摘要： A fuel feed apparatus, which is accommodated in a fuel tank, includes a sub-tank, a jet pump, and a covering member. The sub-tank includes a fuel inlet. The jet pump includes a jet nozzle, through which fuel is jetted to generate negative pressure, so that fuel in the fuel tank is drawn into the sub-tank through the fuel inlet. The covering member covers a gap formed between the jet nozzle and the fuel inlet. The covering member is opened on the bottom side of the gap. The covering member downwardly extends from the upper side to a gap-lower end position. The gap-lower end position is located on the upper side with respect to the center of the jet nozzle by a distance that is equal to or greater than 1 mm, and is equal to or less than 2 mm.
