Abstract

The present invention provides a fuel supply device for motorcycle, a fuel flow direction of a fuel filter setting nearby the lower side of a storing box is orientated as vehicle width direction, a fuel feeding pipe being connected to a fuel injection device from a fuel box by way of the fuel filter is configured to descend towards the fuel injection device from the fuel box always, a fuel refluxpipe for cycling overfull fuel to the fuel box from the fuel injection device is always ascending towards the fuel box from the fuel injection device, a recycle pipe branching from a part higher thanthe fuel filter at middle part of the fuel reflux pipe extends by means of be always descending to connect to the fuel filter.

Description

technical field [0001] The present invention relates to a fuel supply device of a motorcycle configured to supply fuel into an engine suspended on an underbone type vehicle body frame using a discharge pump type fuel injection device. Background technique [0002] In recent years, as a fuel supply device for motorcycles, a fuel injection type fuel supply device has been widely used instead of a conventional carburetor type fuel supply device. The fuel injection type fuel supply device includes a fuel pump and a pressure regulator, wherein the fuel pump supplies fuel from the fuel tank to the fuel injection valve (injector), and the pressure regulator adjusts the pressure of the fuel boosted by the fuel pump and adjusts the excess fuel returned to the fuel tank. [0003] Usually, in a motorcycle, due to the need of parts arrangement, the fuel pump and the pressure regulator are often integrated so as to be conveniently arranged in the fuel tank. However, the fuel pump requi...
