Fuel Tanks and Fillers

All vehicles are equipped with a restricted fuel filler opening that allows only a non-leaded fuel nozzle to be inserted.

The restrictor consists of 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 narrow opening. The trap door being closed causes a fuel backup, and automatic nozzle shut-off.

The restricted fuel filler is manufactured as an assembly, and must be serviced by removal and replacement with a new filler pipe assembly. Filler pipes are not to be modified in any way.

Fill limiting is accomplished through fill pipe configuration and/or internal vent lines within the fill pipe and tank. The fill limiting system is designed to permit an air space when the tank is filled to capacity of approximately 10 to 12 percent. This air space provides for thermal expansion of fuel and is necessary for proper function of the in-tank vapor vent system. The fuel tank holds approximately 58.3 L (15.4 gal).
