Called by him a "connector." Known in the trade as a "bulkhead fitting" (used to pass a tube or pipe through a bulkhead.)
I was not pleased with my vacuum wiper retrofit on my 29CC pickup truck. Driving with vacuum wipers is NOT the modern experience of driving with electric wipers. You accelerate and the wipers stop - which is like the worst possible thing to occur at the worst possible time. And modern speeds on the road require greater acceleration and throttle position - both of which reduce vacuum available to the wiper - and reduce their speed and reliability.
The truck was originally hand wiper only - so I had license to put anything I wanted in it's place. A JC Whitney 6v wiper motor for $9.95 (then) did the trick for me.
But you do what pleases you best.

Mitch: Has been discussed on the EV8 forum to some length, I think the concensus was it didn't make a great improvement.

Joe's experience is exactly the way that they work. A tank should help and smooth it out some. I built one out of a quart juice tin can, much like the ones used in the 70's. I will use it on my Speedster windshield, but I dunno for sure if it will work, as I am not on the road yet.

I did, on Sonny Greenberg's '36 Lincoln Model "K". Used a Mo-Par square one & hid it in the frame rail, behind the transmission.

Paul, we're tickled that you're able to drive now!!
By the way, the EV8 forum is DEAD WRONG on their concensus that a vacuum reservoir, with a PROPERLY installed check valve DOESN'T help!!! It is NOT a fix for a SICK wiper motor, though!

Rain-X to the rescue!

I use the vacuum wiper and find that when it stops on acceleration I just back off the gas a tad and I get a few sweeps of the wiper which clears the screen for a while . Doesn't seem to be a big issue. If its raining so hard that this techique isn't good enough its raining to hard to be accelerating!

do you guys also use a one - way check valve in combo with it? has anyone tried it that way? A universal vacuum tank can be purchased from any auto parts store

That is what I am doing, check valve between the canister and intake source, placed so the air can only move towards the manifold. When manifold vacuum is reduced the valve should close "trapping vacuum" in the tank. Over on the AACA Forums, someone mentioned that he got a few wipes with the wipers, after the engine was shut down. Just using the stored vacuum. I figure with rain-x and the engine running, it should be an improvement.

Most of the valves i have seen are one way full time

I had a 56chevy when I was 17. it too had a vacuum wiper system.. You learn how to drive it in the rain and make the necessary corrections needed to make a safe drive. No big deal that I remember.

Chief put an "Electro-Vac"--6 volt vacuum pump on Hezzie, his '52 Chev. P.U. Can't locate any info on them.

Yes, maybe I wrote line wrong. It is a regular check valve, placed in the line to allow air to move towards the manifold, since it can be installed in either direction. Looks kinda' like this.

they have a vacuum side so it needs to be installed one way otherwise it wont work. it usually marked or you can just suck on it

Before I switched to an electric wiper on mine, I had a good size vacuum tank under the floor on the passenger side. I also used a check valve. I used to get two to three swings after turning the engine off. I really do like the electric motor better though. Right after switching to electric, I changed to 12 volts and rewound the field with more turns of thinner wire.
