97 F150 4.2 IRM vacuum line pic request
 

hello. just asking if someone can post a pic of the vacuum line(s) that control the intake manifold runner valve and where they attach to the manifold...i've read that they may become bad, and i'm throwing an error code of p1537. i checked, but not sure which vacuum lines i should be concerned with, or if i'm even looking in the right area of the engine bay.

thanks in advance. :)
