Dmax Swap’s Ported Fuel Rail Fitting replaces the stock fitting to significantly increases fuel rail pressure during heavy engine load applications. This is a high quality stainless steel fitting made to increases available fuel flow volume from the CP3 pump to the fuel rail. This is vital to producing maximum efficient/clean horsepower. We suggest 2 of these fittings for both fuel rails, since the driver side fuel rail feeds the passenger side.
