where does one buy this stuff. If it's industrial stuff, I can probably get it but need a maker and maybe a p/n. I need some stuff in 3" size. And maybe I can arrange to supply it if there's enough interest.

 

its just silicone hose... the big stuff can probably be had from a auto supply co... (i.e. I'll look around at work in the catalogs on friday/sat)... also try a truck supply company.. someone who supplies parts for the repair of big diesels ... btw.. you'll learn when you see the article I'm sending you that you can source parts from some weird places
