The invention discloses an LNG (liquefied natural gas) fuel device for a vehicle. The LNG fuel device comprises a gas supply bottle for transmitting LNG fuel of an engine, and a liquefied gas adding bottle for injecting LNG into the gas supply bottle in single direction, wherein the gas supply bottle and the liquefied gas adding bottle are respectively provided with pressurization devices for pressurizing the inner parts of the gas supply bottle and the liquefied gas adding bottle to provide liquid discharging power for a gas bottle; a liquid outlet of the liquefied gas adding bottle is connected with a metal liquid filling hose capable of relieving expansive deformation caused by liquid discharging pressure, and a liquid discharging check valve and a liquid discharging stop valve are arranged at the liquid outlet so as to control liquid discharging of the liquefied gas adding bottle; a liquid inlet of the gas supply bottle can be connected with the metal liquid filling hose and is filled with LNG by the liquefied gas adding bottle. According to the LNG fuel device, gas bottle scrap loss caused by fault of a liquidometer in the gas bottle can be reduced.
