Hazard
Fuel piping has inadequate cleaning during manufacturing, leaving oxidation film residue on the pipe surface, which causes poor adhesion of the brazing solder used as adhesive. Continued use in this condition may result in cracks developing in the brazing solder at the pipe connection and pipe end due to fuel pressure, potentially leading to fuel leakage in the worst case.

燃料配管において、製造時の洗浄が不適切なため、配管表面に酸化皮膜が残留し、接着剤であるロウ材の接着が不良となっているものがある。そのため、そのままの状態で使用を続けると、燃料の圧力によって配管接続部及び配管端部のロウ材に亀裂が発生し、最悪の場合、燃料が漏れるおそれがある。
Remedy
All vehicles: Replace the fuel high-pressure rail with a new part.
