I just installed a new Carter (I know) lift pump on my 93 6.5 Turbo Diesel. Before I switched I installed a pressure gauge between the fuel filter and the IP, which read anywhere from 5 to 6 psi at idle.
Now that I have my new LP installed, the psi is exactly the same. From what I understand should it be closer to 10 to 12 psi at idle?
Its a Mechanical IP but like I said the gauge is before the IP. Is this psi ok or should I be looking elsewhere for a problem?
It also has a new fuel filter installed.
It starts great, runs at idle forever, then dies after driving a few minutes. Typical yes, but trying to figure this fuel pressure out before anything else. Thanx
After letting it idle at 6 psi, I ran it up and down the driveway a few times and actually got a vacuum, what?
There a no noticable fuel leaks, defiantely lost. Had to walk away for the day
