Service bulletin CYL-TSB-004
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
CYLINDER BRACKET AND STRAP INSTALLATION A NUMBER OF CYLINDER BRACKET ASSEMBLIES ARE AVAILABLE FROM VARIOUS MANUFACTURERS THAT CAN BE USED TO SECURE THE QUANTUM TYPE 4 GASEOUS FUEL CYLINDERS TO A VEHICLE. THESE BRACKET ASSEMBLIES MUST BE PROPERLY ASSEMBLED AND INSTALLED. IF THE CYLINDER BRACKET ASSEMBLIES ARE IMPROPERLY INSTALLED OR THE PRELOAD APPLIED TO THE CYLINDER STRAPS IS INCORRECT, THE CYLINDER BRACKET ASSEMBLY CAN FAIL TO PROPERLY RETAIN THE CYLINDER. IF THIS OCCURS A FUEL LINE MAY LOOSEN OR FATIGUE DUE TO CYLINDER MOVEMENT OR THE CYLINDER COULD BE DAMAGED. EITHER SCENARIO COULD LEAD TO A FUEL LEAK CREATING A FIRE HAZARD. IMPROPER CYLINDER BRACKET ALIGNMENT OR STRAP PRELOAD MAY RESULT IN UNEVEN PRESSURE BEING APPLIED TO THE CYLINDER STRAP ISOLATOR. THIS UNEVEN PRESSURE MAY RESULT IN PREMATURE ISOLATOR FAILURE, DAMAGE TO THE CYLINDER AND OR CYLINDER BRACKET ASSEMBLY. THE PRELOAD APPLIED TO PROPERLY SECURE THE CYLINDER IN THE BRACKETS WILL VARY DEPENDING ON THE CYLINDER MANUFACTURER AND OR CYLINDER BRACKET MANUFACTURER.
