The Fleece Performance CP3K is a high-performance modified injection pump engineered to remove the factory fuel flow restrictions found in the 5.9L Cummins platform. If your stock CP3 pump is causing a loss of fuel flow and rail pressure above 3,000 RPM, the CP3K is the definitive solution to keep your engine fueling correctly under heavy load.
By optimizing the internal flow characteristics of the CP3 pump, the CP3K ensures that your injectors receive the fuel volume they need to support aggressive tuning and larger nozzle upgrades. This pump is designed to provide a smoother power curve and improved throttle response, making it the perfect choice for daily drivers and dedicated work trucks alike. Don't let a restrictive stock pump hold your engine back from its true potential. Experience the difference in power and efficiency with the Fleece Performance CP3K, brought to you by GGCRACING.
