Narrative:
Fuel venting heavily out of right wing onto ramp. Called fire trucks to guard us, and shut off pumps and engines. Towed to gate. No evacuate/evacuation or injuries, and no emergency declared. Callback conversation with reporter revealed the following information: reporter stated that he was glad that the ground personnel were there to inform him of the spill since he may not have known until sometime later in the air where he would have to divert for fuel and also possible fire problem. He also stated that there was a previous maintenance discrepancy writeup fixed prior to his assignment to that aircraft. In any event, maintenance was able to find the fuel distribution problem and then departed again after 2 hours. He further stated that he noticed after this incident that the left tank had much less quantity than the right tank indicating that the fuel distribution system was moving fuel from left to right for no apparent reason.
