CP3 Pumps

Deliver relentless high-pressure fuel volume, eliminate pressure drops, and restore peak performance to your 2003–2007 3rd Gen 5.9L Cummins with a heavy-duty CP3 injection pump. Factory injection pumps wear out over time, leading to hard starts, low rail pressure codes, and power loss under heavy loads or towing. Upgrading or replacing your CP3 pump ensures precise fuel metering, rock-solid rail pressure stability, and the dependable high-pressure output your common rail engine demands. Shop top-tier stock, modified, and dual CP3 fuel pumps engineered for exact OE fitment and extreme-duty durability.
