i've got a 2000 s4 2.7t. and i'm looking for a vacuum line to install a manual boost controller into. so does anyone know which one a should use? thanks

 

Iblieve you want just a touch over 3mm..

 

that doesnt make any sense. i'm looking for a vacuum line to route a mbc in to

 

hey anyone on here work on their own cars?

 

guess i dont know what your looking for then.. are you looking for what kind of vacuum line or size or what.. Just go to a parts store they have tons of it.

 

I would also like to find out....been thinking of it for my '01 s4.

 

Dont know if this helps for a mbc but Between the Diverter valves is the only real spot you can find rubber line.

 

Ohh.. i get what your asking for..which vacuum line you need to intercept. Well for installing the boost gauge, (which i assume is similar... but not positive as i havent installed a MBC) you splice teh vacuum line that is between the fuel pressure regulator and the intake manifold i believe. Its the only hose thats 3mm hose wrapped in cloth in that area.
