Patent ID: 7757671

Claim:
A fuel feed apparatus that supplies fuel in a fuel tank to an outside of the fuel tank, the fuel feed apparatus comprising: a sub-tank that is received in the fuel tank and has a bottom wall; and a fuel pump that is received in the sub-tank and pumps fuel in the sub-tank toward the outside of the fuel tank; wherein: the bottom wall of the sub-tank has a first passageway extending in the axial direction of the sub-tank, to which a suction jet pump unit to suction fuel in the fuel tank into the sub-tank can be selectively mounted, and the sub-tank has the bottom wall that has a second passageway extending in the axial direction of the sub-tank, to which a transfer jet pump unit to transfer fuel in the fuel tank into the sub-tank can be selectively mounted, further comprising: a transfer jet pump unit mounted to the second passageway to suction fuel in the fuel tank into the sub-tank, wherein: the transfer jet pump unit includes a second suction port that is positioned at the upstream end and is communicated with the outside of the sub-tank, and a second outlet port that is positioned adjacent to the upper edge of the sub-tank and is opened at the downstream end toward the inside of the sub-tank, and further comprising: insertion sections which are formed in such a manner that the sidewall of the sub-tank is recessed in the diametrical direction of the sub-tank so that shafts connected with a flange to cover an opening on the upper wall of the fuel tank are slidably inserted thereinto, and a step section which are formed in such a manner that the sidewall of the sub-tank is partially recessed in the diametrical direction of the sub-tank so that a sender gauge to measure the level of fuel in a fuel tank is provided in, wherein: the suction jet pump unit and the transfer jet pump are received within a space between the step section and a said insertion section of the sub-tank.
