Narrative:

Center tank fuel boost pumps checked good on ground. Recognized in-flight boost pump failure. Ran fuel and checklist. Called maintenance controller, declared emergency for minimum fuel. Diverted to las and landed there uneventfully, with approximately 4000 pounds usable wing fuel. Emergency terminated. Total unusable center tank fuel approximately 10000 pounds. Landing weight 124000 pounds. Fuel log detected failure at third fuel log fix where center fuel first indicated same as second fix. Checking main tank fuel in addition to center tank fuel at all fuel log fixes will now be a priority and would have helped detect failure at second fuel log fix.
