## Discrepancy

SHORTLY AFTER TAKEOFF, FOR A REPOSITION MISSION, PILOT OBSERVED THE ILLUMINATION OF THE FUEL PRESSURE CAUTION LIGHT WHILE IN LEVEL CRUISE FLIGHT.  ALL OTHER INSTRUMENT INDICATIONS APPEARED NORMAL ALONG WITH ENGINE PERFORMANCE.  PILOT ALERTED BOTH AIRCREW AND AIR COMM OF THE ABORTED FLIGHT AND REQUIREMENT TO RETURN BACK TO BASE.  ACFT RETURNED SAFETY TO BASE WITHOUT ANY FURTHER INCIDENT.  BASE MECHANIC DETERMINED THAT THE NR 2 FUEL BOOST PUMP HAD FAILED.  THE MECHANIC REPLACED THE BOOST PUMP AND RETURNED THE ACFT TO SERVICE.
