Thumbnail Filmstrip of 5.9|6.7 Cummins New CP3 Injection Pump S&S Diesel CP3-CU-14 Images
The S&S Diesel CP3-CU-14 14mm high-pressure fuel pump represents a significant leap in injection technology for the 2003–2024 5.9L and 6.7L Cummins engines. While standard pumps often struggle to maintain rail pressure as engine speeds climb, S&S Diesel has re-engineered this unit to prioritize high-speed efficiency. By modifying the internal geometry beyond a simple displacement increase, S&S ensures that fuel delivery remains consistent well past the peak RPM limits of most conventional diesel engines. This commitment to over-engineering transforms a critical engine component into a reliable powerhouse capable of supporting both extreme competition demands and high-performance daily applications.
- High-Volume Displacement: Specifically engineered to handle a massive 1,850 mm3/rev, providing the volume necessary for high-horsepower builds.
- High-RPM Calibration: Internally modified to maintain fueling efficiency at engine speeds that cause standard pumps to lose pressure.
- Hybrid Construction: Utilizes a strategic combination of high-grade aluminum and steel to balance weight reduction with structural integrity.
- Proven Durability: Built to withstand the extreme mechanical stresses and thermal loads inherent in modern high-pressure common rail (HPCR) systems.
- Precision Engineering: Crafted from heavy-duty materials to ensure the pump maintains internal tolerances even under maximum load.
Choosing the 14mm CP3 is an investment in the longevity and ceiling of your Cummins powerplant. Because S&S Diesel treats "competition-grade" as their baseline standard, users benefit from a pump that is never operating at its absolute limit during normal use, which significantly reduces the risk of cavitation or mechanical failure. Whether you are building a dedicated sled puller or a high-output street truck, the data-driven design of the CP3-CU-14 provides the peace of mind that your fuel system can outperform your expectations.
Note: All S&S CP3 Pumps for Dodge Trucks are built from a 6.7 based pump. If you are installing these pumps on a 5.9 truck, some modification will need to be made to the stock fuel lines
