S&S Diesel Motorsports CP3-CU-12 New 12mm Stroker CP3 High-Pressure Fuel Pump for Cummins

The S&S Diesel Motorsports CP3-CU-12 is a brand-new 12mm stroker high-pressure CP3 injection pump built on the 6.7L Cummins platform. With a 1,590 mm³/rev displacement, this pump delivers a significant increase in fuel volume over the factory unit, making it a top choice for performance and high-horsepower common rail diesel builds.

Key Features:

• 12mm stroker design — 1,590 mm³/rev displacement for increased fuel delivery over stock
• 6.7L-based architecture — new-build pump, not a reman or modified core
• Rated for applications up to 1,000 HP on common rail 5.9L and 6.7L Cummins platforms
• Brand new unit — not remanufactured, no core charge
• Compatible with S&S SP3000 supply pump for full fuel delivery system builds
• 1-Year warranty included

Installation Notes:

• All S&S CP3 pumps are 6.7L-based; when installing on a 5.9L (2003–2007), high-pressure line/fittings must be adapted to 6.7L style
• A lift pump rated at 150 GPH or higher is recommended for optimal performance
• Does not include fuel lines, fittings, controller, or lift pump

S&S Diesel Motorsports is one of the most respected names in common rail diesel fuel system performance. The CP3-CU-12 is ideal for truck pullers, drag racers, and high-output street/strip builds demanding reliable, high-volume fuel delivery.
