I have a 70 A-body and would like to find a diagram of a fuel system. I need to have a feed line and a return lind. Car has a 502 crate motor w/850 double pumper, and has an AC Delco electric pump. For some reason the pump keeps burning up and has problems with vapor lock. I'd like to be able to find a list of parts that I need to complete an installation of a fuel system w/regulator. Thanks in advance

Welcome to the site.

I posted this for another CF(Chevelle fan) but I will have no problem going over this again. 1. what are the size of the fuel outlets on your tank?The outlet needs to be at least 3\8 Id..2 Is the strainer sock still on the end of the sender unit? Remove that and install a large fuel inline fuel filter past the fuel pump. The strainer socks are not designed for a constant suction pressure that an electric pump will provide.I do not have any parts lists or diagrams but I am in the process of instaling a fuel injection setup on my 72 and I gave up on trying to get the stock style sender unit lines to work in properly feeding the fuel to even my little 383.I had a sump installed on the bottom of a new tank with AN8 fittings and I am going to use the stock feeder outlet for the return....Sorry fer the long winded post but I hope it helps some.
