## Discrepancy

THE MECHANIC INSTALLED MODULE.  DURING INSTALLATION THE FUEL INLET UNION PIPE AND B-NUT, THE MECHANIC NOTICED THAT THE FUEL PRESSURE UNION MOVED.  IT WAS IMMEDIATELY APPARENT THAT THIS UNION HAD NOT BEEN TORQUED.  UPON A VISUL INSP OF THE UNION, THE CRUSH GASKET DID NOT APPEAR TO BE SEATED AND THE MOUNTING HARDWARE SHOWED ONLY A .5 THREAD COUNT.  IAW THE CURRENT MM TASK FOR THE INSTALLATION OF THE UNION 72-43-00-900-805-B01.  THE TASK REFERENCES THE STANDARD TORQUE FOR THE HARDWARE CONTAINED IN CHAPTER 70-41-00-850-801.
