PROBLEM TO BE SOLVED: To provide a fuel supply device of an engine for models which can operate the engine for models stably regardless of the flight attitude. SOLUTION: A silencer 2 connected to the engine 1 for models and a fuel tank 5 are coupled by a pressure introduction tube 4, and the pressure of exhaust gas discharged from the silencer 2 is introduced into the fuel tank 5 so that pressurized fuel is supplied to a carburetor 3 from a fuel supply tube 9. Two exhaust ports 6, 7 are formed in the pressure introduction tube 4. One exhaust port 6 is positioned within a pressurized room 8, and the other exhaust port 7 is positioned in the fuel. As a result, no matter how the fuel tank 5 is postured, one of the exhaust ports can be positioned inside the pressurized room 8, thereby stabilizing the operation of the engine 1 for models.
