I have a 1985 745 that is cutting off after about 5 minutes of driving. If I wait another few minutes it will restart and run another few minutes before cutting off again. We have traced it down to fuel pressure loss. Does anyone know any details about the fuel pump or pumps and the location and part number of the pump relay. Any other ideas.
Thanks,

I doubt its the in-tank pump, as mine was dead for a long time -- really with no difference. Plus it only supplies like 10 psi or something....my guess is the in tank pump is there for the longgevity of the main pump -- which is more likely where your problem lies....also Regulator?? Good luck!
