A fuel storage system includes a tank, a check valve having an inlet tube, an anti-siphon device and a fuel intake tube. The anti-siphon device includes a ring defining an interior opening having a diameter. The ring abuts an upstream end of the inlet tube of the check valve, which includes an inner diameter substantially equal to the diameter of the interior opening of the ring. The ring includes and supports a plurality of fins within the inlet tube without narrowing the inlet tube to maximize fluid flow through the inlet tube. The anti-siphon device i...
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; andat 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 di...
