Defect summary
SOME CHASSIS WERE SHIPPED TO BODY BUILDERS WITH DAMAGED FILL OR VENT OPENING CAPS ON THE RIGHT-HAND SIDE. IF A LEFT-HAND FILL SYSTEM WAS INSTALLED ON THE TANK, AND THERE WAS A DAMAGED RIGHT-HAND CAP, THE FUEL SYSTEM WOULD NOT BE SEALED.
Consequence
IF THE FUEL SYSTEM IS NOT SEALED, THE AUTOMATIC SHUT-OFFSYSTEM USED IN GAS STATIONS WOULD NOT WORK, ALLOWING GAS TO BE FORCED OUT OFTHE DEFECTIVE RIGHT-HAND OPENING. THE SPILLED GASOLINE WOULD RESULT IN A FIREHAZARD IF EXPOSED TO A SOURCE OF IGNITION.
Remedy
INSTALL NEW CAPS ON THE VEHICLES WITH UNUSED RIGHT-HAND FILL OR VENT OPENINGS.
