The BD-Power 1050227 OEM Bypass Lift Pump for your 2003-2004 Dodge 5.9L Cummins is a replacement pump for the weak factory lift pump that is a common failure item on Dodge Ram Pickups. The OEM Bypass pump installs by removing your factory lift pump from the fuel filter housing 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.


  • For Stock & Lightly Modified
  • Bypasses OEM Lift Pump


This is the pump you should go with if your stock pump has went bad. It is designed to bypass/eliminate the use of the stock pump on the motor. 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.  If your stock pump is still good and your just looking for a little added security you should look into the auxiliary pump.

Should have replaced the stock pump a loooong time ago

Used this pump as a replacement for the stock pump that fails on everybody. As soon as it's installed, you can feel a strong boost in power, and at least for me, has been working like a dream for the past 5 years.

The hardest part of the process is removing the OEM pump. Three of the four allen head bolts are easy to remove. The lower bolt closest to the engine was a bugger to remove. When you install the billet adapter to the fuel filter housing, stick you little finger in the hole and remove the old o-ring. The install took about three hours. I can't believe the difference, the throttle response is much smoother and it even shifts better. The OEM is a cheezy plastic pump. This BD pump is stout and delivers the fuel promised. If you have access to a lift, it will be much easier to mount the pump on the frame under the drivers side standing up. Use a high speed cut off tool to cut through the stainless fuel line.
