Welcome aboard thirdgen.org.
You either keep the in-tank electric pump operating and use a return-style regulator such as the Mallory 4309, or you remove the in-tank electric and replace it with a carb'd 3rd gen pick-up. If you look on the Carburetor forum, there's a sticky at the top of the page that describes how to convert an EFI pick-up to a mechanical fuel pump pick-up.
