. Pick your bike in the Ride Finder at the top of the page.

FAQs on motorcycle fuel filters

How do I match a fuel filter to my fuel line?

Measure the inside diameter of your fuel line, or check your manual, and choose a filter with fittings in that size, such as 1/4 inch or 5/16 inch. Using the wrong size forces you to use adapters or clamps, which can leak.

Which way does an inline fuel filter go?

Most inline filters have an arrow showing the direction of flow, which should point toward the engine, away from the tank. If yours has no arrow, follow the maker's instructions. A filter fitted backward can restrict flow or release trapped dirt.

Where is the fuel filter on my motorcycle?

It depends on the model. Some bikes have an inline filter in the hose between the tank and engine, and others have a filter inside the tank, on the petcock or on the fuel pump. Your service manual shows where yours is and how often to change it.

What are signs of a clogged fuel filter?

Hesitation under load, hard starting and loss of power at high speed can point to a clogged filter. Other problems cause the same symptoms, so check the filter, the petcock and the fuel as part of the diagnosis.

Can a fuel-injected bike use any of these filters?

Not just any of them. Fuel-injected bikes run at higher pressure than carbureted bikes, so use the filter listed for your model, and do not fit a filter that is not rated for the pressure and clamps of your system.
