Delete part of torus?

[mikeoui]

Attached a photo. So I have a tube with a torus through it, but I need the interior of the tube clear. The torus is acting as a surface accent on the outside of the tube.I've tried flattening, moving, and resizing but that doesn't work. They either don't work at all or they affect the outside part of the torus too. It's fine if I can't "delete" but I at least need the interior part of the torus resized and shaped so it fits inside the wall of the tube.
