The PO put in an electric fuel pump after the stock one crapped out. Someone took the spoon off the stock pump and left it on there to keep oil in the engine. My question is do I need a fuel pressure regulator? Also there is no fuel return line to the tank, which I think there should be. The engine also diesels, and Im thinking that this may have something to do with the whole setup as well instead of the timing. When I start it, sometimes black smoke comes out of the tailpipe and it stinks of unburnt gas from the tailpipe (This is my first rig w/o a catalytic converter as well, so I figured this was the case for the gas smell...now I may be wrong.). I had thought it may be the head leaking oil, but after pulling it, it seems fine. The PO would not be mistaken for a brain surgeon nor a rocket scientist. This question came to me after reading the other post about the cruiser with the black smoke and high idle. Your thoughts?
