PROBLEM TO BE SOLVED: To attain an excellent engine startability at low temperatures while preventing manufacturing cost from being raised by simplifying the structure in a fuel supply device of a gas engine. SOLUTION: This fuel supply device of a gas engine comprises a regulator 3 having a pressure regulating chamber 3a and a back pressure chamber 3b connected to each other through a fuel storage container and divided through a diaphragm 31 and feeding a gas fuel introduced into the pressure regulating chamber 3a after regulating its pressure to a predetermined one, and a fuel supply pipe 7 for connecting the regulator 3 to the mixer part 2a of an intake passage 2. A pulse pressure introduction pipe 8 for introducing pulse pressure from the engine 1 side of the regulator 3 is connected to the back pressure chamber 3b side of the regulator. At least in a predetermined timing during the start of the engine, the feeding of the fuel is promoted by assisting in displacing the diaphragm 31 by a pulse pressure from the engine 1.
