Sierra Water Separating Fuel Filter 18-79969

The Sierra 18-79969 is a water separating fuel filter designed to protect your marine engine's fuel system by removing water and contaminants from fuel before they reach the carburetor or fuel injection system. Water and debris in marine fuel are common problems caused by condensation in fuel tanks and the ethanol blends found in many pump gasolines, and an inline water separating filter catches these contaminants before they can cause hard starting, rough running, or corrosion inside the engine. This filter is sold as a single unit and is built for straightforward installation into an existing water separating fuel filter housing or assembly. Keeping a spare on hand and replacing the filter element on a regular maintenance schedule helps prevent fuel-related engine problems and keeps a marine fuel system running reliably season after season. As a Sierra branded part, it is manufactured to work as a direct replacement filter for water separating fuel filter systems that use this filter specification.
