Fuel Demand Valve
The fuel demand valve, used in conjunction with portable fuel systems, is for above deck use only, 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. Provides solution for managing pressurized fuel lines and tanks that are required due to EPA regulatory requirements for portable fuel system evaporative emission controls.

  • 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 engine functionality issues created by pressurized fuel lines
  • Eliminates fuel spill due to pressurized fuel tanks and fuel lines
  • Available individually or as part of a fuel line assembly
  • Required on Attwood EPA Certified/New Regulation Compliant fuel tanks. Not required on older tanks.

Problem Solver
by Andrew from Brandon, Mississippi on November 26, 2012
I could not figure out why my emgine would quit until I realized it was being flooded by overpressuer from fuel tanks as the heated during the day. After installing this valve, no more problems. Easy to install.

Great addition to upgraded fuel systems!
by Scott from Mexico, New York on July 24, 2014
Completely upgraded my fuel tanks and lines to handle modern ethanol fuel, and this little gem was the finishing touch. Prevents fuel under pressure from being forced out of your new EPA compliant fuel tank (modern fuel tanks must hold at least 5 psi to prevent fuel vapor loss) and into your carb bowl, flooding your engine while it sits and isn't running. Only allows fuel to flow to engine if engine demands it (suction from engine fuel pump, or primer bulb). Easy install, cut fuel line 6" upstream from tank fitting (installs between tank fitting and primer bulb, primer bulb suction causes FDV to allow fuel to flow from tank),slide a clamp over each end of your fuel line, push fuel line onto each barb (pay attention to fuel flow direction arrow on valve!) tighten clamps and your done! 10 minute job tops. I can say this much, my engine did not flood and started easily over the course of an afternoon fishing on Lake Ontario in 90 degree summer sun.

Worked as advertised.
by Joseph from Porter, Indiana on July 07, 2013
No issues. The product worked as advertised. Though I cannot say if the tanks worked without this in the fuel line.
