Look on the bottom of the hood for the emissions label.

Are you referring to the vacuum lines on the back of the intake? If so here is a good shot of that.

 

The red label "goes to vacuum reservoir" is not clear; where is the vacuum reservoir? I believe it should be labeled "fuel pressure regulator" as this looks to be M52TU intake.

 

Year and model? M52 or M54 or M56?
