Narrative:
Crew called at the gate and requested deferral for the #3 fuel quantity indicator. The crew was not familiar with the MEL book procedures. I spent time to explain and did not notice the fuel flow inoperative. Cannot defer the fuel quantity and the fuel flow indicator. I noticed my error and had the aircraft repaired. I was distracted by the crew and failed to read the MEL and review the history of deferred items.
