4 where do gas vent tubes in a 1971 dodge dart connect?

In a 1971 Dodge Dart, gas vent tubes typically connect to the fuel tank and the charcoal canister as part of the evaporative emission control system. The vent tube allows fuel vapors to escape from the tank and directs them to the charcoal canister, where they are stored until they can be burned in the engine. This setup helps prevent fuel vapor release into the atmosphere. Additionally, the vent tube may connect to the filler neck to allow air to escape as fuel is added.
