<p>PROBLEM TO BE SOLVED: To provide a vehicle fuel device capable of detecting that a leveling valve is immersed in fuel level with a simple structure.SOLUTION: A vehicle fuel device comprises: a canister 50 which absorbs evaporative gas of fuel in a fuel tank 10; a leveling valve 13 which controls fuel supply to the fuel tank; a vapor passage 31 which communicates the leveling valve with the canister and guides the evaporative gas in the fuel tank to the canister; a sealing valve 35 which seals the vapor passage 31 to put the fuel tank in a sealed state; a pressure sensor 33 which is installed on the vapor passage between the sealing valve and the leveling valve and detects pressure inside the fuel tank; and an immersion determination section 38 which determines whether or not the leveling valve is immersed in the fuel on the basis of fluctuation of the pressure detected by the pressure sensor while the sealing valve is opened. Thus, the vehicle fuel device determines that the leveling valve is immersed in the fuel on the basis of sudden fluctuation of the pressure detected by the pressure sensor.</p> |
