Claims

[Claims for Utility Model Registration] 1. An inlet pipe for fuel injection and a breather pipe for regulating the maximum fuel level when fuel is injected are connected to a fuel tank, and the opening of the inlet pipe can be connected to any ordinary vehicle. In a fuel tank assembly for an automobile, the breather pipe is arranged at a position such that the fuel level is higher than the fuel level in the fuel tank, and the upper end of the breather pipe is opened to the inlet space of an inlet pipe. The lower section of the freezer pipe is opened into the fuel tank at one corner of the tank, and the lower section of the freezer pipe is extended into the fuel tank, and the lower end of the freezer pipe is disposed at a diagonal position with respect to the lower end of the inlet pipe in a plan view of the fuel tank. In addition, the upper space in the fuel tank is positioned slightly below the maximum fuel level at the time of fuel injection, and the upper space in the fuel tank is connected to the inlet space of the inlet pipe when the vehicle is in a horizontal position and the fuel is filled to the maximum fuel level. 1. A fuel tank assembly for an automobile, characterized in that a means for communicating is provided, and an inlet space of an inlet pipe communicates with a fuel adsorption device via an effervescence tube. 2. The fuel tank according to claim 1, wherein the means for communicating the upper space in the fuel tank with the inlet space of the inlet pipe is a hole provided in the lower section of the breather vipe that extends into the fuel tank. assembly. 3. The means for communicating the upper space in the fuel tank with the inlet space of the inlet pipe is equipped with a check valve that opens at a predetermined pressure, and the upper end opens into the inlet space of the inlet pipe and the lower end opens into the upper space of the fuel tank. A fuel tank assembly according to claim 1, comprising a conduit.
