I am finding myself in the situation I have previously sworn never to be in: I did not properly mark or otherwise document where the various vacuum lines in the engine goes when I put in a new PCV kit. Thought it would be obvious - but I have at least one line I don't know where to connect - the vacuum line from the fuel rack - where does it go? I would love to see a clear diagram of the engine vacuum lines - do anybody know where to find this?

Thanks

henrik

    From the fuel rail to the vacuum tree next to the throttle body. I removed my SAS and the air cleaner, so that is the only one left on my car.

      Thanks,

      That makes sense now that I look at it.
      Let me recap for you what I have (besides the one you mention):
      One line from the vacuum tree to the air cleaner.
      Another line going from what I think is called the flame trap to
      the opposite end of the intake manifold.

      What confuses me is that I still have a vacuum hose left (not original)
      that I have not replaced. It may have just been behind there and I did not
      notice that it was disconnected when I took the manifold off. If this is
      all I need I will not worry about it.

      Do you really run without an aircleaner? Is yours a turbo?

      Thanks for your help!

      Henrik

        Well, I do have an air filter. I replaced my air cleaner with a turbo version so I could get rid of the warm air intake. So your car will still have a line from the top of the air cleaner to the vacuum tree.

        There is a longer vacuum line from the SAS valve behind the engine to the fan shroud. There is another from the fan to the manifold/vacuum tree, also SAS related.
