Fillpipe Restrictor: Description and Operation

Fuel Filler Neck

Fuel Door And Restrictor (Typical)

Purpose

To prevent refueling with leaded fuel, the fuel filter neck has a built-in restrictor and deflector. The opening in the restrictor will accept only the
smaller unleaded gasoline fuel nozzle which must be fully inserted to bypass the deflector.
