An insert adapted to rebuilding restrictor assemblies in the fuel filler neck of non-lead gasoline automobiles which comprises an oblong piece of metal formed with sharp corners that may be swedged into the restrictor assembly with an aperture therethrough aligned to the restrictor aperture. The insert serves to down-size a mutilated restrictor aperture to the proper diameter for fit to the standard nozzle of unleaded gasoline dispensers.
