PROBLEM TO BE SOLVED: To suppress fuel leakage of a high-pressure fuel delivery pipe for a direct injection engine, and to facilitate processing in manufacturing.SOLUTION: A high-pressure fuel delivery pipe 10 for a direct injection engine includes a plurality of cylindrical body parts 12 in which a cylindrical fuel passage f is bored in the longitudinal direction of a slender columnar body and a plurality of unit blocks 11 each integrally forming a socket part 20 and a fitting boss part 30. The unit blocks 11 are connected to the cylindrical body parts 12 on a straight line. In a unit block 11D, a fuel passage fd is bored in an inclination direction with respect to a longitudinal center axis x of a body part 12D so as not to communicate with a fitting hole 31D and to communicate with a socket hole 21D. |
