S&S Diesel Motorsport CP3-CU-10 – 10mm CP3 High-Pressure Fuel Pump For 2003–2018 5.9L & 6.7L Cummins

The S&S Diesel Motorsport CP3-CU-10 is a brand-new 10mm stroker CP3 injection pump built on the latest-generation Bosch CP3NH base. It delivers 1,325 mm³/rev of displacement (approximately 22% more than stock) and a peak output of 318 L/hr at 5,000 RPM, providing the extra fuel volume needed for moderate-to-serious performance builds while maintaining excellent drivability and rail-pressure stability.

Key Features

• Brand-new Bosch CP3NH-based pump (not remanufactured)
• 10mm stroke / 1,325 mm³ per revolution
• Peak flow of 318 L/hr at 5,000 RPM
• Direct drop-in for 6.7L applications — no calibration required
• Fully tested with included data sheet
• Supports applications up to approximately 750–800 hp with proper supporting modifications
• No core charge

Fitment

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

Important Note: All S&S Cummins CP3 pumps are built on a 6.7L-based housing. When installing on a 5.9L truck, the stock fuel supply lines require modification due to the different inlet port location. A high-flow lift pump (150+ GPH recommended) is strongly advised for maximum performance and longevity.

Ideal for trucks running upgraded injectors, mild-to-moderate turbo upgrades, or heavy towing with increased fuel demand. The CP3-CU-10 offers a reliable step up from stock without the complexity of dual-pump systems.
