## Discrepancy

AFT (UPPER) FUEL XFEED SWITCH 'VALVE' LIGHT INOPERATIVE.  MM COMMENTS:  TOP FUEL CROSSFEED VALVE LIGHT DOES NOT COME ON WHEN ACTUATED.  LIGHT INOP, CONFIRMED OPERATION PER MEL.  FOUND WRONG SWITCH INSTALLED.  NEEDS LENS CAP 563-3644, MASTER MODULE 563-3385 & CIRCUIT CARD 563-3969. LENS CAP NON STOCK SEATTLE. POST COA 505010. FWD CROSS FEED VALVE LIGHT IS INTERMITTENT.  NEEDS SAME PARTS AS AFT CROSSFEED VALVE.  LENS CAP NON-STOCK SEATTLE. VERIFIED BOTH CROSSFEED VALVES OPERATE PER MEL.  REPLACED ACT PER MM.  LIGHT AND ACT OPS CHECK OK NOW.
