I am not sure if the sender is voltage sensitive, but my Ruby (12 volt ) and the Pearl I am doing at the moment will be 12 volt also, on both I have used a pre 1974 Midget/ Sprite sender , you have to bend the arm down 1/2 inch and mount it so the float is to the right of the tank (from the front ) to avoid the float touching the baffles.
