HELP!
Alright, since my last post I removed and re installed the motor and tranny to replace a clutch throwout bearing. I installed a new fuel filter, she starts up on the first crank even on cold days without gp's. However , after my first drive about 5-7min in to the drive the symptoms re appeared (loss of power and stalling).
So I bought the 911 diesel supplement to de-ice fuel and poured it in to my tank to rule out an iced fuel/ or pump pickup. Went out for a drive and the same symptoms happened about the same time 5-10min into the drive.Now ,sometimes if I let the motor bog down it will run like crap for a minute then revive itself with a few blips of the trottle. A few other things I noticed is that when the symptoms are occuring ,the motor will stay alive if I keep the revs up really high. Secondly, my truck use to boost easily to 20-25psi and now it struggles to reach 5-8psi.
Today I went to get some clear fuel line to see if there was air in the system. After the hose install , you can see in the first and second video that there is plenty of air in the lines ( more on the supply side than the return) . I tried pressing and jiggling the fuel filter T and there was no change. Could being low on fuel (1 bar over Empty ) affect this somehow? Its been pretty cold here (-15c to -30) lately i'm sure thats not helping.
