A fuel system of a vehicle is provided to inject fuel easily and to improve rigidity of the vehicle by installing a fuel gathering preventing path at a curvature unit of a bent tube for preventing gathering of fuel in a U-shaped trap. A fuel system of a vehicle comprises a fuel tank(100), a filler tube(200), a liquid trap(300), a bent tube(400), and a three-way valve(600). One end of the filler tube is connected with the fuel tank. A fuel injection port is formed at the other end of the filler tub, and injects fuel into the fuel tank. The liquid trap is installed in the filler tube, and injects fuel into the fuel tank after temporarily storing fuel inside. The bent tube has a bent hole(410) and a cut unit(430). The bent hole is connected with an upper part of the fuel tank to discharge vapor gas from the fuel tank. The cut unit is formed in the liquid trap. The bent tube is extended from the bent hole to inside of the liquid trap and connected with the filler tube. A fuel gathering prevention path(500) is formed at a curvature unit of the bent tube. The three-way valve is installed at the fuel gathering prevention path and opened and closed by weight of fuel. |
