Sierra 18-7865 Fuel Water Separator Filter, 10 Micron, Yamaha Outboard OEM Equivalent MAR-MINIF-IL-TR

The Sierra 18-7865 is a 10 micron fuel water separator filter element built for outboard fuel systems, with a stainless steel outer housing that stands up to marine environments. It is designed to protect the engine from water contamination and debris in ethanol-blended fuel, which absorbs more water and loosens more particulate than non-blended gasoline. Proper filtration ahead of the carburetor or fuel injection system helps keep the fuel supply clean regardless of horsepower.

The filter media is rated 10 micron and is over 90 percent efficient at removing particles as small as 10 microns, while the fuel water separator function pulls emulsified water out of the fuel before it reaches the engine. Rated to flow at 90 GPH, the 18-7865 is sized to keep up with demand on the fuel system without restricting supply. It carries an OEM equivalent cross-reference to the Yamaha outboard filter MAR-MINIF-IL-TR, and is compatible with Yamaha outboard motors. The filter is also used as the filter element in Sierra fuel water separator kits alongside a mounting bracket, which is sold under its own separate part number.
