Yes, my 70 440 had one. A return helped my 67 a lot, rear mount electric pump, carb spacer, and Wix filter with return
OP what kind of car? If you have a 70/ later with the evap 1/4" line up front THAT IS THE tank vent and you must leave it open. Either provide an alternative vent, or leave it be and string a new line for return. ON my 67 I drained the tank and flooded it with CO2, punched (not drilled) a hole in the tank near the sender and silver brazed it in. You can also get a sender with a second line fitting.
The Wix filter must have the 1/4" return nipple "at top" either vertical or horizontal Wix no. 33040 or 33041, 5/16 or 3/8 lines. There's also a 33054 with the return nipple at right angles
