I completely removed the HVAC and AIR systems from my 02 C5 Z06 race car.
I think I should be good to remove the vacuum plumbing and canister in the right fender but I want to make sure I am interpreting everything correctly.
Do I have to plug the line that comes from the intake manifold if I remove everything else?

I have attached a picture with my current understanding of the vacuum system:


Vacuum components - 02 C5 Z06

Is this correct or am I missing something?

Thanks in advance for your help!

Yes, if you remove vacuum lines you need to plug the remaining line or opening or else you will have an uncontrolled air flow into the manifold.

So reusing one of the check valves to plug the source from the intake manifold should do the trick. Will give it a try.
Thanks!

Sealing a vacuum line using a check valve? You need to use a small vacuum line cap. You can get a variety pack at any auto store.

Go to the source of the vacuum. Seal the nipple fitting on the back of the intake manifold. Otherwise, you risk the chance of the line cracking or melting and leaking air.

I was wanting to mount my passenger side coils in the spot you have circled but that solenoid is in the way... I assumed it had something to do with the ac so I didn't want to mess with it but I have my air pump removed so if this solenoid goes to that stuff I could move it out of the way... does the vacuum line and wiring go all the way over to the driver side where the air pump is located?... I'm wondering if it would be difficult to remove the whole line and wiring, if it's too much work I might just leave it there and move it out of the way
