Defect
On compressed natural gas vehicles, the valve seat dimensions and O-ring hardness inside the high-pressure regulator of the fuel pressure-reduction unit are incorrect. This causes the O-ring to deform or sustain damage. As a result, fuel gas passes through the high-pressure regulator at elevated pressure and may leak to the outside through the safety relief valve.
Corrective action
Replace the high-pressure regulator with the corrected part on all vehicles.
