Installation Guide

1. Safety First: Ensure the engine is off and cool. Shut off the fuel supply valve and work in a well-ventilated area.
2. Locate Filter: Find the existing in-line fuel filter. It is typically situated between the fuel tank and the engine.
3. Prepare for Removal: Place a rag or small container under the filter to catch any fuel that may spill.
4. Remove Hoses: Loosen the clamps securing the fuel hoses to both ends of the old filter. Gently twist and pull the hoses off the filter fittings.
5. Install New Filter: Note the fuel flow arrow on the new filter. The arrow must point in the direction of fuel flow (towards the engine).
6. Secure Hoses: Attach the fuel hoses to the new filter and tighten the clamps securely. Do not overtighten.
7. Check for Leaks: Turn the fuel supply back on. Prime the fuel system if necessary and carefully inspect the filter and connections for any leaks.
