Failure Symptoms

Initial signs of a failing fuel filter include a slight reduction in engine power or hesitation during acceleration. If ignored, the engine may begin to run rough, misfire, or experience difficulty starting, especially in cold weather. Continued operation with a severely restricted filter can lead to fuel starvation and potential engine shutdown.

Installation Tip

Ensure the fuel tank is at least half full before starting to minimize air entering the fuel system. Do not overtighten the filter housing, as this can damage the seal and cause leaks.

Service Note

Always replace the fuel filter in conjunction with the primary fuel filter (if applicable) and inspect the fuel water separator.
