To stably supply fuel while reducing noise caused by driving of a fuel pump, in a liquefied gas fuel supply device for supplying liquefied gas fuel to an engine by sending out the fuel to a fuel injection valve in a liquid state.
This liquefied gas fuel supply device 1A is arranged in a fuel supply system of the engine for returning surplus fuel to a fuel tank 10A by sending the liquefied gas fuel stored in the fuel tank 10A to the fuel injection valve 8 still in the liquid state by a fuel pump 11A. The fuel pump 11A is arranged outside the fuel tank 10A with a fuel sucking-in part 11a for holding the fuel once by taking in the fuel, a boosting part 11b for pressurizing the taken-in fuel, and a vapor separating part 11c for separating vapor included in the pressurized fuel from fuel. A fuel supply pipe 9A extended from the fuel tank 10A is connected to the fuel sucking-in part 11a, and is connected to the fuel tank 10A by extending a fuel return pipe 9B from the vapor separating part 11a.
