What vacuum lines do you actually need??? Just wondering what you actually need. I am wanting to keep the engine bay as clean as possible without doing the ls6 pcv conversion.

depends. what are u keeping in the car/ taking out of the car? on my setup all mine out off but the brake booster. my car is all drag so im shaving weigh where ever i can. if you take ur a/c out and climate controls on the inside, i read on here you can get rid of the small one on the back of the intake that goes to the T fitting. and where that line goes is a vac bottle on the passenger front under the wheel well that can go also. hope this helps if your going this route

On mine all that is left is one on the side of the TB PVC lines and the brake. I can get u a pic of the basic idea later today. My motor is just on a stand still togethe so I can set my intake back on it and show u the general idea. It'll probably be after 2 or 3 when I get home and get the pics taken and up on here

ok, heres my set up all nice, neat and ugly as all can be. should be all the same on any intake setup, or at least from stock LS1 to FAST 78mm. im putting 6 pics up. 3 being what it actually looks like and 3 with my "great" microsoft paint skills. (laugh all u want, but fig the more infor the better) and yes my PVC link is gone and thats on my list to fix
here's what it actually looks like
and now the art work
the green lines are the PVC lines with catch can (from ws6store, works awesome), blue is i believe the reall main one you need since it goes to the TB, and the orange goes to a module (see in pic 2) that plugs in a line on the frame by the fuel line (aint got a f-ing clue what it does, may not even need it.
same color code. the piece circled with silver is the rad return. mines blocked off at the TB so its just one long line.
the red circle is where the small vac line in the back plugged. i just capped it off since my HVAC is out.
hopfully this will get you on the right track. works for me

I have a 6.0 and the valve covers are slightly different. On my drivers side rear valve cover there is a hole where you would plug a premade vacuum line in. The passenger side valve cover just has one fitting (the front one). I'll get a pic in a few and show you. I am using an ls6 intake btw.

right, where the driver side line goes its suppose to connect to the other lines but my connector fell apart and and then the passenger side combine together and go to the front to the catch can where the egr valve use to be and then into the intake right behind the TB. should be the same on ur LS6

Ok. I got it. Thanks. I guess I can just get rid of the "t" fitting that you said you were gonna have to replace. I don't have a need for that. Thanks for all the pics. I shall see if it works tomorrow.
