Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
None of the diagrams I've seen answer my question. I have an 87 Camaro 2.8L mpfi the double vacuum port on rear of upper plenum I know the large side goes to the brake booster I have a hose from the vacuum cannister in left front fender and a small very short plastic line from firewall at the a/c heaterbox area. I need to know what type of connector marries the saller port on the plenum to these other two lines that I think are for the heater controls. The car was disassembled when I bought it.
If you found the diagram for your 1987 2.8L, with the vacuum can in the front left fender, may I have a copy? Thank you. Brett

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
THANK YOU!
Might you also have the vacuum diagram for the HVAC vacuum hoses for a 1987, 2.8L, MPFI? My Camaro has the vacuum accumulator ball under left front fender. The P.O. removed the vacuum hoses for the accumulator ball, the heater valve, and the thru firewall hoses too.
Again, thank you,
Brett

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
All of that is not part of the vac diag unfortunately. The diag covers the "engine" only, but the accumulator and all that, is part of the "car" and varies according to what options are installed.
However, it's pretty simple, and doesn't depend on what year (up to a point) the car is or what engine it has. There will be a line coming off of a vac source on the plenum or intake manifold; it will go to a check valve, pointed in the direction that allows vac to suck through it, but would prevent "blowing" in the direction of from the vac source toward the rest of the world; there will be a T fitting (some check valves incorporate the T); one leg of the T goes toward the HVAC control head (the purple small plastic vac line through the firewall) and the cruise, the other goes toward the Orb Of Power in the fender. The purpose of it all is to allow vac through the check valve when the vac is hogh (idle & cruise), then when the engine vac falls (hard acceleration), the Orb holds enough vac to keep the little doors under the dash that direct air from relaxing, and the check valve prevents the stored vac from simply being drained off into the engine. The white little plastic line through the firewall goes to the heater control valve, if your car has that.

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
I have a 1982 Trans Am Recaro that I have owned since new. It has a Standard shift 4 speed and carburetor. Do you have a vacuum line diagram for it. I have only found the one you posted for the automatic with carburetor. Thanks, Dan

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
Well, I guess I'll add the 3.8L turbo vacuum diagram so the OP is not lying.

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
Most likely not , this forum is exclusively for the 1982 through 1992 F bodies (The third generation of the Camaro/Firebird , hence the name "Third Gen . Org") , your best bet will be with a first gen F body forum . It's not like the info is here and no one is giving it to you , It's just that most of us only have info stored for the third gen cars .

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
Raoul,
That hose is part of the "car", as opposed to the "engine"; therefore is not part of the "engine" vac diagrams.
It serves the HVAC and cruise control (if equipped).

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
Can anyone help, I need a vacuum line diagram,
Where can I get a diagram for hooking up the vacuum hoses for a 1985 GMC S15 with a 2.8 L. automatic. It has a V6 4x4.
Also does anyone know where the line goes from the manifold outlet right behind the Carburator

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
To paraphrase a somewhat-famous fictional prison warden, what we have here is a failure to communicate.
When OP stated that he has "ALL vacuum lines from 82 - 92 TG F-Bodies!!!!," that's what he meant----only Camaros and Firebirds build between the years 1982 to 1992. No 4x4s, Toyotees, Hondoos, mid-sized pickup trucks, Mopars, 2015 Cazadors (WTH is a Cazador???), Fjords, skateboards, buckboards, or floorboards.
So, for all you non-3rd-gen vehicle owners searching for vacuum line diagrams, The Google may be able to direct you to a more-appropriate interwebz forum.
Good luck and take care.

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
I'm in need of the vacuum line diagram for the digital HVAC climate control for an 88 GTA doing a conversion and I'm going about it a little bit differently and so far so good I just have come across a few images where it showed an extra vacuum line coming through the firewall and I just wanted to make sure I had the right count and positioning

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!
okay that's kind of what I was figuring and that pretty much confirms it for me I thank you for that, I guess the next question I would have is if I wasn't going to install a heater diverter valve and was just going to utilize the vacuum Supply from the engine to the HVAC system which of the two taps on the plug would I want to use the one that goes to the purple line or the one there goes to the gray? See I would think most of the stuff should be obvious just looking at it but I thought that in the past and they've been proven severely wrong and mistakes were made. Thanks again in advance
