Injector air bleed
 

Just finished rebuilding and naturally have a few things that i dont know where they go.

There is a vacuum line between the secondary injectors in the LIM this line connects the two injectors and on the end of the rear injector there is another nipple and i have hooked a vacuum line to that but i dont know where its meant to go, i have removed my emissions so i have a lot of xtra vacuum ports, should this injector "air bleed" go to the manifold? or before/after the throttle? or constant vacuum? or positive pressure? and exactly which port? please help.

Thanks and regards

S4?
S5?
NA?
Turbo?

the fuel and oil injector bleeds should go to filtered metered air with no vacume on it,.. on a stock s4 they got to the 3 nipples on the front side of the dynamic chamber.

Specifically, it's the middle one that does not see vacuum.
Also, one of the rear ones does not see vacuum either.

Its for a S5 TII, Which ones dont see vacuum on these manifolds? I know there is a larger nipple on the firewall side that doesnt see vacuum, but its a bit big and i've plugged it. I guess i can pull the cooler off to check which one is which.

Thanks Guys

On the front there are three nipples. The top and bottom ones see vacuum, the middle one doesn't.

On the rear there are four nipples. The bottom sees vacuum, the others don't.

Ok, I'll use the rear ones, so i'll connect the primary and sec. injector air bleeds to the top and third nipple. Because my second from the top is the large port as opposed to the picture here,

is this for a s4 or something? because after reading a few threads noone has mentioned the throttle with 4 ports on the back (that has the large port secong from the top) besides these 2 airbleeds i have capped evrything else.

FPR runs straight (no solenoid) from the angled nipple on the inside UIM, this tees off to my microtech map sensor too.

I hope this is correct, if its not, by the time anyone replies i would have put the car back together and would hate to have to take it apart agian.

Thanks and Regards

Yeah, some of the intake manifold only have 3 fittings in the rear.
Some of them have 4.
I dunno why this is like this. :(
In the rear, the largest out of the 3 or 4 grouped together is for the oil injection splitter.
