Same here. When I weld bike tanks I pump compressed air through the petcock
hole and work with the gas cap off and the hole pointed in a safe direction.
With a constant air flow fumes can't build up and the worst you're going to
get is a flash out where the air is escaping. I've done this dozens of
times with only a couple flashes like I was expecting not that it doesn't
startle me when it happens.

I don't know how big your tank is but if you can freeze it (-0 F.) then you
should be able to get the J.B. Weld to break out easily.

An interesting idea.
My fridge won't do that low.
Maybe a box full of dry ice?
