Hi Again
As long as the tubing clears the slots in the paper tray and the rollers turn freely, it will work. When I tried using 3/16" braided neoprene fuel line for this application, the outside diameter was slightly larger and the rollers would not clear the slots in the paper tray, so it wouldn't work.
The braided fuel line would clear the slots in the paper tray when I first checked it for size, but once pressed onto the metal core, it would not. The fuel line was a snug fit onto the core, and sliding it over the core expanded just enough for it not to work. Hope this makes sense,

We humans go through many computers in our lives, but in their lives, typewriters go through many of us.
In that way, they’re like violins, like ancestral swords. So I use mine with honor and treat them with respect.
I try to leave them in better condition than I met them. I am not their first user, nor will I be their last.
