: the contact stated the vehicle's fuel cap sensor light illuminated on an intermittent basis, when the fuel cap was secure. A replacement locking cap was purchased at an independent parts store but the sensor continued to illuminate. The service dealer and manufacturer were not contacted.
I recently purchased a 2006 Mustang and on the two occasions I have had to put gas in the tank, both times prior to the pump discharge shutting off, fuel has spewed out of the filler neck and down the side of the car. I have used two different stations with the same results. I also talked to a coworker who owns a 2005 Mustang and he has the same problem, and only avoids the problem by putting in a few dollars worth of gas at a time. Never filling up. I'm worried that my daughter who frequently drives the car, could be placed in a bad situation should a fire break out. Especially when it gets warmer outside.
When filing gas tank with the fuel nozzle set for fast delivery, the gas overflows onto the car. It does not trigger the automatic shutoff on the fuel nozzle. Dealer indicated that this is the "new" tank design which consists of two chambers. The rightmost chamber fills first and then overflows into the second chamber. This has occurred at several different gas suppliers, different brands, and even different states. The only way to guarantee that there will not be overflow onto the car is to check the gallons used and slow down the flow so that the nozzle trigger gets tripped. Dealer has no fix for the problem at this time.
: the contact stated when attempting to fill the gas tank with gasoline, and once the tank is half full, the gas will back up through the filler neck and spill out of the spout onto the vehicle. This is intermittent in nature. The vehicle has been seen by a dealer. The dealer determined the filler neck was functioning normal. However, the service department instructed the contact to use a different gas station that offered a different type of gas pump nozzle. The dealer's service department suspected the gas pump was forcing the gasoline into the tank at a high rate which resulted in the leak. The contact did as instructed by the dealer, but when attempting to fill the tank, the same problem occurred.
