New owners, water tank leak question.

Thanks everyone. Here are two pictures of my water tanks. They are the same materiel as the black and grey tanks. These two pictures are taken from the back looking forward. The one closer in the picture has the leak. It is a cut in the bottom of the tank and it's about a inch long. The second picture shows a tube going into the back tank and some wires going into the front tank. Can anyone tell me what they are for? Do you think it is possible to take the big black pipe off the rear tank and cap it off so no water goes into it and just use the front tank until I can get the tank off and repair or replace it?
