S&S Diesel Motorsport 14 mm CP3 Injection Pump, Standard — 2003–2018 Dodge / Ram 5.9L and 6.7L Cummins — CP3-CU-14

S&S Diesel Motorsport 14 mm CP3 high-pressure injection pump, Standard build, for the 2003–2018 Cummins.

Past a certain power level the stock CP3 simply cannot move enough fuel, and no amount of tuning gets around a pump that has run out of displacement.

S&S Diesel Motorsport build a series of 14 mm CP3 high-pressure pumps for exactly that problem — extreme-horsepower applications where the fuel demand is well beyond anything the factory pump was designed for.

This is specialist hardware for a built engine. It belongs in a combination where the injectors, turbo and tuning have all been sized to match.
