Lubricating system during emissions removal...
 

I have searched this so don't flame me, but I want to ensure that I get this right.

I am removing the remainder of my rat's nest, but I know my fuel pressure regulator and my pressure sensor must still see boost from the nipple on the passenger sides UIM.

If I intend on keeping the oil injectors (whatever you call them...), should they still see the nipple on the back of the UIM?

the oil injectors should have functioning air bleeds but the connection is not the back of the intake, but rather between the throttle body and the AFM on the intake.

Well that's what I meant with saying back of the UIM, but I assume these must remain hooked up to the vacuum nipple?

Yep, but the FPR should be fed from the angled nipple on the inside of the LIM.

Correct, as should the fuel injector air bleeds. :)

The air bleed nipples are on the back of the UIM, after the TB spacer, not on it. ;)

Hmmm... the oil injector air bleeds are not hooked up to the back of the UIM on the S5 models, but rather between the throttle body and the AFM

Unless we are talking about some other thing

I'm talking Turbos, I guess you're talking about NA's?
