Re: New Vacuum Diagram
If you have one for a 86/87 TPI that would be great. It's an 86 car but with an 87 engine, 5.7L V8 TPI
Thanks,

Re: New Vacuum Diagram
I'm working on what I believe is an '88 5.7 TPI setup. I only see 2 vacuum ports on the throttle body. the small one on the bottom and one large on e on the side that goes to the passenger side valve cover. any one have a pic of where the other line connects that is shown?

Re: New Vacuum Diagram
if your talking about the HVAC And CC hoses they may have a T and share the same source like my car does.
If people that have these motors that are hooked up correctly will let me know i will add that info. Kinda hard to be shure when i dont have one of each of these motors myself LOL.

Re: New Vacuum Diagram
Here's one for some year of L69; I forget which one. Not that it matters since they're all the same AFAIK. And, the LG4s are all just like this too, except for teh air cleaner details.

Re: New Vacuum Diagram
No; those are accessories, parts of whole other systems (A/C & cruise), not part of the engine. That's a copy of the emissions label, which is independent of what options the car was equipped with.
They get fed from a fitting on the top of the intake behind the carb.

Re: New Vacuum Diagram
What do you need for an 84 Carb? I've got a 84 T/A that's carbed. Let me know what your looking for and I'll try and help. Sorry, I don't have an accurate diagram for the accessories, just going off memory. The Camaro and T/A set up should be almost identical.
----------
That's going to depend on the line you need. There should be about 4 different sizes depending on the accessory or engine part that it's going to.

Another one that is quite hard to find is the diagram for 85 MPFI. It is a one off year.

Re: New Vacuum Diagram
Same as any other L03....
The cruise and AC are part of the car, not the engine. Kind of like, your house builder might have given you a wiring diagram of your house; you won't however, find the schematic of the toaster in your kitchen, on the schematic the builder gave you. The toaster is a separate system from the house, even though it gets its power from the house wiring. Engine vacuum diagrams are usually like that: they tell you about the ENGINE, but then, you need a SEPARATE diagram for any accessory sub-systems that happen to hook up to the engine and use vacuum as one of their power sources.

Post one. Contribute, instead of complaining in all-caps that no one else has done what you want for you.

Re: New Vacuum Diagram
Hi, this is great.
I am currently putting my 91 L98 t/a back together, and cant figure out what connecter? plugs into the back of the egr solenoid. it looks like a vacuum line would connect to it.

Re: New Vacuum Diagram
It would be nice if the diagrams included the alpha codes, like this 1984 carbed 305:
So that owners could positively identify their diagrams.
This is another diagram for a 1984 carbed 305, but there are significant differences:
