Are you in a Emissions checked area?

I looked in an online repair manual. Seems they think it's too old to show the diagrams.I do Jeep CJs, same for me, I do have paper Chilton manuals which do show my Jeep's diagrams

You got access to a paper manual. The library is a good place to borrow one.

Sorta what are you doing?

Out of the many lines that came on my Jeep, Only 2 are really necessary (PCV, and vac advance).'Course I have a manual tranny and manual brakes. Still, thats only 2 more!

Can we get you fixed by modifying stuff?

Let's hear the detailed story!
