## Discrepancy

THE NUMBER 1 FUEL TEMP WAS DROPPING FOLLOWED BY THE ILLUMINATION OF THE NR 1 HYD ISO VALVE CAUTION LIGHT.  THE HYD QTY WENT TO .5 QT.  THE NUMBER 1 FUEL PRESSURE CAUTION LIGHT ILLUMINATED BUT THE FUEL FLOW WAS NORMAL.  THE CREW TURNED ON THE AUX PUMP AND THE NR 1 FUEL PRESSURE CAUTION LIGHT WENT OUT.  AN EMERGENCY WAS DECLARED AND THE FLIGHT LANDED WITHOUT INCIDENT.  HYD FLUID WAS LEAKING FROM THE RIGHT SIDE.
