Patent ID: 7520293

Claim:
A fuel storage system for a vehicle comprising: a fuel tank having a wall defining a fuel chamber for containing a liquid fuel; a vapor dome of the fuel chamber located between a surface of the liquid fuel and the wall when the fuel tank is in its normal attitude when the vehicle is on a horizontal plane; and a fuel vapor assembly having: a conduit extending through the wall, a buoyant vapor vent valve constructed and arranged to be in an open position when the vapor vent valve is floating upon the fuel surface and generally in the vapor dome and constructed and arranged to be in a closed position when the vapor vent valve is at least partially submerged by a predetermined distance in liquid fuel and against a biasing buoyancy force from below the vapor vent valve, and an elongate flexible fuel vapor tentacle extending between the conduit and the vapor vent valve for the flow of fuel vapor out of the fuel tank when the vapor vent valve is in the open position, received in the interior of the fuel tank, and constructed and arranged to restrict the vapor vent valve from flipping a complete one hundred and eighty degrees with respect to the fuel tank.
