Fuel supply apparatus for vehicles

Abstract

PROBLEM TO BE SOLVED: To improve assemblability of a fuel tank to a vehicle body, while providing a fuel filter outside the fuel tank with respect to a fuel pump in the fuel tank, in a fuel supply device of a vehicle.SOLUTION: The fuel pump 22 is arranged inside the tank from a bottom 24 of the fuel tank 20, and the fuel filter 41 is attached to a bottom 22b of the fuel pump 22. A rear-lower end t1 of a bracket 51 supporting the fuel filter 41 is positioned 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).
