M1008 injection pump question

[cbr600rx7]

I think my injection pump is on its way out. My biggest question is what is the difference from the 6.5 (DB2831-5149 and 6.5 de-tuned (DB2831-5209) injection pumps. I also have a 6.2 pump off a K10 civilian truck sitting in the garage but im not sure how interchangeable civilian stuff is with the cucv.

I don't know the first question, but a civi ip will fit on a cucv

light white smoke and didn't want to stay running. there is fuel going to the pump but i am not getting any out the lines.

CUCV IP's are 12v, the HMMWV ones are 24v and you would have to swap the top cover/solenoid for a 12v one to make it work. A rebuilt civvy pump is cheaper and easier unless you have a real cheap source for HMMWV pumps.

The pump from the K10 should be a straight bolt in.

I have a DB2 831 5485 sitting in the garage right now that should be good. Its a 24 volt but my solenoid is still clicking on my other pump so i am thinking about giving it a try.

I would first start by changing the fuel shut off solenoid on the pump and rule that out.. when they get old sometimes they will only partially energize and not open all the way. if you look in TM 9-2815-237-34 it will give you all the setting for these pumps THEY ARE DIFFERENT!!! i know that they will work to get you by but may cost you in the long run... would hate for you to burn holes in pistons.... the fuel delivery rates are different and the cam movments are different. A CIVI 6.2 pump will work just fine here
