I may have it in my 1990 GM shop manual. I'll get back to you tomorrow with an answer. If I do find it (which I will), I'll pm you with a new thread. Don't wanna stray away from the main vac. line topic.

Okay bro. I am more than willing to help you out. But there are about 25 different diagrams man. If your on a pc, right click the opropriate picture, copy it, then paste it in a new post below. Then I'll know which vacuum line your troubleshooting.

It's a 2.8 Camaro big dawwg! Duno how to post pic but it's at beginning of this thread

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.

Well the best way to know what and how to connect the lines is by posting on the general engines threads. Copy the vacuum line picture and make a post with your question. Then when someone with the same engine sees your question, they may help you out. You gotta remember that I posted these pictures to help out the community. I only have a 86 IROC, TPI. So I don't know every other engine by heart other than mine. Please do use the diagrams as guides.

There may be a splitter or a check valve. I'm not sure but that's the best answer I can give. Perhaps you can copy the diagram that best suits your engine and make a tread under the general engine thread.

Did you search the first page of the thread? Should be there.

I have a 82 z28 with 4 barrel carb 5.7L engine and TH350 trans ignition is electronic not vacuum advance it also has smog setup I sure would like to have diagrams for the emission and smog lines. Thanks for any help you can give.

iTrader: (17)

Is that factory?

porkbuttman2204

I think it is.

Chevy86 IROC-Z

iTrader: (17)

I don't think it is unless someone else proves me otherwise. All combinations that are listed are from a good source. If you can trace back the PO, maby they can shed some light. Other than that, your best bet would be to look at a similar set up that closely resembles your set up on page 1.

Good day gentlemen, is there somebody out here who have a vacuum diagram for a Toyota 2E?

Chevy86 IROC-Z

iTrader: (17)

Try a Toyota forum. Notice that all the diagrams I provided are for Camaro's.

m1911a2

yes sir i do notice but because of my desperation, am taking my chances that somebody out here might know about my need.

Chevy86 IROC-Z

Sorry man. I only have service manuals that display Camaro stuff from 82-92.

Lastly Sir, are you familiar of Aisan carburetor?

Sorry man. I have never heard of that carb.

Hey man, hate to bring up a dead thread, but could you hook me up with a few of these? My car's kind of a hackjob from the previous owner. Could you hook me up with vacuum diagrams for an '89 5.7 TPI, '90 5.7 TPI, and an '89 TBI?

Before I get anymore requests about a diagram, go to page 1 and

The 82 5.0L Carb diagram is WRONG. I would follow the 83 diagram for an 82 as 82s came with a VAC Sensor and do not have any vacuum sources on the distributor. Also the vacuum line to the Air Cleaner is not on the back of the carb, rather should be like the 83 on port B in front. The VAC Sensor should be connected in back with the hard plastic tube.

thanks i have been looking for this for my 86 305 carbureted iroc. just one thing thou my 86 air filter only has one snorkel on it. is this right?

Chevy86 IROC-Z

Ok "KnightmareCS". Take your concerns to GM, which is where I got these diagrams. Have a GOOD DAY.

Chevy86 IROC-Z

iTrader: (17)

Good question man. I have no idea.

iTrader: (7)

Sorry, my frustrations weren't toward you. It was to the incorrect diagrams for 82.
These are the same diagrams seen in ALLDATA, Autozone, Chiltons, etc.
Unless, of course, they're for some weird California/Canada cars. Anyways, can't seem to find one for a regular ol 5.0.
