Abstract

This fuel system is composed of a bottom plate for closing an opening in the bottom surface of a fuel tank and a side wall part integrally formed with the bottom plate, and a space in the side wall part has a flange forming a sub tank in the fuel tank. A fuel pump, a strainer and a pressure regulator are arranged in the space in the side wall part, and return fuel in the pressure regulator is returned to the inside of the sub tank. A cover with a connecting member equipped with a fuel channel for connecting the fuel pump with the strainer is attached to the upper part of the side wall part. The connecting member retains the fuel pump and the upper part of the strainer. This fuel system is compact with easy installation, and can stably supply fuel to the engine.

Description

technical field [0001] The present invention relates to an in-tank fuel supply, and more particularly to a technique ideally applicable to a type of fuel supply particularly adapted to be mounted to the bottom of a fuel tank. Background technique [0002] Generally, a so-called in-tank fuel supply device widely used in the field of motorcycles or motor vehicles includes a fuel pump and a fuel filter arranged in a fuel tank, such a fuel supply device is disclosed in Japanese Patent Application Laid-Open Document Those devices disclosed in Hei 10-213036 and Hei 8-225023. Such tank-type oil supply devices can be divided into two major categories structurally, the first category includes Japanese Patent Application Laid-Open Document Hei 10-213036, and is shown in Figure 5 The kind of device in, this kind of oil supply device is suitable for fitting on the bottom opening 52 of fuel tank 51. The second category includes those disclosed in Japanese Patent Application Laid-Open D...
