Perko 0635DP0 Inlet Check Valve for Fuel Tank Fill Systems

The Perko 0635DP0 Inlet Check Valve features a patent-pending "In-Pipe ICV" design that revolutionizes fuel tank filling systems for marine applications. Unlike traditional in-line check valves, this innovative valve mounts directly inside standard 1-1/2" fill pipes near the fuel tank connection, eliminating external installation requirements.

Key Features:

• Patent-pending in-pipe design fits inside 1-1/2" fill pipes for seamless installation
• Compatible with both plastic and metal fuel tanks
• Eliminates need for retooling existing doghouse openings on plastic tanks
• Replaces traditional in-line check valves, removing 4 hose clamps and 2 potential leak points
• Maintains full 18 GPM flow rate for fast, efficient fueling
• Reduces installation complexity and improves system reliability

This inlet check valve is designed to prevent fuel backflow while maintaining optimal flow rates, making it an ideal upgrade or replacement component for boat fuel systems. The innovative in-pipe mounting eliminates the bulky external fittings associated with conventional inline valves, resulting in a cleaner, more reliable installation.
