It's a yellow Icon. I removed the tank. Once I removed the tank, I removed the 6 black rubbery circle pieces that go into holes of the tank. The two big ones go near the bottom of the tank, the 4 small ones go in the front 4 small holes near the front of the tank. All I have left are these 4 silver pieces but I don't think they fit where the fronnt 4 rubbery black pieces go. I tried. And the guy that painted my tank doesn't remember either :/Which model is yours? I don't remember seeing anything like that on my FT.
