Troubleshooting & FAQ

Q: How do I confirm this filter fits my engine?
A: The most reliable method is to match your existing part number to the numbers in our "Part Number Cross-Reference" table. You should also consult the "Compatible Engine Models" tables to verify your specific engine model and year are listed.

Q: My clear filter housing looks yellowed or cloudy. Is it still okay?
A: Discoloration of the clear housing can occur with age and exposure to fuel additives or sunlight. While not always a sign of failure, it's best to replace the filter if you notice it becoming brittle, cracked, or if visibility of the internal filter element is obscured.

Q: How often should I replace my in-line fuel filter?
A: For most recreational boats, it is best practice to replace your fuel filter annually or every 100 hours of operation, whichever comes first. If you experience fuel contamination or operate in harsh conditions, more frequent replacement may be necessary.
