BD Diesel OEM Bypass Lift Pump | 2003-2004 5.9L Dodge Cummins

Pricing: $365.00

Free Shipping


The BD Diesel OEM Bypass Lift Pump (part #1050227) is a replacement pump for the weak factory lift pump that is a common failure item on the 2002-2003 5.9L Dodge Cummins. The OEM Bypass pump installs by removing your factory lift pump from the engine and relocating it onto the frame, away from all the harsh vibrations of the mighty Cummins engine. This pump is best served as a stock replacement for stock to modified trucks around 50-100hp increase.

This pump is for use on stock trucks and is not intended to keep up with aftermarket tuning or injectors.


  • Bypasses OEM lift pump
  • For stock & lightly modified


  • 12-Months
  • 12,000 miles

Note: This is the pump you should go with if your stock pump has gone bad. It is designed to bypass/eliminate the use of the stock pump on the engine. The way this pump works is it mounts on the frame rail w/ the supplied hardware and wiring harness that plugs directly into your factory harness. This kit mounts on the frame because it's easier for the pump to push fuel rather than pull it from the tank and the vibrations from the motor shorten the life of the pump when it's mounted on the engine.
