PURPOSE: To improve the fitting strength and vibration resistance of a delivery pipe by differentiating the distance from the center of a fuel distribution passage to the center of at least one pipe side fitting hole from the others.

CONSTITUTION: Pipe side fitting parts 20-1, 20-3 are provided on one longitudinal side of a body 12 in such a way that the respective centers C1, C3 of pipe side fitting holes 22-1, 22-3 are positioned on a line L1 provided parallel to a centerline L0 passing the center C0 of a fuel distribution passage 16, and spaced by the distance l1 from the centerline L0. A pipe side fitting part 20-2 is provided on one longitudinal side of the body 12 in such a way that the center C2 of a pipe side fitting hole 22-2 is positioned on a line L2 provided parallel to the line L1, and spaced by distance l2 from the centerline L0 passing the center C0 of the fuel distribution passage 16. The distances from the center C0 of the fuel distribution passage 16 to the respective centers C1-C3 of the pipe side fitting holes 18-1-1.8-3 are thus provided as different distances l1, l2.
