PPE’s Ported Fuel Rail Fitting replaces the restrictive stock fitting. Our fitting increases fuel flow volume from the CP3 pump to the fuel rail simply by making the whole bigger. Adequate fuel flow is vital to producing maximum horsepower. With the increased flow, the Ported Fuel Rail Fitting, is recommended for both high performance and race applications. 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
* Driver side required, additional passenger side strongly recommended for race or Dual Fueler applications
