I can't get my mind around the idea of dunking the tubing in hot while the sapline is already routed and under tension. I tried pushing my tubing (3/16" Leader 30P) onto a fitting with very hot water and no tension and it was very hard to grip the tubing. I could easily do 5/16" tubing, but this was way more difficult.
