Good evening. I am in the final steps of finishing a head gasket replacement and a basic refresher of my C4. The issue is that many of the original vacuum lines have become so brittle that they snapped and I do not know what is what. Can someone take images of you C4 1992 LT-1 base model engine vacuum lines with a description so that I can get replacement hose and fittings?
If you take pictures of the broken lines someone will be able to help.
I will do my best. The issue is that 95% of the lines disintegrated once they were touched so I really am not able to take pictures of the lines as I don’t know what is what. The only line that is recognizable is the solenoid that goes to the right side of the intake. There is a picture of that on the forum already.
sorry I am not very helpful and understand if I am limited on the help that can be given. If a C4 owner with the 92 LT-1 can remove the plastic covers and take a few pictures of the engine from above that would be helpful. I have pictures of the engine but forgot to remove the plastic corvette covers so that part is obscured.
Mine is a 95 but shouldn't be all that different. Here is the passenger side and last one is drivers side: I always run mine with the "plastic covers" off and my vacuum lines have held up pretty well. Hope this helps.

"Doc Rebuild" sells the various years in complete sets with every vacuum hose marked/ or color striped as originally done from the factory. I don't know if your year is on his website but it is worth checking. I had one of his kits installed over 25 years ago now. If you wipe it down it is still beautiful stuff! A quality product!
I have one of their 1968 Corvette Vacuum hose drawing's/"Poster". It is a schematic of the vacuum system. and is mounted on a wall for constant reference. The system is quite complex on the 1968 with a special eye for detail can make it "beautiful". I was proud to open the hood of my Corvette with its 50 plus feet of color stripped vacuum hose in it. The mechanic was very familiar with C3's and installed the whole set very quickly and had all the right parts cut the right length. He was a restoration expert, I was lucky to get him. That experience and all the right lengths of quality hoses marked perfectly made my car look and work great.
I have had the pleasure of meeting good old "Doc Rebuild" Himself at Corvettes@Carlisle.
His kits are things of beauty, the hoses clean, smooth with appropriate color stripe! I have purchased entire Corvette kits which made the system tight and sealed after they were installed decades ago. With the total number of individual hoses on the early 1968 C3 I should probably change these and keep spares as well. I got a lot of attention because the proper hoses went to the proper parts and it look. Every Vacuum hose is replaced in the kit with plenty of length to run the hoses.
The fact is Doc Rebuild makes Great kits as they are more "Complete" and "Correct" than any another!
If you ever need an "Proper" C3 vacuum hose kit he is "The" Man!!
