Gasoline pumps at gas stations keep turning off when trying to fill gas tank of car. Gasoline seems to back up in opening of tank even at the slowest speed of pump.
There is a vent valve located near the fuel tank. The vent valve is part of the EVAP emission system. If the valve is obstructed or failed, air will not escape while refueling.
Has the service engine light come on at all?
Regards,
I am having the same problem with this 02 Santa Fe, the check engine light is not on, I removed the evap cannister and blew out the hoses one that seems to just be a vent hose to the inside of body, the other from the cannister to the tank some pieces of charcaol came out of this hose, should the cannister and the vent solenoid be replaced?
Yes, the canister membrane that keeps the carbon contained has apparently rupshered. Im sure the vent valve is contaminated with carbon also. You can probably try cleaning the hoses and vent solenoid, but the canister will have to be replaced.
