In this case the stuck gauge was caused (I'm of course Monday morning
quarterbacking) by the overpressure in the fuel tank, which was caused
by the aux fuel system.

I find it difficult to believe that the pressure in the wing tank(s)
was significant, but if it were, imagine what might have happened if
the fuel bladder(s) had ruptured, worse yet, if the hydraulic pressure
of the fuel against the wing structure had started popping rivets!
