Installation Guide

1. Ensure the engine is off and cool. Turn off the fuel supply and disconnect the battery.

4. Carefully twist and pull the hoses off the old filter. Note the direction of the fuel flow arrow printed on the filter body.
5. Position the new filter, ensuring the flow arrow points in the correct direction (from the fuel tank, towards the engine).
6. Connect the fuel lines to the new filter and secure them tightly with the provided hose clamps.

8. Prime the fuel system according to your engine manufacturer's procedure. Start the engine and check for leaks again.
