I just got my xtool inline fan installed and it's leaking smoke around the fan unit itself.  I've reseated it, changed the rotation to different positions, retightened the clamps, nothing helps.  This is a video of it smoking.  Anyone have any ideas?  There's no real seal between the fan unit and the sides that hold it, just plastic to plastic, so i'm guessing that's the issue.  They didn't include anything in the unit for this.
