Thankyou for that link. Yes, I saw it and it explained a lot for me.
I went shopping for the tubing this morning but haven't located any of the soft tubing yet.

BTW the tubing isn't that soft, it is quite firm and it needs to be or it wouldn't stay on..
If you can't get any where you are email me and I'll get some and send it to you.
