in what places the the vaccum lines go on the back of the upper intake manifold,i know all 3 on the front get capped,and i know the big one on the back goes to the oil injectors...please help asap thanks

 

I'm not too sure which model you have but it sounds like you have nothing left to do but cap a whole pile of old vaccum lines and then run a new line from manifold vaccum to a tee and from the tee run a line to your pressure sensor and to your fuel pressure regulator and you should be good to go. I guess you don't have to use the tee, you could probably run both to seperate sources of manifold vaccum.

 

yes its just wierd in the manual it say the fuel pressure regulator line goes to the nipple down by the injectors but its not???? i just need to find out where 1-4 on the back of the upper intake manifold go 1 being the top one 4 being the bottom...thanks

 

is your car and S4 or S5 and is in an NA or Turbo, they'll be a bit different...

 

I just did a quick look for you and it seems that it doesn't matter. Every one that i've seen so far including mine has all of the UIM lines capped unless you are using them for something else.
