I have tried popping dents with air pressure. Popped the dent just fine on a
tank thinner than the vanagon tank.  I wouldn�t do it on a vangon tank for
two reasons.  The gauge of the tank and even on the thinner tank we did it
on we were at about 80 psi and it was on a buckle more than a dent.  The
tank leaked like a seive when we finished.

So the short story is don�t do it.  The dent probably don�t take up enough
volume to worry about any way.
