I am trying to locate a tank to put on my spirit proton pack but having no luck finding one. I saw a picture online from a fan who did it but there is no contact information. Can anyone point me in the right direction to a tank.

Most people just make them. Certain bottles have a shape which is pretty close.

You might be able to find a metal water bottle which corresponds roughly to the size you'd need.
