  2. Place a rag or container under the existing filter to catch any spilled fuel.
  3. Loosen the clamps securing the fuel hoses to the old filter and carefully disconnect them.
  4. Note the direction of the fuel flow arrow on the new filter. It must point towards the engine.
  5. Connect the fuel lines to the correct inlet and outlet ports on the new filter.
  6. Secure the hoses firmly with clamps. Ensure they are snug to prevent leaks.
  7. Turn the fuel supply back on and prime the engine if necessary.
  8. Start the engine and carefully inspect the filter and connections for any signs of fuel leakage.

Troubleshooting & FAQ

How do I confirm this filter fits my specific engine model?

First, check the Engine & Model Compatibility table on this page. Second, and most importantly, compare your original part number to those listed in our Part Number Matrix. If your number matches, the fit is confirmed.

What is the correct way to install the filter?

The filter must be installed in the correct direction to function properly. Look for an arrow printed on the filter's body. This arrow must point in the direction of fuel flow, which is from your fuel tank towards your engine.

How often should this fuel filter be replaced?

For optimal engine protection and performance, it is recommended to replace the inline fuel filter annually or every 100 hours of operation, whichever comes first. Change it more frequently if you operate in harsh conditions or use fuel of questionable quality.

What are common signs that my fuel filter is clogged or failing?

A failing filter may cause symptoms like the engine bogging down under acceleration, difficulty starting, rough or unstable idling, a noticeable loss of power, or stalling. Visual inspection of the transparent body may also show accumulated debris.
