[0003] However, when the above-mentioned structure in which the fuel pump is arranged in the fuel tank is adopted, the height and the width of the fuel tank become larger depending on the position where the fuel pump is arranged, resulting in an increase in the size of the fuel tank.
For example, as described in the above publication, when the fuel pump is erected on the center of the bottom wall of the saddle fuel tank, the height of the fuel tank may become large.

In a fuel-feeding device for a two-wheeled motor vehicle, a fuel tank (20) is mounted on a main pipe (6a)(vehicle body frame) extending in the forward-backward direction of the vehicle, a tunnel-like recess portion (22a) through which the main pipe (6a) is inserted is formed in the central portion in the vehicle width direction of a lower tank (bottom wall portion)(22) of the fuel tank (20), and a fuel pump (26) for feeding a fuel to the engine is provided in the fuel tank (20). The fuel pump (26) is provided at a bottom center portion (22b) such that the axis (L) of the pump (26) is oriented in the forward-backward direction of the vehicle, and a fuel filter (27) is provided at a bottom side portion (22c) that is a step below the level of the fuel pump.
Description
technical field [0001] The present invention relates to a fuel supply device in which a fuel pump is installed in a saddle-shaped fuel tank mounted on a frame of a motorcycle. Background technique [0002] Some recent motorcycles include a fuel supply device for injecting fuel pressurized by a fuel pump to the engine through a fuel injection valve. In this case, although it is conceivable to install the fuel pump outside the fuel tank, once it is installed, it is necessary to ensure the airtightness around the regulator attached to the fuel pump and to make sure that the air from the regulator Since the high-pressure fuel returns to the piping of the fuel tank, it is difficult to ensure the above arrangement space. Therefore, conventionally, the fuel pump has been arranged in the fuel tank (refer to JP-A-2002-293281). [0003] However, when the fuel pump is disposed in the fuel tank as described above, the height and width of the fuel tank become large depending on the pos...
