I'm Awesome
The vent is in the center, right next to it is the vent from the tank and the outer fitting to itself is the purge vacuum signal. It was just a 3/16" nylon tube to ported vacuum from GM. I changed both the rubber hoses from the metal line to the tank and the canister to the metal line and blew air through the metal tube allowing the tank to vent as it should.
