Mercury Water Separator Fuel Filter - 8M0166596

Mercury Water Separator Fuel Filter - 8M0166596 This water separator fuel filter is designed to provide superior protection for Mercury outboard engines and MerCruiser inboard engines by separating water and contaminants from the fuel system. This is a crucial component for maintaining engine performance and longevity, especially in marine environments where water contamination is a common issue. Replacing a water separator is crucial because it prevents water from entering the fuel system, which can significantly damage the engine by causing corrosion and hindering performance.
