Abstract

The present invention provides a fuel supply apparatus, wherein relative to a fuel pump inside a fuel box, a fuel filter is arranged outside the fuel box, thereby increasing the assembling property of the fuel box on vehicle body. A fuel pump (22) is configured inside the fuel box from the bottom (24) of the fuel box (20), and the fuel filter (41) is arranged at the bottom (22b) of the fuel pump (22).the rear lower end of a carrying bracket (51) carrying the fuel filter (41) is located lower than the fuel filter (41).

Description

technical field [0001] The present invention relates to a fuel supply device suitable for saddled vehicles such as motorcycles. Background technique [0002] In the past, in the above-mentioned fuel supply device, if relying on fuel with fine particles such as ethanol gasoline (ethanol), in order to lengthen the replacement cycle of the fuel filter, there is a finer filter on the downstream side of the coarse primary filter. In the case of a secondary filter (for example, refer to Patent Document 1.). In this aspect, the secondary filter (143) arranged on the downstream side of the fuel passage compared to the fuel pump (92) is set so that the mesh ratio is arranged on the upstream side of the fuel passage compared to the fuel pump (92). The primary filter (141) is thin, and the secondary filter is covered with a housing (143A) and installed along the center frame (23) of the motorcycle via a bracket (146). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2008-248...
