Zusammenfassung:	PROBLEM TO BE SOLVED: To increase the efficiency of a force feed pump by making the pump impeller of the force feed pump arranged in a pump chamber larger in diameter than a central chamber, and directly feeding the fuel flow from the force feed pump to an annular chamber. SOLUTION: A casing 3 is provided with an electric motor, a fuel main filter 8 in an annular chamber, and a force feed pump having a pump impeller 6 in a pump chamber 14. The annular chamber is partitioned into an outside region and an inside region by a seal member 18. The pump impeller 6 has a diameter nearly reaching the region of the outer diameter of the casing 3. The fuel force-fed by a force feed pump via an overflow opening section 29 is directly force-fed to the outside region of the annular chamber from the pump pipeline of the pump impeller 6.
