Upgrade fuel delivery on your 2001-2016 Duramax with the Fleece Performance CP3K Injection Pump. Part FPE-DMAX-CP3K is a brand-new modified Bosch LBZ CP3 designed to eliminate the factory fuel-flow restriction that begins near 3,000 RPM. By helping maintain desired fuel rail pressure throughout the RPM range, the CP3K supports consistent fueling when stock CP3 output begins to fall off. No core charge or core return is required.
