C320 Purge Valve Location?
Where is the purge valve located on the C320? Just curious, I've read that they need maintenance/cleaning? Is that true? I don't see why if the valve just returns unused gas to the tank. Or my understanding of the valve is incorrect.

Incorrect.
Purge valve allows accumulating gas fumes that are filtered through the canister to be combined with intake mixture to be burned instead of entering the atmosphere.
Gas return to tank is different system where pressurized gas from the pump satisfies engine load/pressure and the remainder returns to the tank to keep a constant loop/fuel pressure...
