ABSTRACT:
A restrictor adapted to replace missing restrictors of fill pipes of automobile fuel tanks. A containment ring with a reduced center opening (large enough for unleaded fuel nozzles and too small for leaded fuel nozzles) and an outer diameter smaller than the inner diameter of the fill pipe. A spring biased flap or cover, closes the center opening. Bendable tabs extend from the periphery of the ring. The tabs are bent forwardly away from the side of the flap, and the restrictor is inserted into the fill pipe at the designated position. One of the tabs is clamped against the fill pipe wall while the others are rebent into a configuration to engage the fill pipe wall. The tabs are fastened to the wall by an adhesive, soldering or welding. Soldering may be achieved by pretinning of the tab ends.
