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.

CFR 40 1060.105 (c)
Effective January 1, 2010 – Portable marine fuel tanks and associated fuel-system components must meet the following requirements:
1 They 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.
2 They 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).
