HI ALL

I got a problem with my gas tank. When Im filling, it stops like it was done. It doesnt even take a gallon before it stops. It never did it before. I tried 5 gas stations with 3 different nozzles. I know its not the gas stations or the nozzles. Ive tried jiggling it and everything else I can do. Nothing works.[B)]It's kicking my butt[B)] It's been a vary frustrating pumping gas and slightly embarrassing. Its takes 10 more min. to put 10 gallons in then it used to. I have been to busy to take it in. Could there be something at the end of the pipe going to the gas tank or could it be in the tank? Has anyone had this problem before? [:I][:I][:I]HELP!!![:0]
