ABSTRACT:
A fuel feed apparatus includes a sub-tank and a fuel pump that are received in the fuel tank. The sub-tank has an inner space that is partitioned into at least a first chamber and a second chamber. The fuel pump is arranged in the first chamber to discharge fuel received in the sub-tank to the outside of the fuel tank. The second chamber has an opening, through which the second chamber communicates with the outside of the sub-tank such that fuel accumulated in the second chamber is exhausted to the outside of the sub-tank through the opening. The fuel tank has a first tank space and a second tank space. The sub-tank is received in the first tank space. A first jet pump is disposed in the second chamber of the sub-tank. The first jet pump draws fuel accumulated in the second tank space into the first tank space.
