Troubleshooting & FAQ
How do I know if this fuel filter fits my engine?
This filter is designed for most Johnson/Evinrude/OMC outboard motors that use a 3/8" ID fuel hose. The most reliable method is to verify your engine's required part number. This part cross-references with OEM numbers 5005266, 5007326, 5007335, and Sierra aftermarket number 18-7722.
What is the correct installation direction for the filter?
Inline fuel filters are directional. An arrow is typically printed or molded onto the filter's housing to indicate the direction of fuel flow. This arrow must point towards the engine for correct installation and filtration.
What are the signs of a clogged or failing fuel filter?
Common symptoms include the engine hesitating, sputtering, losing power especially at high speeds, having difficulty starting, or stalling at idle. If you experience these issues, a restricted fuel filter is a likely cause.
How often should I replace my outboard fuel filter?
As a best practice, replace your fuel filter annually or every 100 hours of operation, whichever occurs first. This interval can vary based on fuel quality and usage, so consult your engine’s service manual for specific recommendations.
Is this a direct replacement for Sierra part 18-7722?
Yes, this fuel filter is a direct aftermarket replacement for the Sierra Marine 18-7722 filter.
