S&S Diesel CP3-CU-SS SuperSport CP3 Pump – 5.9L & 6.7L Cummins (2003–2018)

Upgrade your Cummins fuel system with the S&S Diesel Motorsport SuperSport CP3 Pump (CP3-CU-SS). This brand-new, 6.7L-based high-pressure CP3 is engineered for stronger fuel delivery and rock-solid rail pressure above 3,500 RPM—where a stock CP3 starts to fall off.

Built from new OE cores and blueprinted to S&S standards, the SuperSport is the ideal first upgrade for daily drivers, tow rigs, and street trucks in the 500–550 HP range. It delivers improved displacement and efficiency for better performance and reliability whether you’re running stock or modified injectors.

Key Benefits

• Higher output and sustained rail pressure above 3,500 RPM (stock pumps typically fade around 3,000 RPM)
• Excellent drivability and stability for street, towing, and mild performance use
• Brand-new construction (not remanufactured) with no core charge
• Supports both stock and tuned applications
• Proven S&S Diesel Motorsport quality and calibration

Fitment

• 2003–2007 Dodge Ram 2500/3500 5.9L Cummins (common-rail)
• 2007.5–2018 Ram 2500/3500 6.7L Cummins (common-rail)

Important Notes: All S&S Cummins CP3 pumps are built on the 6.7L architecture. Installing on a 2003–2007 5.9L requires minor high-pressure fuel line modification or an adaptation kit (such as the Fleece HP Fuel Line Adaptation Kit FPE-CUMM-CP3-FL-ADPT-KIT).

A quality lift pump (150 GPH or higher recommended) is strongly advised for best results and longevity.

S&S Diesel Motorsport pumps typically carry a 2-year warranty.

The S&S SuperSport CP3 is the smart, reliable step up from a failing or underperforming stock pump—delivering the fueling stability your Cummins needs without the cost or complexity of a full race pump.
