Fillpipe Restrictor: Description and Operation
PURPOSE/OPERATION
Prevents inserting fuel fill nozzles that do not dispense unleaded gasoline into the tank fill opening. The opening in the tank fill pipe is a smaller
diameter than the diameter of the leaded fuel fill nozzles. This prevents the larger nozzles from being used to add leaded fuel to the tank.
