Hi I'm a fresh one on here ,i have a 1988 f350 7.3 na , heres what happens i pulled this truck outa the weeds an started using it as my daily driver, been driving it for couple months now ,driving no more than 40 minute at a time usually alot less been doin good. I had a lift pump go out an i put a electric mr gasket on there an it ran good for a while but i just went aways from home for work bout three hours ,ans it dies twice on me ,leaving me on the side of the road for 30 mins both times, first time i bled all the air to the filter an then cracked injector line (1&5) an got some air out an it crunk up while the lineslines we're cracked an rain good for 30 miles an started sounded like weak and missing just a little bit drove for a while an died again this time it had no air an no fuel to injectors but I had tried jump in the fss also it wouldn't crank on ether or wd40 an had to wait on someone to come jump me off! An it alsudden fired up !Got to where I was going an now I checkedthe fuel pressure an it was low like 1-1/2 psian none wen u hit the gas. So I put a new mechanical one on and i have great pressure an volume but there sounds like a slight miss or hesitation. Any idea from y'all ? Thanks in advance
