What causes a car to have trouble filling the gas tank?
What causes a car to have trouble filling the gas tank? Trouble filling gas tank, gas pump nozzle clicks off when the car is not full, or spills out of the car. What is causing this? A bad gas cap will cause the light to come on, of so replace the cap. The vent is not working if gas is coming back at you. Replace with new. Why does my gas pump turn off when I fill the tank? The air in the tank has to go somewhere or it will burp back up the fill tube and shut off...
