Nothing Sucks Like Vacuum (1976 L28 Piping attached)

When you select your vacuum hose, keep in mind whether it is just plain air (like for the he heater controls) in the hose or if it might contain oil or fuel fumes (rocker box or emissions system.) The latter requires an oil-or gas-proof material. Also make sure you get hoses that won't collapse from the vacuum.

Thanks Tomohawk I'll be sure to ask for the right hoses now.
