1G List of ALL vacuum hoses, for ALL DSM models, where used, sizes & lengths?

[XC92]

I'm wondering if someone's compiled a list of literally every vacuum hose in the various DSM gens, years, models & variations, in terms of what they do/connect, their sizes/IDs and their approximate lengths? This is for stock setups, not heavily modded ones that have their own specific hose needs.

I know that there are diagrams of all the various hoses available, lists of sizes, and kits you can buy that have every size and length you need. But I'm looking for something that puts it all together in chart form, so people both know what to order for their specific needs, and are able to correctly connect everything.

If such a list doesn't exist then I might compile one myself as I took everything intake and exhaust related off my Talon to overhaul these systems and am about to put it all back on, replacing all the hoses which I'm pretty sure are original and rotting. I have what I think are enough lengths of the various sizes of hoses to replace everything, but a list would help to make sure.

Btw most of the new hoses I got are high heat silicone ones that I got from RTM, but I also got some standard non-silicone ones from RockAuto. Are there situations where silicone is preferable, and vice-versa?

Road Race Engineering used to have a kit called the Larson Hose kit, maybe they still do. That might be a good place to start. I personally bought that kit many years ago and it was right on the money for my 1g.

Thanks but such kits just list all the sizes & lengths of the hoses in it. I want a very specific breakdown of what length hose is used for literally every vacuum connection in every stock DSM made, or as close to it as possible.

I doubt that one exists but it's worth asking, and if none does I'll try to put one together for at least my DSM as a starting point. Such a list is comparable to a list of every fastener type and size used in all the DSMs.

I just noticed that the vacuum chart for a '92 turbo non-California DSM is slightly different from the chart for previous 1G years.

Specifically, the order of hoses connected to the throttle body is reversed.

On '88-'91 models it's Red-Green-Yellow-Black going from rear to front, and on the '92 it's Black-Yellow-Green-Red.

It's not the color that matters, of course, but what each hose is connected to:

Black: Purge Control Valve Side Splitter
Yellow: Thermo Valve Bottom Splitter
Green: Thermo Valve Middle Splitter
Red: Purge Control Valve Bottom Splitter

I don't know enough about all this to know if it ultimately matters, but it's something to be aware of if you're working on these DSM model years.

This is the '88-'91 Chart:

And this is the '92 chart:

I do have a question though.

There appear to be at least three kinds of vacuum splitters. One is a classic T-shape, a second is F-shaped, and a third is H-shaped.

Do these function differently, or are they differently shaped to route hoses better without kinks but are otherwise functionally identical?

E.g. do any have check valves, proportioning valves or some way of unequally dividing the vacuum output say with different sized bores?

I ask not just to know, but because I might want to replace them with new ones and I just want to make sure that I can use conventional T-splitters.
