Sierra Marine Fuel Water Separator Filters

Sierra Marine fuel water separator filters help protect inboard, sterndrive and outboard engines from water, dirt and debris in the fuel supply. Sierra also sells these as marine fuel filters or water-separating fuel filters. They are built for the harsh marine environment and are designed to meet or exceed original equipment specifications.

Key Features:

• Removes water and particulate contaminants before they reach the fuel system
• Micron-rated filtration. The micron rating varies by part number, and the 10 micron filters are over 90% efficient at removing particles as small as 10 micron
• Flows at 90 GPH, enough for high-demand engines
• Helps with ethanol-blended fuel, which absorbs more water and loosens more particulates than regular fuel
• Rugged construction suited to marine use
• Direct-replacement designs for many popular marine engine brands
• Backed by Sierra's customer satisfaction warranty

Sierra has decades of experience making marine engine and drive parts. Proper fuel filtration helps protect fuel injection systems and supports engine performance and longevity. Regular replacement is recommended, such as once a season or during winterization.
