Something is incredibly wrong. Gasoline left out in a 5 gallon bucket won't evaporate in two months. Basically your problem can't be happening unless its leaking so badly that there are massive puddles on the floor.

It sounds like you need a new evap purge valve. It should be closed in most situations (like when the car is off) which keeps gas from free flowing out of the tank ... and at this point, definitely a new charcoal canister. If its been exposed to that much liquid fuel its not very effective anymore.
