Our r12t fuel water separator element uses advanced hydrophobic media that separates and captures water droplets while allowing clean fuel to pass through protecting your injectors, fuel pump, and combustion chamber. Each filter is individually tested and backed by our satisfaction guarantee. Frequently Asked Questions Q: How often should I replace my marine fuel water separator? A: We recommend replacing your fuel water separator every 100 hours of operation or once per season, whichever comes first. If you notice reduced engine performance, difficulty starting, or water in your fuel filter bowl, replace immediately. Q: Will this fit my Mercury outboard? A: Yes. This filter fits standard marine fuel water separator heads with 1/4" NPT (ZG1/4-19) threads, compatible with all Mercury outboard engines from 4HP to 300HP when used with the appropriate filter head. Q: What's the difference between 10-micron and 30-micron filters? A: 10-micron filters capture finer particles and provide better protection for modern fuel-injected engines. If you have a carbureted older outboard, 30-micron may be sufficient, but for EFI/DFI engines, 10-micron is strongly recommended. Q: Can I use this filter with ethanol-blended fuel (E10)? A: Yes. Our filter media is compatible with ethanol-blended fuels up to E10. However, ethanol can accelerate water absorption, so more frequent filter changes may be needed if you use ethanol fuel regularly. Q: How do I know when the filter needs replacement? A: Signs include engine hesitation at high RPM, difficulty reaching full throttle, rough idle, or a visible water layer in the clear bowl (if equipped). Always carry a spare filter on board. Q: Is this filter USCG compliant? A: Yes. Our fuel water separators meet USCG and ABYC standards for marine fuel system components. Related Pro
