I have a 93 4cyl hatch that I will be doing an ls carb'd swap on. Whats the easiest way to get it up and going? I have seen the adapters to change the push connect fittings to AN. Could I do this and run AN line up to a regulator and use the stock pump? A walbro 255? Or do I need to do something different? Also what about a return?

I don't know the specifics of the mustang fuel system, but I ran a walbro 255 for a fox mustang in my swapped rx7 for years. This was with the stock 5/16 lines (feed and return) and had no problem getting the pressure down to 6 psi using a cheap Mr Gasket return style regulator. I want to say you'll be fine. There is no problem running an efi pump on a carbureted setup. It's easier on the pump, actually.

As above.

With a suitable regulator and return line the efi pump will work just fine
