Before the Barra. 1980s Ford EFI, ZL Fairl;ane. The unplanned part2! Diagnosing.... Again!!

After a couple weeks of driving nicely, the ZL Fairlane suffers the same problem as before. Digging deeper into the work previously done by the owner and finding some issues that have reappeared, we work out a plan of repair.

Looks like that fuel pump is NOT the correct one. 4.1 EFI engine run a bigger pump from memory. I replaced my fuel pump in my 4.1 EFI a few years ago and that one you have there definitely looks incorrect for that car. Bosch is original part Ford used in the day! Please check part number...
