Gas Tank Won't Fill
Diagnostic: When you try to fill the gas tank, only about 1/10th of a gallon will go into the tank before the auto-shutoff triggers in the gas pump.
Cause: Tubes behind the flapper in the gas tank have slipped.
Details: There is a one way flapper type valve at the junction of the filler neck and the tank. This is to allow gas in but not out. There are tubes in the tank behind the valve that can slip down preventing the flapper valve from opening allowing only the filler neck to fill up then slowly seeps by the valve.
Take to your dealer with less than 1/2 tank of gas. The fix is to have the dealer secure the tubes up and out of the way of the flapper valve.
Time in Shop: Several hours.
Repair Instructions: Requires dealer repair.
Notes: None.
