Which one is better? (long)

1971 dart. putting a 96 5.9 magnum in it. Going to use the factory EFI, wiring, fuse box and as much as possible. It will have a 904 in it. I need a new gas tank. Mine has the 1 nipple above the sending unit for a return (vent). Would the tank with the 4 nipples be a better choice? I could then have a return and vent for gas tank. Thought about piggybacking the tank vent to the return line but it might be a smell/leak hazard.
