No special tool is needed for the ear clamps, pretty much any kind of pliers will work just fine. Hell a rock and a screwdriver could probably be used in a pinch.

probably because I was using their in-house search function.

Tubing (filter by "Teflon" which covers all teflon materials, then filter by ID and wall thickness)

dudeman thanks for finding the correct tube and clamp sizes. I was too lazy ;)

Yep no problem

holy shit you bought a "tool"??? Lol, I just used slip joint pliers, it's my fav tool to use, and it worked just fine.

Wow, i didnt even know there was a "tool". :)

I went to the tractor store and bought weedwacker fuel line for like 1.50 or so, then used thick aircraft fastening wire and twisted it on to hold it.

That was 2 trouble free years ago.
