Troubleshooting & FAQ
How can I confirm this filter fits my specific engine model?
While this filter fits a wide range of models, always verify compatibility by checking your service manual for the OEM part number. You can cross-reference it with the numbers in our Part Number Matrix and check the engine compatibility table. Visually comparing your old filter to our product images and specifications is also a good final check.
What are the symptoms of a clogged or failing fuel filter?
Common signs include engine hesitation or sputtering, difficulty starting, reduced power and acceleration, and rough idling. If your engine is experiencing these issues, a blocked fuel filter is a likely cause.
How often should I replace my water-separating fuel filter?
Replacement intervals vary by engine manufacturer and usage conditions (e.g., fuel quality). A general guideline is to replace it annually or every 100 hours of operation, whichever comes first.
What is the benefit of a 10-micron filter?
A 10-micron rating means the filter captures very small contaminants and emulsified water. This provides superior protection for sensitive modern fuel injection systems compared to older 20- or 30-micron filters, preventing injector damage and ensuring optimal engine performance.
Will this filter work with ethanol-blended fuels?
Yes, this filter is constructed with modern materials designed for use with gasoline, including ethanol blends (up to E10). The seals and housing are resistant to the corrosive effects of ethanol.
Can I use this for a 2-stroke outboard?
Yes, it is compatible with many 2-stroke and 4-stroke models requiring this filter type. For pre-mix 2-stroke engines, it correctly functions by filtering fuel and water without separating the 2-cycle oil from the gasoline.
