PROBLEM TO BE SOLVED: To provide a fuel injection device for a liquefied gas engine generating no rust in an injector even if it is left to stand over a long period of time after stopping of the engine. SOLUTION: The fuel injection device for the liquefied gas engine is provided with a purge means (purge line 8 having purge control valve 7) for removing out a fuel in a fuel injection system after stopping of the engine. The device is provided with an addition vessel 12 for pressurizing/retaining a lubrication improving agent 11 having high viscosity and low volatility and is constituted such that the addition vessel 12 is connected to the midway of an injection line 5 for leading the fuel to the injector 6 through a flow passage switching valve 14, the flow passage switching valve 14 is switched and the lubrication improving agent 11 can be pressure-fed to the injector 6 after removal out of the fuel from the inside of the fuel injection system by the purge means.
