PURPOSE:To make it possible to rapidly generate a fuel gas having a nearly uniform density so as to simplify the restart of an engine by installing a porous member and a float on the end of a flexible air introduction hose which is used for introducing the air through a check valve in a fuel tank. CONSTITUTION:Fuel gas 39 is filled with a fuel tank 34 at the time of stoppage of an engine at high temperature. In this condition, when the opening/closing valve 7 of a restart fuel feeding mechanism 15 is pulled open, fuel gas 3, 9 enters a passage 12 through an exit 32, a hose 1 and a jet 2 and sucked together with the air from an air inlet port 4 into the inside of an intake pipe 21 through a hose 14 by an intake vacuum pressure and supplied to an engine, therefore the restart of the engine comes to be carried out easily. Then, a porous member 37 positioned at the end part of a flexible air introduction hose 38 for introduc ing the air into the fuel tank 34 is floating right below the fuel liquid surface by the function of a float 35, and when the outer air is sucked resulting from the pressure drop inside the tank 34, the air becomes bubbles resulting in promot ing atomization and evaporation of fuel.
