04.5-10 GM 6.6L Duramax XDP Race Fuel Valve

The XDP Race Fuel Valve prevents fuel from being returned to the tank when the pressure release valve is opened due to fuel rail pressure increases. Many high performance electronic tuning devices raise the fuel rail pressure resulting in P0087 & P1011 codes on Cummins engines and P1093 codes on Duramax engines. XDP now has the solution to this problem without having to use a shim kit.


  • Eliminates Trouble Codes
  • Increases mid-range and top end power
  • Replaces expensive factory pressure relief valve
  • Ability to run higher horsepower tunes
  • Easy Installation

Note: You will reuse the stock o-ring.
