## Discrepancy

A FUEL LEAK FROM THE LT WING UPPER SURFACE WAS DISCOVERED WHILE CRUISING AT FL 260.  THE AIRCRAFT WAS DIVERTED TO DFW WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 1 AND NR 3 FUEL QUANTITY PROBES LEAKING DUE TO DETERIORATED O-RINGS.  THE O-RINGS AND BACKUP RINGS WERE REPLACED IAW MM 28-40-1, CODE 3, PAGES 201-203.  FURTHER INSPECTION FOUND NO OTHER LEAKS.
