Every vacuum line diagram that I've seen for a SD TPI setup has only shown the vacuum lines for emissions equipment, which I'm not using.
Knowing this, what exactly do I need vacuum lines running to? Obviously the brakes/MAP sensor, but I'm not sure what else (If anything else). On top of that, I'm not completely sure which ports on the plenum I should use, and which I can block off.
Here's some pics for reference. Feel free to fill in the blanks for me:

Pic 1:
Red is the FPR to the plenum. This the right connection?
Blue=?
Green=?
I'm assuming one of these is for the MAP sensor


Pic 2:
Where should this run? (PCV)

Pic 3:
Green: Coolant line? (Which I'm going to bypass)
Blue:?
Yellow:?


Pic 4:
Red: Other coolant line?


Pic 5:
Vacuum line for brakes, which I think plugs into the port in pic 6?

Pic 6:
Vacuum port for brakes?


Am I missing anything else?

 

First pic is correct. Red goes to the FPR, the Green one goes directly to the MAP
Blue goes to a 2 way check valve, then from there one to the HVAC system, then the other goes around the back of the motor along the side of the fender and then splits to the cruise control and then to the vacume ball located in the inner fenderwell on the driver side front

Pic 2, the PVC should accually be setup on the other valve cover with the hose running though the runners to the port between the middle runners on the base.

Pic 3 Yellow is NOT a vacume line, but a fresh air line. You can eather leave open and run a breather on the pass side valve cover or run a hose from the passenger side valve cover to that port.
Blue is vacume to the charcoal canister and green is coolant

Pic 4 is coolant as well

Pic 5 should go to pic 6.

There another vacume port located under the TB that needs to be plugged if not using EGR

 

Awesome, thanks for the help!

I didn't see the port under the throttle body; I'll have to look again.

I also didn't see the port for the pcv on the intake. So it seems like it's on the driver's side? (I'm using a vortec intake if that matters at all)

I've currently got the other spot on the pass valve cover capped off. So I should either buy a breather with a filter for it, or run a hose from the fresh air line to it?

Sorry if these are dumb questions, but I'm still learning

 

There is a port next to the 3rd injector back on the driver side for the PVC. The correct way to run it would be the PVC on the first hole on the driver side then with the oil fill plug behind. Other side would have a breather with the top port of the TB capped if you want. Its not a vacume line. Or the factory way of having an elbow with a nipple coming off of it coming fro the valvecover with a hose form that to that top port..

 

This the port in the intake you're talking about?

There's a threaded hole to the right of the runner.



And here's what I have currently on my valve covers (Ignore the non-matching cap)





So I'd swap the PCV valve for the oil filler cap on the driver's side, and then run a breather on the rear pass side, and the oil filler cap on the front pass side?

 

Yes.. Remove breather on driver side and put on pass side. Put PVC on the driver side and connect to that port which doesnt have a nipple on it yet. That hole is a major vacume port

 

Cool, thanks for holding my hand on this one, haha


Final question (And anybody else can chime in on this one as well, give Mkos1980 a break):

What sizes are all the various vacuum ports? I'd like to make it a one trip deal to the parts store when I'm buying lines/caps.


I searched, but didn't find an answer to this.
