my truck has the stock lift pump to my knowledge. the primer lever dosent seem to be working right. with what i have done to it it seems like it should have some more geetyup. could a weak lift pump be the cause. i wanna change to the piston pump but cant find the spacer.

 

call a cummins shop and give them teh part numbers for teh spacer.

 

i tried the numbers that are in the sticky deal about puttin a piston lift pump on a first gen. they couldnt find that number in their computer. guess they changed in

 

thats cummins for ya..... have that pronlem at work a lot
