Fleece Performance CP3K Pump – 2003–2007 Dodge RAM 5.9L Cummins | Part #FPE-CUMM-CP3K-5.9
Upgrade your fuel system and maintain full power across the entire RPM range with the CP3K Pump from Fleece Performance Engineering. Designed specifically for 2003–2007 trucks equipped with the 5.9L Cummins, this upgraded pump replaces the factory unit with a modified 6.7L CP3 that eliminates the common fuel flow restriction that occurs around 3,000 RPM.
Factory CP3 pumps often struggle to maintain adequate fuel rail pressure at higher RPMs, which can lead to reduced horsepower and performance when you need it most. The CP3K pump upgrade allows your fuel system to maintain proper rail pressure throughout the entire RPM range, improving overall engine performance and reliability.
Built around a brand new Bosch CP3 pump, this kit provides a durable, high-quality solution for diesel owners looking to improve fuel delivery without the complexity of larger dual-pump systems.
