You need to think of the Intruder as a dump truck. All types of bombs, and tank combinations were carried depending on what the mission was.
I would suggest looking for aftermarket tanks like the one you have. Normal tanking mission would be four tanks on the wing pylons and the back up refueling pod on the center line pylon.
Some KA-6Ds were a bit more colorful than line birds so it might be worth reconsidering.
