ok, another question.... how does the tank selector valve work specifically related to the power to it and how does it move to open/close either tank when switched at the dash switch? what turns switch "off" when needed after tank selected. finally how can "a guy" check/verify the selector valve is "switching fully" when activated by the dash switch??

thanks!!
