It doesn't take flame to ignite gas fumes... just any object beyond ignition temperature.
I have an old set of very large soldering irons, one at least 1.25" in diameter. About the size of a soldering copper, and I've used them for soldering copper roof and window flashing. I suppose I could try it for gas tank repair, although I had sort of set my mind on doing it with a torch.
