If you found a gauge that has 2 leads, then buy it.
One of the problems with the original was that the gauge also had to be grounded.
That caused problems, since the metal to metal contact between the bottle, the hold down, the rod, the frame, etc, all had to be in good condition.
The new style, I would bet, uses a ground wire as well as the wire to the control panel.
