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 sustain damage. When this occurs, fuel gas passes through to the low-pressure regulator at high pressure and may leak to the outside through the safety valve.
Corrective action
On all vehicles, replace the high-pressure regulator with the corrected part.
