PPE Ported Fuel Rail Fitting 04.5-10 Duramax
PPE’s Ported Fuel Rail Fitting replaces the restrictive stock fitting. Our fitting increases available 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 efficient/clean horsepower. These fittings benefit both fuel rails, since the driver side fuel rail feeds the passenger side.
