The Fleece CP3K is the ultimate fuel system upgrade for serious 6.7L Cummins builds. This conversion kit replaces the factory CP4 injection pump with a proven CP3-based system — eliminating the catastrophic failure risk associated with the OEM CP4 while delivering the high-pressure fuel volume needed to support big horsepower. Whether you're building a competition truck or protecting a daily driver, the CP3K is the definitive solution.
