small hole in gas filler tube

There is a bracket that holds the metal part of the filler tube, about 2 feet down from the gasoline input area and it leaks a little under this bracket when i fill up. Any way to patch it without replacing the tube?
thanks

J.B.Weld or and equal, like LocTite's QuikSteel?

basically, any two part epoxy, that is hardening, not pliable after setting.
being resistant to fuel and petroleum products a plus, but since it doesn't sit in it, merely gets moist ocassionally.
