vacume sources.......?

ok, i think this should be in the FAQ...but which nipples on the mani provide full manifold pressure and which dont...i no some of them are restricted and others arnt (when i got the car the boost gauge only read 4 psi then after removing rats nest hooked it up elsewhere and what do u know full 8psi reading!! lol). im trying to clean my engine bay up a little so instead of t-ing everything off one nipple id like to use closer sources of vacume so i dont have lines running everywhere!!!

thanx for the help!!

The three on the front of the throttle body are vacuum. The lowest one on the back is vacuum.

Then you have the nipple on the right side of the intake manifold for the BOV and the one on the ACV that is vacuum. IF you removed the ACV, then the blockoff plate you bought/made should have at least three nipples on it to use. If they didn't install three nipples on it, get your money back. Done.
