I de-smogged mine when I installed the TFI, it makes life much easier when "under the hood" IMO. Pull all related hoses/pumps/crap and replace with high quality automotive rubber caps where needed.
I did this too, same procedure. I used those rubber caps and zip-tied them to make sure they didn't slip off.
