High-Pressure Injection Pump Modified CP3K

Eliminate performance bottlenecks with the Fleece Performance CP3K (FPE-CUMM-CP3K-6.7), a drop-in replacement CP3 designed specifically for 2007.5–2018 Dodge RAM 2500/3500 trucks with the 6.7L Cummins engine. If you're still running a stock CP3, you're likely experiencing fuel flow restrictions beyond 3,000 RPM, leading to a loss of rail pressure and horsepower right when your engine needs it most. This cost-effective and reliable solution ensures your truck maintains desired fuel pressure across the full RPM range, improving power delivery and efficiency under load, during acceleration, or when towing. Capable of supporting up to 600 rwhp, it’s a solid upgrade for high-performance street builds, weekend warriors, and mild race setups. Because it’s built from 100% new components, there’s no core charge, no risk of internal wear, and no remanufacturing compromises. It integrates seamlessly into your truck's existing fuel system, using OEM electronics and fittings, making installation straightforward and dependable. Whether used as a standalone upgrade or as part of a dual CP3 setup, the CP3K delivers where stock pumps fall short.
