After that there is all sorts of stuff you can hook up. I make do with just the above, my EGR valves are all non operable, the tank is vented through the gas cap, the TAC was lost years ago etc.
Don't forget the PCV system that sucks out harm full crankcase vapor. Unless you want to run a road draft tube but the crankcase needs to be vented.

If it's stock, it's not vented, Venting was done through the evap container on the fire wall.

If the o-rings on the cap are cracked and rotted. then it's 'vented'

Can I buy a vented cap so I don't have to run the canister?

Good question. I don't know but I found out most Locking gas caps seat so poorly they vent all the time. E-check cant even get them to fit on their tester so I pass all the time...
