Installation Guide

1. Locate the existing inline fuel filter. It is situated in the fuel line between the low-pressure fuel pump and the Vapor Separator Tank (VST).
2. Place absorbent rags or a container beneath the filter to catch any fuel that may spill during removal.
3. Carefully cut or release the clamps or zip ties that secure the fuel lines to both ends of the old filter.
4. Gently twist and pull the fuel lines off the old filter. Be prepared for minor fuel leakage.
5. Note the fuel flow direction, which is typically indicated by an arrow on the filter housing.
6. Install the new filter, ensuring the arrow points toward the VST, maintaining the correct direction of fuel flow.
7. Secure the fuel lines onto the new filter barbs using new, appropriately sized hose clamps or fuel-line-rated zip ties to ensure a tight seal.
8. Before starting the engine, prime the fuel system using the primer bulb until firm. Carefully inspect the filter and connections for any signs of leaks.
