Abstract
A method is provided for installing a nozzle restrictor assembly in a fuel filler tube. The method comprises the steps of attaching a restrictor plate to an inner surface of the fuel filler tube, coating the restrictor plate and the fuel filler tube, and inserting a closure plate through a first slot formed in the restrictor plate so that the closure plate is positioned to block the opening. A nozzle restrictor assembly is also provided which comprises a restrictor plate sized for insertion into a fuel filler tube and a mechanism for selectively closing an opening formed in the restrictor plate upon withdrawal of a fuel filler nozzle.
