A fuel supply structure for a saddled vehicle, includes: an upstream-side fuel supply system guiding fuel from a fuel tank to a fuel pump side; a downstream-side fuel supply system guiding the fuel from the pump to a fuel injection valve side; and an excess fuel return system returning excess fuel from the downstream-side fuel supply system to the tank side. A fuel hose joint is attached to the tank and includes: an insertion tube portion inserted into the tank and formed into a dual tube structure where an inner tube is covered by an outer tube; a first connection tube portion communicating with inside of the inner tube; and a second connection tube portion communicating with inside of the outer tube. A fuel suction hose is connected to one of the first and second connection tube portions, and a fuel return hose is connected to an other thereof.

Fuel supply structure for saddled vehicle

In a saddled vehicle, an internal combustion engine is disposed below a fuel tank and a riding seal disposed behind the fuel tank. A fuel pump is supported by a front body frame that suspends a front wheel, the fuel pump being disposed at a position where at least part of the fuel pump overlaps with the front wheel as seen in a side view. The fuel tank is supported on an upper frame member that configures part of the body frame. A protection member is extended between the upper frame member and the front body frame, and passes a front of the engine body as seen in a side view. A fuel suction pipe line is covered by the protection member from an outer lateral side and locked to the protection member, the fuel suction pipe line sucking fuel form the fuel tank to the fuel pump side.

Saddled vehicle

In an evaporated fuel control device for a saddled vehicle, a canister and an evaporated fuel control valve are supported by a body frame around a fuel tank, the canister adsorbing evaporated fuel from the fuel tank, the evaporated fuel control valve controlling a flow rate of the evaporated fuel that is purged from the canister and flows through an intake system of the internal combustion engine. The canister is disposed between a steering shaft and the fuel tank and below an imaginary horizontal plane that passes a lowermost surface of the fuel tank, the steering shaft extending in an up-down direction while inclining downward to a front in front of the fuel tank.
