Im currently working on an Evolution 9 that has a substancial amount of work being done to it. I will be re-routing all vacuum lines and there are multiple different sizes. The car is put through a harsh environment (Wyoming dirt roads and extreme temperature changes). I was thinking of buying a spool of vacuum line for every size I need rather than buying small over priced sections from a Auto Parts store. I am leaning towards silicone black line to resist breakdown from the environment the car is subjected to.

Where are you guys buying your vacuum or silicone line from in bulk?

 

How many cars you plan on outfitting? A few feet of each size isn’t that expensive ($1 or less a foot?) And as luck would have it, usually available at any auto parts store

 

Well, not a lot. But I hate having to make part runs in the middle of working on a car! Dont you?! haha
