Fillpipe Restrictor: Description and Operation

Purpose and Operation
All vehicles are equipped with a restricted fuel filler opening which functions as follows:

^ An opening in the fuel tank filler pipe allows only non-leaded fuel nozzles to be inserted. The restrictor is a narrow opening in the filler covered by a spring steel trap door.

^ The smaller non-leaded fuel nozzle will fit through the narrow opening and push the trap door aside, allowing normal filling. Leaded fuel nozzles will not fit through the opening.

^ A closed trap door causes fuel to back up and the automatic nozzle to shut off.

^ The fuel tank filler pipe is manufactured as an assembly and must be serviced by removing and replacing with a new fuel tank filler pipe. Do not modify in any way.
