74 charger charcoal canister

[charger318]

I was wondering where the 3 lines go from canister I see two larger rubber hoses that go to hard lines that run under the car and one smaller hose just hanging loose? Anyone know where suppose to be? Previous owner put a Holley 750 vac Carb on it that matters

I may be mistaken and other will chime in too

The three ports on the charcoal container are; gas tank vapor port (smallest), the carb fuel bowl vent and the purge port. if the carb does not have the fuel bowl ported vent just cap that port on the canister. Now the purge port i think (not certain as my brains not working right today) goes to the intake manifold vacuum.

I don't have a line from the fuel tank to my canister. Where does the gas tank vapor port end before the rubber tube comes to the canister so I can replace the rubber tube
