Please give me a few minutes to get set up.
Yes you can, but you can not use the water dispenser which you can't now anyway so I guess it doesn't matter. First of all, you can order the part at the following link:
To remove the tank remove the crisper drawers and shelves. This will give you access to the tank. Remove the two screws that hold it in. Then remove the front toe panel. Disconnect the water line that goes along the front of the unit to the door dispenser. Then pull that line through the by pulling the line from the tank. Then from the back remove the compartment cover and then disconnect the water line from the valve that is the larger of the two lines. The smaller line goes to the ice maker and the larger one goes to the water tank. Once removed from the valve, you can remove the line from the front by the tank and remove it fully. Just be careful to remember which hole the lines go through.
