Narrative:

The #3 fuel tank was initially overfilled and fuel was dripping out of the vent scoop. When I arrived at the aircraft, under authority/authorized of air carrier airlines maintenance controller, I accomplished a visual inspection of the #3 fuel tank vent scoop and found no leakage. Controller and myself assumed the fuel in the surge tank will gravity feed through the check valve. The aircraft taxied off the gate. Due to the movement of the fuel during taxi, the fuel once again started leaking out the vent scoop. The aircraft returned to the gate. I once again contacted maintenance. I explained the situation to the new shift controller abc xzw who notified me that they will send air carrier maintenance from XXX to accomplish a check of the drain check valve.
