Charcoal canister line routing.

I have a 73 scamp 318. Previous owner put on a Holley 600 carb and just left the charcoal canister lines off. All that is Hooke up is the line coming from the tank. Where would I hook up my line from the canister since the Holley carb doesn’t have the bowl vent? I imagine I only need to hook up one line to car somewhere and block off third on canister.
