Thread: 1971 cadillac fuel pump

Tweet

i do not know which line goes where on my 71 mechanical fuel pump. it has 3 lines. my handy dandy pos haynes model does not say. thanks guys for the help.

Barb the fitting that is threaded goes to the inlet of the carb, the larger of the 2 nipples is for the supply from the tank and the smaller is for a return line to the tank (if the Monte doesn't have a retun to the tank this can be plugged).

no the monte dos not and that is what i was planning to do thanks mike.
