To provide a high pressure fuel delivery pipe assembly for a direct injection engine, hardly causing fuel leakage while reducing a manufacturing cost by reducing the number of components.

In a high pressure fuel delivery pipe assembly 10 for a direct injection engine, a plurality of composite blocks 11 each having a cylindrical body part 12 formed integrally with a socket part 20 and a mounting boss part 30 are arranged on a straight line and connected with one another. Each socket part 20 is communicated with a fuel passage fa of the body part 12, and each mounting boss part 30 is separated from a center line in the longitudinal direction of the body part 12 so that its mounting hole 31 is not communicated with the fuel passage fa of the body part 12.
