Description

The Sierra 18-7866 is a fuel filter designed to protect your engine from water and debris. It is for use with Yamaha engines and removes over 99.8% of emulsified water from gasoline.

This 10-micron filter is over 90% efficient at removing particles as small as 10 microns and flows at 90 GPH. It is recommended for sensitive inboard and outboard fuel injection systems to prevent damage. The filter features a high-capacity, 6-inch size and an 11/16-16 thread pitch. It is SAE, JIS, and ISO tested and approved, with an epoxy-coated steel canister to prevent corrosion.
