The Sierra 118-7776-1 is a complete marine fuel water separator kit designed to protect sensitive fuel injection systems from water contamination and debris. This advanced filtration system removes over 99.8% of emulsified water from gasoline, making it essential protection for inboard, sterndrive, and outboard marine engines.

Key Features:

• 21-micron fuel filter for optimal filtration efficiency
• Flow rate of 90 GPH to support high-performance engines
• Marine-grade stainless steel construction for corrosion resistance
• 3/8" (9.5mm) NPT thread size for easy installation
• Specifically designed for marine environments and ethanol-blended fuels

Kit Includes: Stainless steel fuel water separator bracket, 21-micron tall fuel filter element, and pipe plugs for complete installation.

This filter prevents damage to sensitive inboard, sterndrive, and outboard fuel injection systems by removing water and contaminants before they can cause expensive repairs. The tall filter design provides extended service intervals and superior filtration capacity. Replaces Moeller 33321-10 and Mallory 9-37856.
