54 Flying Cloud has what appears to be the original regulator - see attached pic. Not sure how the changeover/selector works. I have one tank which is empty and one which is not. There is a large knob on the front of the regulator. I think both tanks are currently "selected" because if I disconnect the empty tank and open the valve on the other tank propane comes out the disconnected line. If I leave both tanks connected but close the valve on the empty tank, propane flows to my appliances.
1. How do I select only one tank?
2. Does this regulator have "auto changeover" capability?
3. If I decide to replace it, what model is recommended?
I have already bought aluminum tanks to replace the rusty steel ones
