Sounds like you have a cracked vent hose INSIDE the car.
The fuel vapor recovery tank is located on the right hand side to the front of the fuel filler neck. The hoses from the tank connect to the filler neck inside the car as well as being routed to the tank via the back panel. Those are the ones that get dry and crack.
The only way to fix this right, is to change the vent hoses.
