This article supersedes TSB 06-3-13 to update the vehicle model years.
Some 2005-2007 Mustang vehicles may experience premature automatic shut off of the fuel fill nozzle. Several variables, including variations in fuel pump nozzles, fuel flow rates, and fuel flow pressure may result in the premature automatic shut off of the fuel fill nozzle making it more difficult to fill the fuel tank.
The automatic shut off in the fuel fill nozzle may trigger multiple times after delivering several gallons of fuel or it may trigger repeatedly when attempting to establish fuel flow into the fuel tank. The latter concern may be more common when adding fuel to a vehicle where the fuel level is at or above 1/2 full.
Refer to Service Procedure.
On 2005 Mustangs vehicles built before 4/26/2005 that experience premature automatic shut-off of the fuel fill nozzle more than occasionally may benefit from replacing the fuel tank with a revised design tank per TSB 05-15-12. The revised design fuel tank may reduce the occurrence of premature automatic shut off.
On 2005 Mustang vehicles built on or after 4/26/2005 and 2006-2007 model year vehicles were built with the revised design fuel tank. As a result, replacing the fuel tank on these vehicles will not change the occurrence of automatic fuel fill shut off.
Occurrences of premature shut-off may be resolved or improved by using a different filling station fuel pump. Unauthorized modifications and/or alterations to the vehicle are not reimbursable under warranty and are not recommended for this issue.
