Hazard
The fuel pressure sensor mounting surface on the engine fuel delivery pipe has inadequate surface finish. Even when the fuel pressure sensor is tightened to the specified torque, clamping force may be insufficient. This can cause the fuel pressure sensor mounting to loosen, potentially resulting in fuel leakage.

原動機の燃料配管（デリバリパイプ）において、燃圧センサ締結面の平滑度が不適切なため、燃圧センサを規定トルクで締め付けても締結力が不足しているものがある。そのため、燃圧センサ締結部がゆるみ、燃料が漏れるおそれがある。
Remedy
For all vehicles, polish the fuel pressure sensor mounting surface on the delivery pipe, replace the gasket with a new one, and properly tighten the fuel pressure sensor.
