The reproduction 12v gas gauge on my '54 does not return to Empty when the ign is off. It floats to where ever gravity pulls it. Since it is on the top right corner of the cluster, it floats to Full. None of the 12v reproduction gas gauges that I have seen in catalogs are sitting on Empty. It must be the nature of the gauge. The guts of my 12v gauge look totally different to the guts of the original 6v gauge.
I think that your problem is deeper than the design of the 12v gauge.
