So I figure finally got my new vacuum lines and intake sensor and I'm about to replace them all. I got a diagram on how to do the lines elsewhere on the forum. The weird thing is that as they are in my car they aren't set up anything like I the diagram. Should I tear them all out and set it up as close to the diagram as possible or replace them as they are?
