Would a fuel pump of a 1973 350cui Pontiac engine fit in a 1970 350 cui Pontiac engine? Where is the return line conected to? There are only two lines from the fuel pump, one from the tank and one to the carburetor.
Sounds like you kinda answered your own question. If the pump you want to put on does not have a 3rd (return) outlet and your car has a return fuel line, then you need to get another fuel pump with 3 outlets.
