Help with vacuum line spaghetti

[SilveradoDude]

Just wanted to piggy back on this post. I also have an '85 with a 305 Quadrajet and I want to do the same thing.
Would the diagram that you provided work for my truck?

My specs
- I have the UHK vacuum setup
- Don't use cruise control
- I haven't removed air pump yet
- I am assuming with the EGR and EFE valves I just leave them where they are and plug those up
- plug the unused ports on the carb
- removed A/C
- Also not running Electronic Ignition Control and using 84 distributor

I'd like to remove the following:
- EGR valve
- Decel valve
- Delay valve
- Diverter valve


What is the bowl vent in your diagram?

Okay UHJ = 5.0, federal emissions (not CA), AT and not high altitude:

Here is the original vacuum routing diagram - same as on your radiator support:

You didn't respond to the EGR or Thermac questions. So I'll just guess and go with EGR delete and keep the Thermac functional - and just do the best that I can.

This is what you should end up with when you're done stripping all the unused tubing, vacuum switches and delay valves;

With the vacuum routing as shown above, you will retain full functionality of the EES (evaporative emissions system), ESC and the Thermac system - along with vacuum advance for the distributor and a vacuum supply for the cruise control and HVAC control. And your engine will look a lot cleaner.
