Ok, so I swapped out the LS1 intake for a BBK SSI one and while the manifold was off I went ahead and yanked out all the air/egr stuff. My question is what I do with the vacuum lines in the back of the intake. I am keeping the LS1 coolant lines and pcv setup since they do not interfere with the BBK intake so I basically need to know where everything hooks up with my setup. I know that the big hose on the back of the intake on the driver side goes to the brake booster but I am a bit unsure about the little one on the passenger side. There was a check valve along with some other stuff that I think is the egr solenoid but I’m not certain. Correct me if I am wrong but from my interpretation the small line on the passenger side controls the HVAC. With this said can I simply connect this line to the little port on the back of the intake and be done with it or do I need to keep the check valve and other stuff in between it and plug to unused lines? Here are some pics of what I’m talking about.

Here is the thing I think is the egr solenoid. Can I trash this?


Here is the line I want to hook straight to the back of the intake. Can I do this?

Plug it. It was for the air system. Don't need it now

is it not used for hvac? if I plug the line I would need to plug the intake port as well correct? with eveything out of there if i plug that line then there is nothing to plung into the pass side port on the back of the intake.

I'm not sure what the vacuum pieces are you pulled off, but there's no vacuum ports on the EGR.

i figured it out. i was mistaken and it was the air stuff not egr. you can run a direct line from the back of the intake to the pass side hvac vacuum.
