## Discrepancy

ENROUTE FROM TUL TO IAH RECEIVED A HYD2 LOW QTY INDICATION ON EICAS.  THE MESSAGE CLEARED, BUT THE CAPTAIN CHECKED THE HYDRAULIC PAGE TO ENSURE NORMAL OPERATION.  UPON ENTERING THE PAGE, HYDRAULIC SYSTEM 2 INDICATED 0 PERCENT QUANTITY WITH 2500 PSI.  THE FIRST OFFICER FOLLOWED THE QRH AND THE FLIGHT DIVERTED TO DAL AND LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE ENGINE DRIVEN HYDRAULIC PUMP CASE LEAKING.  THE PUMP WAS REPLACED AND OPERATIONALLY CHECKED GOOD.  LEAK CHECKS WERE GOOD AS WELL.
