So I am looking nat cummins diesels but have been avoiding the VP44 because of all of the woe which accompanies it. I want the run straight vegetable oil in it. Does anyone have experience with this? I figured this would be the place to ask guys abou their pumps since you all have em. It would be great if you would just tell me about your experiences and what you think about the pump. Also how much is it to get e new one? Also what should be done to get the most life out of a stock configuration (aftermarket lifter?)? Also were there any changes to the pump between 98.5 and 02 because I have heard the 01-02's were improved?
Thanks in advance
Justin(future proud cummins owner)

 

I believe you'd do better with the '94-'98 12 valve engine with the P7100 inline pump. They're built stronger and will handle abuse better than the VP44 distributor pump.

 

I agree with the above statement but i dont know anything about vegy fuil stuff. You otta post the same thing in the bio fuel forum under the general discussion section. Those guys really know their stuff it seems like.

 

^Completely agree the P-pump is much more accepting of v-oil than the VP.
