Fleece Performance CP3K Fuel Pump

2007–2014 Dodge Ram 2500 / Ram 3500 6.7L Cummins

FPE-CUMM-CP3K-6.7

Overview:

The Fleece Performance CP3K Fuel Pump is a precision-engineered upgrade designed specifically for Dodge Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins engine from 2007 to 2014. This modified CP3 pump addresses the common factory fuel flow restriction that occurs above 3,000 RPM, which can limit fuel delivery and reduce engine performance under load. By eliminating this restriction, the CP3K ensures consistent fuel rail pressure throughout the entire RPM range, enhancing throttle response and overall power delivery.

Ideal for diesel enthusiasts seeking a cost-effective and reliable solution to improve fueling on stock or mildly modified trucks, the CP3K is also an excellent choice for dual pump setups where maintaining optimal fuel flow is critical. Each pump undergoes rigorous testing on Fleece Performance’s in-house engine simulator and pump test stand to guarantee durability and real-world performance.
