The Duramax Ported Fuel Rail Fitting is for your 2004.5-2010 Chevy/GMC Duramax with the LLY/LBZ/LMM motor. PPE’s Ported Fuel Rail Fitting replaces the restrictive stock fitting and helps maintain fuel rail pressure during heavy engine load applications.

This high quality stainless steel fitting increases available fuel flow volume from the CP3 pump to the fuel rail. Adequate fuel flow is vital to producing maximum efficient/clean horsepower. These fittings benefit both fuel rails, since the driver side fuel rail feeds the passenger side.


  • Reduces fuel pressure drops that are caused by the restriction of the stock fuel rail fitting
  • One or two fittings can be used simultaneously in left and right fuel rail
