What can fail
Cracks can form in the fuel vent hose. When the tank is overfilled, the vehicle is driven briefly after refueling, and the fuel tank heats significantly, fuel can expand into the vent hose and leak. Leaking fuel near an ignition source can cause fire.
What the fix does
The fuel tank vent hose will be replaced with a new hose.
