Sorry... my bad. Should've said vacuum "tree". The "T" for the PCV valve works good just the way it is. Cap the one for the EGR and use the one for the fuel regulator as is. The one going to the firewall, you can use for your brake booster if you have power brakes. (not shown in the picture) is the port on the other side. I used that one for the fuel vapour purge solenoid. My Explorer intake had another port opposite side of the intake under where the "T" is. I cut that off, then tapped it with 3/8' NPT thread and put in a plug.
Hope that's better
