Narrative:
Departed and on climbout through FL200 fuel imbalance noticed; left fuel quantity decreasing rapidly (approximately 10 pounds a second). First officer ran QRH procedure for fuel imbalance. This led to QRH procedure for suspected fuel leak. Shutdown left engine per checklist. Declared emergency with center; completed in-flight shutdown; prepared cabin crew and passengers for single engine divert to a nearby field. Notified local airfield rescue and fire fighters to be standing by. Executed RNAV approach. Uneventful landing; stopped on runway for airfield rescue and fire fighters to inspect aircraft. No leak found; tugged to gate. There was a time delay in being informed if there was a leak by the local airfield rescue and fire fighters due to no ground to cockpit communication. The information had to be relayed by the tower. This led to some initial confusion but was quickly resolved by opening the cockpit window to get their attention.
