摘要

PROBLEM TO BE SOLVED: To provide a high pressure fuel injection pipe for a diesel engine for facilitating and speeding up installation work, and superior in sealing performance. SOLUTION: This high pressure fuel injection pipe for the diesel engine is formed by engaging the outside end part vicinity of an outer tube with a fastening nut by interposing a seal ring member by respectively putting, and lapping the outer tube composed of a separate body on the outer peripheral side of an injection pipe body for incorporating the fastening nut into both side end parts in a connecting head part and the rear of the connecting head part.
