Hi!
I need to test the vacuum lines, has anyone built an effective and easy smoke test machine?
Thanks for the tips!

Made a variant of this a while ago. Used the tiny cooling fan from behind a dailed led headlight instead of a manual pump. Might be able to get creative with a vape device. Find it more effective though to just individually test every hose or component with a hand vacuum pump. You get the bonus of knowing whether its time to replace the hose if it falls apart or comes off too easily when removing it. Also result is not as susceptible to variation in temp. Careful with the aging hard plastic line though.
