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.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
