Vacuum line diagrams

Hi,

The only thing I was able to find is below in the pics. Let me know if this helps. If there is something specific you are dealing with, let me know. If I pinpoint a specific component, often times I can find specifics.

I don't know if you are looking for a leak, but here is a link that you may find helpful if that is the case:

Note: Pic 1 is the duratec engine and pic 2 is the zetec.

Let me know.

Take care,
Joe
