Default VACUUM lines

just picked up my new to me 1976 vette. I'm going to replace all the vacuum lines car has been sitting since 1985 and all the lines are either having some cracks or are brittle.
Is there any outlet to get them all or do I just go to the auto store and do piece by piece.

or does anyone have a list of which sizes and amounts needed for 350 automatic

There are kits for the headlight vacuum setup, don't know about the rest.

I normally go to the autoparts store and just buy bulk vacuum line. 5/32 & 7/32 usually...

the nice thing about the kits for the headlights is they will have the color coding on them to make future diagnostics easier, but it's not necessary.

There may be a kit for the emissions hoses. Shop around.

When I replaced mine I purchased the entire kit from one of our supporting vendors. They are all cut to length and color coded for ease of installation.

Nobody even comes close to Dr. Rebuild's quality, fit and vacuum system schematics included with his kits.

I got hosed by one of the forum sponsors whose "correct" kit was not.
Check out Dr Rebuild's site to see who has incorrectly copied his kits in the past, and supplied incorrect routing diagrams.

Just be aware...that when you do go and begin to replace vacuum hoses. MANY of the special molded ends the factory made into the vacuum hose assemblies are NOT in the kit. So...if you are wanting to retain the factory molded ends...you are going to have to splice them in cleanly.

Did you remove any parts prior to taking this picture?
Namely the hose that runs from the air cleaner housing to the CAI going over the top of the radiator.
If you didn't remove that flex hose and it's just missing, and if I had that air cleaner\CAI for my 76 (and I wish that I did), I would certainly be replacing that piece of hose to bring the cold air in from the front of the car.

That of course is all just my opinion, some will agree, some will disagree. Either way, great looking car!!

In certain areas of the cars vacuum system;....GM molded the hoses into special sockets or connectors that will easily slide onto whatever they need to go on. These vacuum hose kits generally are NOT made the exact same way as the way GM did it. When you start to get into your vacuum system...such as possibly the charcoal canister or the TVS ( temperature vacuum switch) on the intake manifold....if they are still factory...you will see what I am talking about...and how the emission hose vacuum kit have the correct color hoses...but are NOT molded the exact same way GM did it....which is why it will require spending time joining the two together...if you care about ahve the special molded ends as GM designed.

Good advice. Just be very methodical and deliberate when changing out the hoses. Work on one at a time so you don't get hoses mixed up. Also, when you find a non-standard hose end, check to see what you got in the 'new' kit. If it's not the same, figure out how to scavange the special pieces and reconnect them onto the new hoses.

You will likely need a number of straight unions of different diameters to join hose sections. Also a good idea to use a bit of sealant on those re-connection fittings (but don't plug up the hoses with it!).

thanks for the compliment Nick and I did order that intake hose it was missing.

Just got the name of the original owner and am going to contact him and see if he has any of the original paper work. got the owners manual and tire book and warranty book and stickers that they used when going in for warranty work and a few of the original work orders. just trying to find if he still has the window sticker and anything else.

going to replace one by one even though everything works they just a little hard and a few cracks at the ends (which could be trimmed)

just picked up a compressor actually bought a 1986 Monte Carlo for some parts and it had the right compressor this was a late 1976 vette so it had the pancake comp.

now i can use some of the parts on my other project a 1986 El Camino Choo Choo with only 70,000 miles
