Mercury MerCruiser / Quicksilver Fuel Filter – 8M0093688
Maintain clean fuel delivery and protect your engine with the genuine Mercury Marine / Quicksilver 8M0093688 Water-Separating Fuel Filter. This OEM filter removes water, debris, and fuel contaminants before they reach the engine’s fuel injection system, helping maintain performance and protecting sensitive fuel system components.
Designed to Mercury Marine’s original equipment specifications, this filter installs directly into the Gen III Cool Fuel system used on many MerCruiser sterndrive and inboard engines.
