4 Vacuum Line Routing The vacuum line routing is described for each major component that remains after desmogging. Each major component is described in its own section, and each section refers to the ports and labels that were given in the section above. This means that if two components are connected together by a vacuum line then you'll see that line mentioned in both sections. This seemed like the best way to describe things so that it was easy to verify that each individual component has the lines routed properly. NOTE: There are several places in this section where the text "unchanged from stock" is used to note that the routing is the same as the stock routing.
I put this in places where I was sure (or pretty sure) it was true. There are probably cases where the routing is stock but the note is missing.
