interesting, my 70 Fury has that tank inside the main fuel tank and has the separator in the trunk (just a tall vent with the 4 lines going into it).

Are you trying to restore it correctly or just have it run? You don't need it to run, you can just plug the extra ports for the separator in the main tank and run a vented cap like the pre-emission cars do, and not hook up the hose to the breather and carb.
