I have a problem. I blew a hole in the back part of my pump. And i have a guy that will sell me one off of an 8.3 cummins. He sent me pics and they look exactly the same on everything and i figured the only difference might be a bigger cam and plungers. But i don't want to spend money on it since i have very little and then it not fit. It's also a p-pump and everything. I could really use ya'lls help on this. thanks.
and they have the same measurements for the bolt holes. 4 in at the top and 4 3/4 at the bottom i think they would work.

 

it is alot bigger pump you could use it it will just be alot of fuel

 

mk i was looking to add more fuel to it neways i just didnt want to buy it without knowing forsure it would work. i know it'll bolt up and all and if its putting to much fuel to it i could always slide the fuel plate a lil more shut in side of it.
