The described structure is shown in FIG. 11 and FIG. The fuel delivery pipe 80 has a plurality of cylindrical sockets 85 (only one is shown) for receiving an outer cylinder portion of a fuel injector 83 composed of an inner cylinder 81 and an outer cylinder 82, which are mutually connected via a communication pipe 86. Connected to communicate with
They are arranged at regular intervals. These sockets
85 is made by cutting a forged product, and a part of the inner peripheral surface accepts the O-ring on the fuel injector side and burnishing process with extremely high roundness and smoothness to achieve perfect liquid tightness etc. Is given.
