Push Power To The Limit Without Compromise

If you’re building a Cummins that won’t settle for stock performance, the Fleece Modified CP3K pump is a no-brainer upgrade. This pump is designed specifically to keep up when things get fast and furious above 3000 RPM, where a factory pump just can’t deliver. The CP3K ensures your fuel system doesn’t become a weak link when you’re pushing horsepower on the street or strip. It delivers consistent fuel flow when you need it most, helping you maintain rail pressure and keep power delivery strong through the full RPM range. You’ll feel the difference in responsiveness and reliability, especially in high-performance applications where every drop of fuel counts. This is the kind of upgrade that keeps your build running strong under pressure and performing like it should. If you’ve already added tuning, injectors, or a bigger turbo, this pump ties it all together with the fuel supply to match.

Engineered To Perform Beyond Factory Limits

The Fleece Performance CP3K is a modified CP3 injection pump designed for the 2003-2007 5.9L Cummins, eliminating the common fuel delivery limitations seen in stock configurations. At engine speeds above 3000 RPM, factory pumps struggle to maintain rail pressure, leading to decreased horsepower and inconsistent performance. The CP3K solves that by increasing fuel volume output without the need for dual pump systems or belt-driven setups. It's a drop-in upgrade that works within the existing fuel system while enhancing efficiency across the entire RPM band. Built with durability and reliability in mind, this pump supports advanced tuning strategies and larger injectors without compromise. Fleece’s modification process ensures smooth operation and longevity while boosting your system’s capacity for high-demand driving. This pump is best suited for single CP3 applications and should not be used in a belt-drive dual pump configuration.
