Narrative:

Approximately 45 min after takeoff, at an altitude of FL330, the captain phoned me and stated that an indicator light in the cockpit and the fuel gauge for the left wing fuel tank showed the tank to be rapidly losing fuel, nearing empty. He asked me to proceed to door 3L and make a visual check out of the window to see whether I could detect a vapor trail or contrail of the leak. I could not. The captain deemed the situation serious enough to turn back to jfk, but stated no evacuate/evacuation would be necessary. We landed safely, without incident or injury, and changed aircraft and continued on with our trip.
