Most of you reading my question will think that I have gone start raving mad. Too late, I already went mad years ago.

The following is NOT something I intend to do,(yet), but am curious. For my common rail Cummins, would it be possible to remove the CP3 and install an older model pump that would run totally without electrics or electronics? To do this, could I use the existing case that the CP3 mounts on, or would I have to change some gears and the case?
It it were possible, which would be the best pump?
Naturally the injectors would have to be changed too, so which injectors? Would it be possible to just drop in injectors, or would I also have to change the head?

 

You'd have to go back to the '98.5-'02 head, injectors, and timing case and swap on a P7100 pump off a 12 valve.

Lots of good info...they may have some info for what you are trying to do.

Thanks for the replies so far. Good link Tony, thanks.

 

hey i'm thinking of doing the same thing to my 07 5.9 after i get it honed out was going to see what it takes . their is some info here about doing a p pump conversion here but its not to helpful. i know it takes timing gear case and gear replacement. i'm gonna go with a 24v head and injectors. also gotta change the go peddle set up plus not sure what else as far as electronics
