I think someone must have tightened the hell out of this plug years ago.
The tanks are 3/16 steel plate, and the plug is mounted in a very heavy
boss.
I think that an impact extension could be mig-welded into the plug
and it could be turned.

The only problem might be my hands shaking too bad to get a decent bead.

My neighbor said: "Go on and weld the damn thing. Hell, she aint goin'
to make but one bang!".

It'll be fine. Remember the fire triangle. You have to have fuel, oxygen,
and heat all come together at the same time in the same location. The
plug is under liquid gasoline, so oxygen is missing from the fire
triangle.
Some of the gas will boil, raising the vapor pressure in the tank. But it
will be below ignition temperature when it finds the vent. You will have
a flamable mixture just outside the vent, make sure you don't throw any
sparks that way. (You might want to run a hose from the vent to some
point downwind of your activities.)

Wonderful theory. Remind me to stand back a long way while you
try it. I will use my video camera (the long distance telephoto lens is
pretty good). This is one of those things that sound great in theory
before the fact, afterwards no one can explain what happened. ;-(
