just a quick question on the exact purpose for the vacuum line and what would happen or how the car would act if disconected. I have a bet with a friend and want some of your written results to claim my case of beer hahah thanks all.

Edit: S4 N-A

 

vents fuel vapors and car would run same disconnected

 

its to equalize the pressure in the tank

 

I thought it was for the flux capacitor?

 

Did you win the bet?

 

Yes sirs, He still wouldnt believe me so I had to get up un the car and disconnect it to prove, although I was hoping he would just take your word for it. Either way the beers were cold. I suppose I may owe one or two to the people that replied? If ever anyone is in Ontario hit me up and we can check rides and down a few cold ones .
