so i pinched the line a little bit and the fuel pressure was still around 10psi at idol and then went up to maybe 25 when i pushed to 3500rpm, i then pinched it all the way and when i got on it, it went straight to 0??? maybe just somthing i did wrong, i replace the lift pump around 5yrs ago with a new one from Pensacola Diesel, the outlet line was a bit differnt hook up so i had to rig up so home depote brass fittings, hose clamps, and fuel hose, maybe thats my problem???

ah i see, whats your guys opinions on the 4 hole 90hp injectors? i know of another set i could get and swap them out but they are really big supposebly, they came off a truck done by A to Z Diesel here locally in mesa, the tech that pulled them said they were too much but im wondering if they were too much because he was also running a race p pump and completely built motor and a different cam. he has like 18k into the motor build to give you an idea of whats done to it

so i was online looking at performace parts for the p-pumps and found new delivery valve holders that are much bigger than the stock ones, they are the things that you need a special socket to remove and the new ones are six sided not splinded, my question is-i thought they were shimed and fit to a paticular barrel??? or are the spring things inside are whats shimed to each barrel?
