Attwood Marine 8M0044687 Fuel Demand Valve Assembly, Fuel Shut-Off Valve

The Attwood Marine 8M0044687 is a fuel demand valve assembly, also called a fuel shut-off valve or FDV. It makes sure fuel reaches the engine on demand, not because of pressure built up in the tank. That helps prevent engine flooding and fuel spillage.

Key Features:

• Keeps pressurized fuel from reaching the downstream fuel lines and engine
• Reduces fuel spray when you connect and disconnect fittings at the engine
• Designed for use with 3/8 inch and 5/16 inch fuel hoses
• Compatible with ethanol-blended fuels
• Rated for a nominal input pressure of up to 20 psi, and protected against pressure spikes up to 40 psi
• Built-in manual override
• Flow performance of 125 L/H (33 GPH) at under 2 kPa
• Installs in-line between the fuel tank and the primer bulb or fuel pump

This valve suits portable fuel systems where the tank may build pressure, such as pressure caused by heat. It gives you cleaner fuel connections and helps the engine run properly at startup and in operation.
