Fillpipe Restrictor: Description and Operation

The fuel tank filler pipe has a restrictor. The restrictor consists of a narrow opening in the fuel tank filler pipe, covered by a spring steel trap door.
Smaller non-leaded fuel nozzles will fit through the narrow opening and push the trap door aside, allowing normal filling. Leaded fuel nozzles will not fit
through the narrow opening. Closing the trap door causes a fuel backup, and automatic nozzle shutoff.
