Abstract:
1. An anti-siphon device for a fuel storage system, the anti-siphon device comprising: a ring concentric with a longitudinal axis and defining an interior opening; at least one fin spanning across the interior opening of the ring and having a depth extending away from the ring along the longitudinal axis; and at least one projection extending inward from the ring into the interior opening of the ring; wherein the interior opening of the ring defines a diameter and wherein the ring abuts an end of a tube having an inner diameter substantially equal to the diameter of the interior opening of the ring such that the ring supports the at least one fin within the tube without substantially narrowing the inner diameter of the tube, thereby minimizing a fluid pressure drop through the tube during refilling; and wherein the at least one fin and the at least one projection cooperate to prevent passage of an object having an outer diameter of at least 5.0 mm from passing through the interior opening of the ring.
