They way some of us fix a loose tube is to add 3" packing tape to the key points, one turn or two or as needed before it exits the fuse at both sides, just after it enters the wing and at the tube's ends, this way the tube is making contact with the socket and it is tight all around.
This was done to my Boomerag XL turbine jet's tube, it deduced the play by 80% wich was more than enough, it has been flying with this fix for the Las 10 years with no issues, I have replaced the tape only once in 10 years.
Enjoy, be safe and report back.
Tks.
