The Fleece Performance CP3K for 2007.5–2012 6.7L Cummins is a modified CP3 pump that removes the factory fuel flow restriction beginning at 3,000 RPM, allowing consistent rail pressure across the RPM band. It’s a solid option where full fuel flow beyond 3,000 RPM is needed but the extra volume of a PowerFlo 750 is not required, including suitability for certain dual-pump configurations.
