Heres the deal, I have a 88 Iroc 350 TPI with a vacuum leak somewhere reaking havoc on my ride, I bought the car right after a friend of mine swap a new motor in it and he didnt know what he was doing and has the vacuum lines rigged up with bolts and tape and all sorts of nonsense. So another friend of mine said he will just run new vacuum lines and that will fix the problem and told me to just go pick up the material I need.

My questions are:

What exactly do I need and how much of it do I actually need?

Are vacuum lines for a thirdgen something that I can buy from Autozone, Advanced Auto Parts etc......

Is it something I have to buy from like jegs or summit and if so does anybody know the part number?

Please guys give me some input, so I can get my iroc fixed and enjoy my summer cruising with my t-tops off.

There should be a vaccum diagram on the underside of your hood. I replaced my hoses. I bought 10ft and still had a little left.(Just for the engine compartment). God Bless US All...John

Yea I have a aftermarket hood so that diagram is long gone, where did you get your hoses from?, and what kind of hoses where they exactly?.... Sorry for my clueliness I really know nothing about under the hood.......

I used a hose candy kit i got from jegs. It was a little pricey, but they work well and look good. Also they are silicone so they will last a long time.

Take one of the old hoses with you to the parts store, and say I need x amout of length of this vacuum line. You don't need anything special for vacuum line. If I have left overs, I just throw it in my hose drawer in the garage. I can't count how many times, i've needed a length of line on a saturday or sunday night when no one was open.

I have replaced vac lines with rubber vacuum line. I didn't look at any diagram, I just traced the old ones and replaced them one at a time. Tedious, but It works.

It is a little pricey but if it comes with everything I need to get this leak fixed I dont mind paying for it!!

Did this kit come with everything you needed to replace your lines or did you have to buy anything extra or use anything extra???

Thats what I was thinking maybe I should try to do before I pay my friend to do the work just to save a few bucks, but if it looks hard then Im going to have to chuck over the money, like I said when it comes to under the hood Im clueless lol.....

I was looking around and found where someone had posted all the vaccum diagrams. I typed in heater in the search box and after a few pages I found it. If I can find it again I will copy a link.
The hoses are not hard to change. God Bless US All...John

That would be Great!

thw vacuum diagrams are here. https://www.thirdgen.org/forums/tech...iagrams-i.html

As long as you have all the old vaccuum fittings, then it should be straight forward. Just use the old hoses as a template for your cuts. You should have plenty left over in case you feel like changing the routing at a later date.

I replaced mine on my car with windshield washer rubber hose. Match it up close enough and save some of the old vacuum lines so you can use those for the connections with no problems and use the rubber and connect it to the hard plastic. Zip tie them together. Driving for around 500 miles of pure beating on it and had no problems. Should be good

Why not buy vacuum hose?

Because they had to order hard plastic lines. It's the same thing. It says windshield washer tubing/ vacuum line on the box

Alright, then it is the same stuff as I use. I prefer it to hard plastic.

Ok advance has a really good online sale going on now and I'm trying to pad my order.

Anybody know the inner/outer diameter of the tubing in our car? I'm talking about the slightly larger rubber ones, not the thinner ones with the elbows.

If you take a piece of the hard plastic line to the auto parts store, you can match it up to the right size rubber one.

Chevy86 has all the diagrams for the cars. You just need to let him know the year and he will share the info. Good luck!

It's a 92....

I've already ordered though... as I said, it's an online sale. I was afraid it would expire soon and if you order more than 75 dollars worth of stuff it's essentially 40% off!

I got a couple of 5/8 inch hoses.... from what I could tell online it's used on some part of my car at least, so it won't be a waste. My car has been sitting a little too long so I'm replacing ALL of the vacuum lines anyway.

Advance doesn't carry a lot of parts for camaros but it's a good sale! For 48 bucks I got two rear hatch lifts, two rolls of vacuum tubing and some of those self-adhesive metal patches to aid in filling rust holes! The catch is in order to get any actual savings you need to use local pickup... but I actually prefer that anyway.

So my suggestion is, if any of your lift supports are bad buy em there before the sale goes off. And yes, these have a (limited) lifetime warranty as well.

Hey guys so I decided to run the lines myself, its actually a lot easier then I thought, well I ran into a problem I noticed that the EGR Solenoid seems to be missing from under the hood.... Is there a way to run the lines with out the solenoid or is it a must have part in this equation when running new lines in our third gen?

Also is there a certain type of fitting i should be using?

any input about the egr solenoid??
