Attwood 8M0044687 Attwood’s Fuel Demand Valve FDV provides a unique, Inlet, CFR 40 1060.105 c

FUEL DEMAND VALVE

Attwood’s Fuel Demand Valve (FDV) provides a unique

solution for managing pressurized fuel lines and fuel tanks that are required due to EPA regulatory requirements for portable fuel system evaporative emission controls. The Fuel Demand Valve eliminates pressurized fuel from reaching downstream fuel lines and your engine, ensuring that fuel is

provided to the engine on demand rather than as a result of pressure in the tank.

•Installs in-line between your fuel tank and primer bulb/fuel pump

•Eliminates fuel fitting spray when connecting and disconnecting fittings at the engine

•Eliminates fuel spill due to pressurized fuel tanks and fuel lines

•Pad printable: Customizable with your company logo

•Eliminates potential service and warranty issues related to pressurized fuel lines

•Available individually or as part of a fuel line assembly

CFR 40 1060.105 (c)

Effective January 1, 2010 – Portable marine fuel tanks and associated fuel-system components must meet the following requirements:

1They must be self-sealing (without any manual vents) when not attached to the engines. The tanks may not vent to the atmosphere when attached to an engine.

2They must remain sealed up to a positive pressure of 24.5 kPa (3.5 psig); however, they may contain air inlets that open when there is a vacuum pressure inside the tank. Such fuel tanks may not contain air outlets that vent to the atmosphere at pressures below 34.5 kPa (5.0 psig).
