THE ACFT WAS RETURNED TO SVC ON APR/XE/98; APPROX 36 HRS AFTER FUEL TANK MAINT WAS PERFORMED. ON APR/XC/98; ZZZ TWR RPTED THAT ON TKOF SOMETHING WAS STREAMING FROM THE L OUTBOARD WING. VISUAL INSPECTION NOTED FUEL COMING FROM THE TOP OF THE WING. ACFT RETURNED TO ZZZ. ZZZ MAINT FOUND MISSING FASTENERS AT THE #5 FUEL PROBE; ON THE 2L FUEL TANK.
