The Fleece Performance CP3K is a modified 5.9L Cummins CP3 pump designed to address factory fuel flow restrictions that occur at 3,000 RPM. This upgrade effectively eliminates the loss of fuel flow and rail pressure beyond this point, ensuring consistent fuel delivery and horsepower across the entire RPM range. Constructed as a cost-effective solution, the CP3K enhances performance by maintaining optimal fuel rail pressure during high-demand situations. It is specifically engineered to improve fuel delivery without compromising durability, making it a reliable upgrade for high-performance applications.
This product is intended for 2003-2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins engine. It should be used with stock CP3 pumps and is not suitable for belt drive or dual pump setups. The CP3K serves as a direct replacement and upgrade for stock units, providing improved fuel flow at higher RPMs. It is ideal for performance enthusiasts seeking increased horsepower and consistent fuel delivery during towing, off-road, or high-performance driving scenarios. Installation is straightforward for those familiar with diesel fuel systems, and the kit includes the modified pump ready for installation.
