What is the proper psi, and gph December 20, 2018 at 3:47 pm #14357 jensenracing77Participant I am for sure not an expert on electric fuel pumps but the stock 215 2 bbl and 4 bbl engine pump was 5-6 PSI.

If your car has a return line back to the tank then maybe a 3/8 line would be best.

I have no idea if they replaced the lines. what recommendations are for this?

If the rubber hoses are really old you will likely need to replace them. Author Posts Viewing 5 posts - 1 through 5 (of 5 total) You must be logged in to reply to this topic.
