Thread: Identify vacuum lines etc...

I am trying to repair a 99gtp that had an engine fire. On my intro thread(http://www.grandprixforums.net/f77/intro-6388.html), someone posted a link to a picture that I have modified (http://www.spitzeperformance.com/Pictures/Engine.jpg). It has three objects circled (labeled 1,2, & 3), as well as three vacuum lines (labeled A, B, & C). Can anyone help me identify the names for objects 1,2, &3, and the destination of the vacuum lines labeled A, B, & C? Thanks very much in advance!

the vacuum line should run from the boost bypass valve to the fuel pressure regulator to the nipple on the lower intake manifold to the MAP. makes a loop around the blower from front to back around the snout side.
