Sierra 18-7865 marine fuel filter. Ethanol blended fuel absorbs more water and loosens more particulants than regular fuels. Proper filtration is required for every horsepower engine. Sierra fuel water separators remove over 98.8% of emulsified water from your gasoline. Sierra’s 10 micron filters are over 90% efficient at removing particles as small as 10 micron. All filters flow at 90 GPH to feed even the hungriest motor. Rating: 10 Micron. Replaces: Mallory 9-37808, Yamaha Outboard MAR-MINIF-IL-TR.
