difficult filling my gas tankIs there a vapor vent tube coming off the gas tank?

What is your question?

When I go to fill my car with gas, the fuel nozzle keeps cutting off the flow of gas. ( Like it's tank is full) I saw a service bulletin from another make of car,suggesting the problem is with a vapor tube that goes from the gas tank to an evaporative emission canister. B4 I lower the gas tank, is this reasonable thing to fix my problem?
