PROBLEM TO BE SOLVED: To provide a gas engine fuel supply device small in sized, reduced in cost, and improved in starting performance. SOLUTION: The fuel supply device 10 for a gas engine 14 is provided with a shut-off valve 17 intercepting the flow of liquefied gas fuel when the gas engine 14 is in a stop state in a fuel supply passage wherein liquefied gas fuel supplied from a small gas cylinder 12 is gasified by a vaporizer 16, the pressure of the gaseous fuel is reduced by a primary regulator 18 and further reduced to pressure close to atmospheric pressure by a secondary regulator 21, and the gaseous fuel and air are mixed by a mixer 22 and supplied to the gas engine 14. The shut-off valve 17 is disposed upstream of the primary regulator 18 in the flow of liquefied gas fuel, and the shut-off valve 17 is provided integrally with the primary regulator 18.
