<p>A fuel storage system (20) includes a tank (22), a check valve (26) having an inlet tube (28), an anti-siphon device (32) and a fuel intake tube (30). The anti-siphon device (32) includes a ring (34) defining an interior opening (38) having a diameter (54). The ring (34) abuts an upstream end of the inlet tube (28) of the check valve (26), which includes an inner diameter (56) substantially equal to the diameter (54) of the interior opening (38) of the ring (34). The ring (34) includes and supports a plurality of fins (40) within the inlet tube (28) without narrowing the inlet tube (28) to maximize fluid flow through the inlet tube (28). The anti-siphon device (32) is rotatable relative to the check valve (26) and the fuel intake tube (30). The shape, size and orientation of the fins (40) are optimized to minimize flow interruption through the anti-siphon device (32) and minimize vaporization of the fluid.</p> |
