## Discrepancy

AN ODOR OF FUEL IN THE NR 2 ENGINE COMPARTMENT, AND NOTICED THE ENGINE DECK HAD FUEL ON IT.   DRIP FROM THE STARTING DRAIN VALVE DRAIN LINE.  FOUND LEAK COMING FROM THE UNION BETWEEN THE STARTING DRAIN VALVE, AND IGNITION SOLENOID VALVE.    FOUND O-RING HAD NOT PROPERLY SEATED.  REMOVED O-RING, AND INSTALLED IT IAW MANUAL.  OPS AND LEAK CHECKED GOOD.
