Hi All, I am a new and very proud owner of a 2wd Nissan 720 KC. My Question is does anyone have a vacuum line guide for the Z22 motor, I cannot find one any where. I have checked on the vac line tutorials here and they seem different to my carb set up so i am a bit skeptical about following them. Basically what i want to do is remove all the vac lines and run just one to the advance on the dizzy, the previous owner has done a number on the lines so i currently have no vac advance :(. Any help would be greatly appreciated.

Regardless of the differences in schematics across engine codes, the one thing they share is simply the need for the vac advance to the dizzy. If you don't currently have one, is the hard line missing or welded on the dizzy side? If not, carb baseplate to dizzy and call it good. Remove and cap all others. Hope that helps!
