ABSTRACT:
An anti-siphon fuel filler assembly having restriction means therein for preventing unauthorized fuel removal is provided. In addition, back pressure relief means are provided for preventing the premature deactivation of automatic fuel dispensing systems caused by reverse fuel flow. The back pressure relief means includes a plurality of side openings and tabs extending outwardly from the edges of such side openings to deflect fuel out of the side openings when such fuel splashes upward from the restriction means. The invention may be used as an insert, fixedly positioned within an existing filler neck tube. In the alternative, the invention may be an anti-siphon filler neck tube used as an original equipment component for new vehicles, replacing the conventional filler neck tube.
