CP3 Pump

Deliver rock-solid high-pressure fuel volume, eliminate factory pump failures, and support heavy-horsepower tuning on your 2007.5–2009 3rd Gen 6.7L Cummins with a high-performance CP3 fuel pump upgrade. Factory emissions-era fuel systems can suffer from delivery limitations under load, making a robust CP3 pump essential for maintaining steady rail pressure and protecting your expensive injectors. Upgrading to a heavy-duty replacement CP3 pump or conversion kit ensures consistent fuel volume, prevents pressure drops during heavy towing or wide-open throttle, and delivers bulletproof reliability under extreme-duty use. Shop top-tier CP3 pumps engineered for exact OE fitment and severe-duty performance.
