This all varies somewhat, depending on the style of canister you have. If it's the stock '85 style, then
it will have a sort of "F" connector on one port, and a mushroom cap on the other. The fuel bowl vent
hose will connect to the larger diameter nipple on the F connector, and everything else connects to
the smaller nipple, using tees as required. For your setup, that will pretty much be just the tank vent
line, and the canister port on the purge valve. Pretty simple.
Again, this post shows what goes where on the purge valve -

Where it says ported vacuum, that will be EGR vacuum in your case. (Ported for engines that don't
have an EGR vacuum source.)
The purge system does not pull a vacuum on the tank, because that mushroom cap on the other port
on the canister lets air in, to purge the vapors.
You are correct that you do not want to connect up the bowl vent until you have a vent solenoid for it.
The vent solenoid closes when the ignition is on, so the fuel bowl pressure is referenced to the inside
of the air cleaner. You will also want to cap the unused larger nipple on the F connector.
