    I want to know how to determine the proper size electric fuel pump. What is the proper psi, and gph



    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.



    In my opinion, Anything with a pressure around 5-7 lbs that has a 5/16 to 3/8 line is going to supply enough for a carburetor. If your car has a return line back to the tank then maybe a 3/8 line would be best.



    The people that had this before me stuck an elec. fuel pump in it. I have no idea if they replaced the lines. what recommendations are for this?



    If your lines are not plugged up or leaking then you should be fine. If the rubber hoses are really old you will likely need to replace them.
