I am having a problem when I attempt to fill my car’s gas tank up. Unless I barely squeeze the gas nozzle the gas flow will shut off as if my tank is full, which I know it’s not. Eventually I can get the tank filled, but it takes quite a while. It’s as if the air pressure in the gas tank is not finding a way out as I put gasoline into the tank. Could a vent be blocked? If so, where would it be located?
There’s a vent valve in the EVAP system that’s suppose to allow the gas tank to vent when refueling.
If this system becomes restricted, it makes it difficult to refill the gas tank.
Did you know this problem can be caused by spiders?
Take the vehicle to a shop and ask that they check this system.
