## Discrepancy

LEFT FUEL LOW PRESSURE LIGHT CAME ON. CREW CARRIED OUT CHECKLIST, RT LOW FUEL PRESSURE LIGHT LIGHT ON WHEN CROSSFEED VALVE OPENED. IMBALANCE OF FUEL WAS NOTED, AUX FUEL WOULD NOT TRANSFER CROSSFEED VALVE CLOSED, BOTH FUEL LOW PRESSURE LIGHTS EXTINGUISHED. THEN LT FUEL LOW PRESSURE CAME BACK. AIRCRAFT DIVERTED. MAINTENANCE POINTED TO INTERMITTENT AND/OR DEFECTIVE VENTRAL TANK REFUEL/DEFUEL VALVE.
