Just an FYI. If you are using a pump and decide to go with unreinforced silicon tubing, make sure you get something that has a wall thickness greater than 1/16 of an inch (which is what the tubing you reference above has.) The vacuum created by the pump, even when unobstructed, will easily collapse the sidewalls of the tubing, especially when pumping hot liquids. It works great on gravity systems, but the pump is too much for it.
In fact, I have about 40' of unused 3/8 ID platinum cured silicon tubing to get rid of due to this very issue. Got a pump and found that the 10 feet I've been using won't work due to the lack of strength in the walls.
Just my $.02. Hope its helpful.
