PROBLEM TO BE SOLVED: To provide a liquefied gas fuel supply device capable of improving engine startability, by quickly and accurately adjusting the quantity of injection fuel when starting an engine. SOLUTION: This liquefied gas fuel supply device is provided for supplying liquefied gas fuel existing in a fuel tank 10 to a delivery pipe 6 via a fuel supply pipe 12 by an electric fuel pump 14, and has an upstream side fuel cutoff valve 16 in the fuel supply pipe 12, and has a relief valve 28 in a return pipe 24. When stopping the engine, the cutoff valve 16 is closed when the liquefied gas fuel of a pressurized liquid state exists in a storage part being a part between the cutoff valve 16 and the relief valve 28, and thus, the liquefied gas fuel of the pressurized liquid state is stored in the storage part during stopping the engine and the cutoff valve 16 is opened when starting the engine thereafter.
