Narrative:
En-route we noticed a fuel imbalance of approximately 1;400 pounds low on left side. We balanced the fuel and continued. We noticed fuel imbalance starting again (low on left side). We ran engine fuel leak procedure and asked deadheading captain to check evidence of fuel leak. He was unable to verify a leak. We declared an emergency and diverted to an en route airport. We were in an idle descent until final approach and did not notice additional increase in the imbalance at that time. We landed on runway 01L and shut down left engine after clearing the runway. The airfield rescue and firefighter crew said they saw evidence of a fuel leak and we pulled left fire handle. After cleared from airfield rescue and firefighter crew we taxied to remote parking and deplaned the passengers.
