Abstract
A fitting structure for attaching a fuel pump in a fuel tank, which includes a gasket surrounding a pump insertion hole of the fuel tank. The gasket is collapsed by a presser ring through a flange portion of the fuel pump, thus enabling the gasket to provide an effective seal between the fuel pump and the fuel tank. A nut fastened onto a bolt is used to bring a second valley portion of the presser ring into close contact with a first mount portion of a fixed side ring that has been preliminarily welded to the fuel tank, thus securely fitting the fuel pump to the fuel tank. As compared with a conventional fitting structure using a bayonet or snap fit connection, wherein the fitting structure must be turned against the gasket to be fitted into a secure position, this new fitting structure presses the gasket into place, thus avoiding the turning motion and the resulting damage that may be caused to the gasket. In addition, the new structure eliminates the possibility of applying excessive compression force to the flange portion of the fuel pump, thus preventing the possibility of causing creep distortion to the flange portion, even when the flange portion is made of a light-weight resin.
