iFJF Fuel/Water Separator Kit 10-Micron Replacement for Mercury — 90 GPH Flow, 90%+ Efficiency

The iFJF 802893Q01 fuel/water separator kit is a direct-fit 10-micron replacement designed to protect Mercury inboard, sterndrive and outboard fuel systems by removing water and particles while maintaining high flow.

This replacement kit provides a budget-friendly way to maintain fuel system reliability without sacrificing flow. Built to match common Mercury part numbers, the cartridge filters down to 10 microns with over 90% efficiency and supports up to 90 gallons per hour (GPH) to keep engines fed even under demanding throttle. The kit is intended for routine maintenance and to prevent contaminants from reaching sensitive fuel injectors, pumps and carburetors.

How effective is this separator at removing water and debris?

The 10-micron media captures particles and helps coalesce free water, delivering over 90% efficiency at the 10-micron level. While it reduces contaminant load it is not a substitute for professional fuel testing when severe contamination is suspected.

• 10-micron filtration rating for fines and sediment
• High-efficiency media removes over 90% of 10-micron particles
• Designed to separate free water from fuel before it reaches the engine

Will this fit my Mercury engine and replace OEM parts?

The kit is made to replace multiple Mercury part numbers and common equivalents, making it a convenient OEM alternative. Confirm compatibility with your engine model and the listed replacement numbers to ensure a direct fit without modification.

• Replaces Mercury: 35-807172, 35-60494-1, 35-802893Q01 and others
• Fits many inboard, sterndrive and outboard applications designed for these parts
• Direct-replacement design for straightforward installation on compatible housings

How does this filter affect engine performance and fuel flow?

Constructed to allow up to 90 GPH of flow, the separator maintains sufficient fuel delivery for most recreational and performance marine engines. Proper filtration keeps injectors and pumps cleaner, which helps sustain consistent performance over time.

• Flows up to 90 gallons per hour to supply demanding engines
• Protects fuel injection components from abrasive wear and clogging
• Helps maintain steady throttle response by preventing fuel starvation from debris

What should I know before installing the kit?

Installation is generally straightforward, but the filter must be tightened by hand per the manufacturer’s note to ensure proper sealing. Replace the cartridge at recommended service intervals and inspect fuel lines and clamps while the system is open.

• Hand-tighten the filter during installation as instructed
• Check seals and O-rings for wear and replace if necessary
• Drain and inspect separated water frequently during initial service checks

Who is this for: Boaters and marine technicians seeking an affordable, high-flow replacement filter compatible with many Mercury fuel systems. This kit is suitable for owners who perform routine maintenance and want a reliable 10-micron separator to reduce water and particle contamination in fuel systems on inboards, sterndrives and outboards. If you need exact fitment, match the part numbers listed before purchase.
