In principle, all the tank needs is a vacuum source to suck fuel vapors out and a fresh air source that can supply air at least at the same rate as the vacuum source purges the tank. Also, the vacuum line set up in such a way as to disallow liquid fuel from being sucked in (which, by experience, my setup seems to achieve).
In which case, on the tank itself you only really need one line in and one line out (which is what I have).
I'm not familiar with all the hook ups on a 96 formula canister, but I can't imagine it's too much different than my '90 TPI unit.
My canister has only two hose connections:
1.) Main vent line to the tank
2.) Constant vacuum source. The vacuum line actually hooks up to the electronic solenoid mounted on top of the canister. The ECM controls the solenoid open/close as to when to start/stop purging the tank.
