2007.5-2018 Dodge Ram 6.7L Cummins CP3 Injection Pump (Pickup and Cab & Chassis) | Bosch 0445020146 New
This is a new Bosch CP3 high-pressure common-rail pump, Bosch 0445020146. It is the pump for the 6.7L Cummins in 2007.5 to 2018 Dodge Ram and Ram 2500 and 3500 pickups and Ram 3500, 4500 and 5500 cab and chassis trucks. It replaces earlier Bosch numbers 0445020106, 0445020076 and 0445020047 and matches Cummins 5264247, 4940423, 4947456 and 4944084 and Mopar 68027022AC. It is a new pump, not a rebuild. The Bosch remanufactured version of the same pump is 0986437334.
Common reasons to replace a CP3 are low rail pressure codes, hard starting, loss of power under load, or metal in the fuel filters. Water or dirt in the fuel is the usual root cause, so fix that before the new pump goes on. This pump stops at the 2018 model year. 2021 to 2024 trucks take Bosch 0445020377, and the midrange ISB 6.7 in medium-duty trucks and buses uses different Bosch CP3 numbers.

Replace the fuel filters and check fuel supply to the pump before fitting. If the old pump left metal in the filters, clean the tank, lines and rail and check the injectors, or the debris will damage the new pump. Move the drive gear over from the old pump if the replacement comes without one, follow the service manual for the gear nut torque and any pump timing step, and prime the fuel system before cranking.
