Summary:PURPOSE: A method for producing a LPG fuel tank is provided to make a producing process simple and reduces welding parts for increasing stability. CONSTITUTION: A cylindrical frame(20) is through a common process to be an upper panel(30) or a lower panel(40). The upper surface of the cylindrical frame for the upper panel forms holes as much as the number of valves by a punch hydraulic pressure press. The side face of the cylindrical frame for the lower panel forms holes for installing a float gauge by the punch hydraulic pressure press. Herein, the lower panel is input to a joggle bending machine to be airtight when combined with the upper panel. The upper part of the lower panel is pressurized by a supporting board and the tail end part is bend inward the joggle bending machine in regular width. The bend lower panel is also pressurized by a hydraulic pressure cylinder to be airtight when combined with the upper panel.
