The injector is mounted in each injector hole, and each injector has a return fuel port circulating return fuel to the outside of the injector. A fuel feeding member is mounted in each feeding hole, and each feeding member has a fuel feeding passage for circulating pressure fuel to the corresponding injector. The external surface of each feeding member and the wall of each feeding hole form a return chamber 54 communicated with the corresponding return port and the return passage. COPYRIGHT: (C)2004,JPO
