Hello, has anyone had any experience with this pump?

Amazon.com

DRPO2 for 5.9 cummins

Short of any experience with this exact model, do the numbers at least look good for the 4bd1-t?

What injection pump do you have? If it's a Bosch A inline pump it may need a bit more pressure than 23 PSI but that may be workable. Not sure about the A pump but a P pump has the same lift pump on Cummins engines. The basic stock model is supposed to be 17-23 PSI at idle and not below 25 PSI under load. If your 4bd1t has a different pump you need to know its requirement.

The drp-02 doesn't quite create enough pressure for the A-size injection pump. I believe spec is around 1.5 bar in the galley, or 21-22 PSI. The drp-02 puts out maybe 15 psi. If you want to run electric I would step up to the adjustable series of FASS, like the FASD10140G for a 12 valve Cummins. It's overkill for sure, but you have plenty of room for adjustment to meet spec.

Ok, so i confirmed its the original P-Pump. I also have a mechanical lift pump on the block.

Is the pump you noted here adjustable? I wouldn't mind overkill like you say as long as i can dumb it down as needed.

I just found where it says it is indeed adjustable. That would be great to tune it to the exact needs of the engine.
