Defect
On compressed natural gas vehicles, the valve seat dimensions and O-ring hardness inside the high-pressure regulator of the fuel pressure-reducing unit are incorrect. As a result, the O-ring may deform or fracture, allowing high-pressure fuel gas to flow into the low-pressure regulator and leak to the outside through the safety valve.
Corrective action
On all vehicles, replace the high-pressure regulator with a corrected part.

状況
圧縮天然ガス車の燃料減圧装置（レギュレータ）において、高圧側減圧器内部のバルブ シート部の寸法およびオーリングの硬度が不適切なため、当該オーリングが変形又は破損 することがある。そのため、燃料ガスが高圧のまま低圧側減圧器に流出し、安全弁から外 部に漏れるおそれがある。
改善措置
全車両、高圧側減圧器を対策品に交換する。
