I have installed a different Hitachi carb on my wagon. It was from a Nissan but came brand new for $35. Anyway, the car runs but I want to get rid of some of the extra vacuum lines. I am handy but not mechanically inclined. I have done the timing belts a couple times and the carb. Ok so what do I need vacuum for? Distributor advance and brakes. What else? Thanks for taking time to answer.

You allso need one for your climate control.

Thanks. This is the one that goes thru the firewall on the passenger side I think. Can anyone think of anything else?

Vacuum you need:

 

1. Distributor, on front of carb above throttle plates

2. EGR, on front of carb, next to dist. barb, but 1mm above

3. Choke pull off, mainfold vacuum

4. Brakes, large line manifold vacuum

5. Climate control, manifold vacuum

 

Then...

 

If you still have the charcoal filter (fuel vapor can) you need one for that

If you have an AAV (drivers side behind strut) you need one for that. Or ditch it, according to GD

If you have the stock air cleaner, temperature vacuum switches, PCV system and associated doo-dads, you'll need to route them according to a manual somewhere. But if you have this stuff, why are you messing with vacuum anyway?
