It's not your Tank that's not working, (I presume it's still holding fuel?), but the changeover valve.
The valve is an electric solenoid which not only changes the inlet lines from the 2 tanks to the lift pump, but also has electric contacts which change the reading on the fuel gauge to read the level in the tank the fuel is being drawn from.
Check to see if you have any changes at the terminals on the valve when you switch the dash switch. If you get no change at the valve, your dash switch circuit is defective.If you get polarity or voltage changes at the valve, but it does not operate, then the valve is defective.
The valves are made by POLLAK, part number 42-159. These are readily available on E-BAY US
