Me and my dad are about finished with the rebuild of my 85 gt. were trying to completely remove the smog system, which of course has vacuum lines running everywhere. After hours of searching this forum and the internets, ive decided to just ask. What vacuum lines are required to run? figured this would be easier than asking which ones need to be removed. Thanks!

 

Cars don't require vac lines to run. The engine produces vacuum. With that knowledge on you side, you only have to connect vac lines to the items that need vac to function properly. For example, the Brake booster, interior air vents... etc etc etc.

 

So armed with that knowledge, after i find accessories that need the vacuum i could just cap everything else and come out good correct?

Thanks for the help!

 

Why would you cap accessories, when the vacuum is produced at the engine?

 

Sorry i meant cap all the other ports on the intake and carb and what not
