Vacuum Lines Diagram

[admin_JAinsworth]

Ok guys, here it is, the be-all...end-all vacuum line removal thread, enjoy 
The list of ports (22 in all)
 
1. Vacuum Retard Diaphram (directly on top of the distributor)
2. Top Port on the TB, right where the OVCP meets the TB
3. Secondary Air Cleaner Assembly (black box on the drivers side of the VC)
4. Thermo Valve (2 ports)
5. EGR (3 ports)
6. SACA Solenoids (5 ports)
7. Main Vacuum source (3 ports)
8. Bottom port, this feeds the vac storage, cruise, and runs to the vac pump in front
9. Vacuum Storage (not pictured), mounted to the side of the shock tower
10. Cruise Control (not pictured), mounted to the front of the shock tower
11. Vacuum pump (not pictured), mounted right beside the drivers headlight  
12. Purge Control Valve (2 ports), directly under the aircan
 
Now, depending on what you're wanting to do with your car, your position on the environment, and whether or not you need a smog test to get a state inspection, it's possible to remove some of the vacuum lines and clean up the engine bay a LOT.
 
For a pure race car you'd probably just need 1 stock line (slightly relocated), that'd be a line running from the top of the TB (labeled #2), to the Vacuum Retard Diaphram (labeled #1), this is the only line that is an absolute necessity.  However, if you want, for example, your inside head & foot vents to work properly, you'll need to keep the line running from the bottom of the TB (labeled #8 ) going to the Vacuum Storage canister (labeled #9) (+ the single, small vacuum line running from it's nearest "T" into the firewall [not pictured or labeled]).
 
Since this comes up frequently I'll address it here, the vac port you use for a BOV is labeled Main Vacuum Source (#7), you'll use the one closest to the firewall if you're looking at it from the drivers side fender.
 
If you need a smog test to pass a state inspection you'll probably need to keep everything, each vacuum assisted item has its place.
 
If you've removed the catalytic converters you won't be needing the Secondary Air Cleaner Assembly (labeled #3), it supplies fresh air to the catalysts.
