PROBLEM TO BE SOLVED: To ensure a preferable low-temperature start performance of the engine in an LPG fuel supply device for an engine utilizing the heat of an electric heater in addition to the utilization of the heat of engine cooling water for heating the vaporization of an LPG fuel. SOLUTION: The LPG fuel supply device for an engine comprising a heating vaporization means 3 for heating vaporization of an LPG using an electric heater 31 in addition to the heat of engine cooling water circulating through engine cooling water circulation paths 8a, 8b is provided with a shut-off valve 15 and a temperature sensor 13 as a cooling water temperature sensing means in the engine cooling water circulation path 8a so that a circulation of the engine cooling water to the heating vaporization means 3 is stopped at the time of the low-temperature start of the engine by keeping the shut-off valve 15 in a closed state by an electronic control unit 10A from the start of the power supply to the electric heater 31 until the engine cooling water temperature reaches to a preset temperature.
