Hazard
In the fuel system, some high-pressure fuel pumps have an improper design that results in insufficient sealing between the pump housing and the fuel pressure regulator valve. Consequently, when fuel pressure in the pump is high during high-speed driving and similar conditions, fuel may leak from the fuel pressure regulator valve mounting point.

燃料装置において、高圧燃料ポンプの設計が不適切なため、ポンプハウジングと燃料調圧バルブ間の密閉性が不足しているものがある。そのため、高速走行時等に当該ポンプ内の燃料圧力が高い際、燃料調圧バルブ取付部から燃料が漏れるおそれがある。
Remedy
Replace the high-pressure fuel pump with a corrected part on all vehicles.
