The present invention relates to a vehicular fuel supply apparatus. The main purpose of the present invention is to provide a vehicular fuel supply apparatus capable of preventing the unnecessary consumption of a flow rate and energy in a fuel pump; capable of solving the efficiency deterioration problem, the NVH problem, and the durability problem of the fuel pump; and capable of minimizing a noise generation problem in a jet pump, wherein the efficiency deterioration problem, the NVH problem, and the durability problem are due to the constant driving of the jet pump. The vehicular fuel supply apparatus according to the present invention is provided to accomplish the purpose, comprises: a fuel tank; the fuel pump supplying fuel from the fuel tank to an engine by pumping the fuel; and the jet pump moving the fuel after sucking the fuel from the inside of the fuel tank by a negative pressure formed by jetting the fuel, which is supplied from the fuel pump, through a jet nozzle, and further includes a shut-off unit selectively shutting off fuel supply from the fuel pump to the jet pump depending on the amount of the fuel inside the fuel tank.
