If it is an emergency type situation, just swap the left/right hoses on the tank valve. NOTE: If you do this, the gauge will now show the NOT IN USE tank as the gauge is switched by the switch and not the valve.

If you have one of the older style solenoid valves, they default to a non powered side, normally the passenger side. IIRC - the motor driven ones stay on the tank last selected when power is lost.

Alternative method. Just feed the hose(s) from the drivers side tank direct to the frame pipe, bypassing the valve.
