    Fuel System, Other / Storage

    Defect, in the NHTSA record
    Certain compressed natural gas fuel containers, model alt823d, p/n 1273147, equipped on certain 2003 and 2004 orion vii buses. The nvg container's pressure relief devices fail to timely and fully activate as required by federal motor vehicle safety standard no. 304, compressed natural gas fuel container integrity.
    Consequence, in the NHTSA record
    In the event of a vehicle fire with the fuel system roof enclosure removed or opened, the fuel container's pressure relief devices may not activate as they are designed to do and the fuel container could rupture and explode. Such an explosion, if it were to occur, could cause serious injuries or death to occupants of the bus or to persons outside the bus.
    Remedy, in the NHTSA record
    Structural composites will replace the pressure relief valve free of charge. Structural composites is expected to notify the owners of affected orion vii buses in june 2004. The recall began february 2005.

    Fuel System, Other / Storage / Tank Assembly / Pressure Relief Devices

    Defect, in the NHTSA record
    Some temperature sensitive triggers were not x-rayed. These triggers could contain internal voids that would make the triggers susceptible to advanced creep causing false activation and venting of the cng.
    Consequence, in the NHTSA record
    Venting of the cng could result in a fire.
    Remedy, in the NHTSA record
    Sci will replace the type III prd with a suitable replace- ment device.

    Products named: Sci Fuel Tank.

    Report filed by STRUCTURAL COMPOSITES.

  3. 95E005002Received . 15 units.

    Fuel System, Other / Storage / Tank Assembly / Pressure Relief Devices

    Defect, in the NHTSA record
    Upon exposure to impurities in the natural gas fuel in cold weather, an internal o-ring on these devices can blister during decompression after "fast-fill" refueling resulting in seal leakage.
    Consequence, in the NHTSA record
    Internal damage to the o-ring seal could cause a release of cng. If cng were released to the environment and an ignition source were present, a fire could occur.
    Remedy, in the NHTSA record
    Sci will replace recalled units with new devices that are not susceptible to o-ring damage from non-methane components of the gas supply when the devices are developed.

    Products named: Sci Alt 620N 1994; Sci Alt 584N 1994; Sci Alt 506N 1994; Sci Alt 619N 1994.
