A fuel feed apparatus includes a lid member that plugs an opening of a fuel tank. A protruding member protrudes from the lid member into an inside of the fuel tank. A sub-tank is accommodated in the fuel tank. The sub-tank is axially movable relative to the lid member. A pump module is accommodated in the sub-tank. The pump module includes a fuel pump and a fuel filter. The fuel pump pumps fuel from the fuel tank. The fuel filter circumferentially surrounds the fuel pump for removing foreign matters contained in fuel discharged from the fuel pump. A supporting member connects the pump module with the sub-tank. The supporting member extends inwardly with respect to a substantially radial direction of the sub-tank. The supporting member defines a recess on a side of the lid member. The protruding member is adapted to be inserted in the recess.
