For the last few weeks, ive been unable to fill up my gas tank without a battle at the pumps. The pumps have a sensitive pressure cutoff, and I can only put gas in for about a few seconds. So it takes about 15 minutes to fill up my car, and some gas ends up spilling on my car which is annoying. I took out to check a one way valve on the filler neck, and its ok. What could be the problem, the solution, and anyone else who is experiencing this problem to help. Quick respones is appreciated thanks, rather not take it in to the dealer.
