This is the tank the jet comes with. If you remember, there used to be a Sullivan tank that was available as an option from Boomerang. It did not come with the jet but it was an optional part, and it fit perfectly. I used it in a Sprint and it worked well. This tank is so much better, again another improvement Larry has included as part of this new version. That said, I am not going to be using it as I opted to install a smoke system.
