OK so i am sure this has been covered before but i still am lost on my vacuum setup.Sorry for such a noob question but i'd rather be safe then sorry. For starters i have a 90 Crx with a b18a1 in it. It has a AEM Fuel pressure reg on it which is one of my few concerns, it has a lame original b18a1 intake mani with all sorts of air boost valves and egr crap, i used to have a single cam turbo that had a obd1 tb so we deleted the Charcoal canister along with the firewall map unit and ran the map on the tb and now that i am back to a obd0 tb i am not sure how to run the vacuum lines to the external map or anything pretty much ha.
