Intake Vac Line Questions Need HELP FOR THE AM!
- Thread starter Adam95GT

I think i broke them off... hard lines correct???
Where do all the lines from this mess go to??? im getting rid of smog so what can be removed...
Also what is this red line for???
From noticing that the red line is branched and goes to all the solenoids in that pass side cluster i can only assume that its the vac source for all them and can be put to manifold vac. Not the green one goes to the egr valve... so whats the rest of these lines??? all smog??? and there is a vac line going to the black box with nothing attached.... where does that go to??? You can see it hanging down in the first pic.
Ok so i have also concluded that pink and grey are smog.... so i removed them... still dont know what that thick black one connecting to the black box is.... its on top and has like 2 t's in it...

Ok where does the line from the charcoal canister go... the one on top
Thats this one, but i dont know where the other half of those Ts go??? Also, most of my hard lines from the smog stuff leaked, i capped off the AIR lines, as i elimanted that smog stuff, and i re-did the EGR line with rubber hose, my only good line was the red one, as you see in the pictures
that cant be the line.... i thought that goes to one of the back ports... its not nearly large enough.... if it goes there what goes to the 2 back ports... one goes back to the gas tank
The two up top are connected by a T and have a line connected to them....
then there is the one outter most on the left side.... if the canister purge goes on the top where does that other line go to???

Not my car but the red and blue lines are the ones im talking about....

Blue is for the solenoid..... red is still to be determined.... traced it farther in these pics.... still have no clue... goes down to smog pump area ...

Ive gone threw this on my car and on a friends car last week.
All of those colored lines and electrical plugs are smog related. That whole unit is bolted on with three bolts. You can REMOVE it ALL along with all the vacuum lines that connect to various emissions crap under the hood.
Vacuum lines can connect anywhere on the manifold where they fit. the vacuum tree is basically a glorified T fitting. Connect it to the manifold and everything on the tree will have vacuum.
As for the line that comes from the charcoal canister is the purge line for your evap system. the round thing with a 2 wire plug on it is the purge valve. KEEP IT. Basically what it does is vent gas vapor buildup in your gas tank. The other line just stays open at the frame rail.
Oddly enough removing all that stuff in the passenger fender wont trip a check engine light. But disconnecting the EGR will. If you don't have a chip yet like me you can keep the EGR plugged in (electrical/vacuum) and the computer will play nice even if the egr isnt bolted to the intake

I thought it stayed open i couldnt see it connecting to anything down there
Im keeping EGR however so i need the green line and the red supply line

you don't need any of those Christmas colored lines.(Red and Green) Just connect the egr vacuum directly to the manifold. the egr will still operate as normal (opening at cruising speeds) Only way i would keep all that crap in the fender is if you're keeping your smog pump.
To be clear, he means to connect the feed for the EGR solenoid to manifold vac. If you supply the EGR valve itself with manifold vac, the car will idle like crap or not at all.

Right what he said. 
I know what to do but have the hardest time explaining it...especially typing it. I almost rather drive from RI to NJ to bolt the damn intake on rather than type about it.

iirc the one that your drew out as red, ends right under the frame rail in front of the tire. i could get a pic of it on my car, but it won't be until tonight.
Edit: i might want to add, that it ends, cause it just vents to the outside.
I can't really tell which line it is supposed to be, but I think that's your discharge line. If so, it should go through the fender and connect to the purge solenoid.
