I'm not too sure which model you have but it sounds like you have nothing left to do but cap a whole pile of old vaccum lines and then run a new line from manifold vaccum to a tee and from the tee run a line to your pressure sensor and to your fuel pressure regulator and you should be good to go. I guess you don't have to use the tee, you could probably run both to seperate sources of manifold vaccum.

I just did a quick look for you and it seems that it doesn't matter. Every one that i've seen so far including mine has all of the UIM lines capped unless you are using them for something else.
