Abstract: A fuel supply device is provided for use with a fuel tank. The device comprises a mounting bracket suspended into the fuel tank. A fuel pump is mounted to the mounting bracket to pump fuel from the fuel tank to the outside of the fuel tank. A pressure regulator is mounted to the mounting bracket to regulate the pressure of the fuel led to the outside of the fuel tank from the fuel pump. A fuel return passage is defined by the mounting bracket, through which a part of the fuel pumped out from the fuel pump is led back into the fuel tank under operation of the pressure regulator. First and second suction pumps are mounted to the mounting bracket and sucks fuel from first and second given portions of the fuel tank by using a power possessed by the fuel flowing in the fuel return passage. First and second passages extend from the fuel return passage to the first and second suction pumps respectively to apply the fuel from the fuel return passage to the pumps to drive the same independently.

Abstract: A fuel supply unit includes a pump module in a fuel tank. The pump module has a cover member, a fuel pump, a fuel filter, and a suction filter. The fuel pump, the fuel filter and the suction filter are mounted on a lower portion of the cover member. Moreover, the fuel supply unit includes a chamber movably mounted to the pump module and disposed in a position to receive the suction filter for forming a fuel reservoir around the suction filter. The chamber has a suction pump for sucking fuel in the fuel tank to the fuel reservoir using fuel returned into the fuel tank. Furthermore, the fuel supply unit includes a spring between the pump module and the chamber. The spring biases the chamber toward a lower surface member of the fuel tank so as to maintain the chamber at the lower surface member of the fuel tank.
