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.
This is going to depend on a number of things.
Do you plan on running the charcoal cannister from the '96?
Does the '96 use a fuel return line or is it a returnless system? (Mopar used both over the course of the Magnum's life- I don't remember offhand which was being used in '96)
Does your Dart currently have a tank vent in the filler tube?
Are you planning on running a stock tank with the Holley or Spectra conversion pump/sending unit module, run an external pump, or get a complete tank/pump replacement from a vendor like Tanks Inc.?
