Gas will not go into the tank without the pump cutting off. I am using the same stations I have used for years and have tried older stations as well. Same problem. Initially, about a gallon will go in sometimes more than the pump shuts off. I try again, a little more gas, pump shuts off. It takes me 1/2hr to get a half tank. I’ve tried filling the gas at a slower rate to avoid splashing the side nothing works.(also get spillage) Any ideas? Currently have 120K miles on van. I travel from Maryland to Boston quite frequently, so I need this fixed quickly. Someone mentioned the charcoal canister or a small tube that goes into the canister may be clogged. Any thoughts would be appreciated. Trying to be knowledgeable before taking to mechanic.

I hesitate to say this, but pulling back the rubber collar on the gas pump so as to leave an air space between the rubber collar and the car's filler tube usually solves the problem. But you will be venting gasoline-laden fumes into the atmosphere.
