If you give me a day I will check out in the garage and measure my old vacuum hose. Outside diameter and measure what I replaced it with. Here is a link to a company I have bought from before. .94 cents a foot for black 3.5mm vacuum hose platinum cured. So you could get 30 foot if your heart so desires and pay $30 +shipping over that $75 dollar kit. Buying it buy the foot you can just cut it up yourself and even add an inch or so so they aren't so tight. I don't think I bought there vacuum hose but might have. I know I bought stainless steel exhaust rod hangers and I think ss band clamp exhaust clamps. Many years ago. They use to sell on ebay and may still have a store there but would have to look. I know several years ago they sold on amazon too.
