I ordered the silcone tube from Mcmaster, if I don't like it the Dealer and get the part number you listed in a day or two for 3.21. I did see one person ask the question about the tubing saying "not rated for vacuum" does anybody have any problems with this stuff?
From what I've read (on here) the hose is 5.5mm and 3mm. Those seem hard to find. I see a lot of 5mm and 6mm all over the place (Amazon and such) but not much 5.5mm. However, I did a quick search for 5.5mm vacuum hose on google and saw this:
the 3mm you can get from mcmaster.com for about $1 per foot. Mcmaster also has a 6mm, but not a 5 or 5.5mm ID. The 6mm might work OK. I don't remember what I used, but I did mine about 10 years ago and their selection may have changed.
