making a vacuum tank

[eric wissing]

I want to make one of these for my wipers. I stopped in to an Auto Parts Store and asked about a vacuume valve they looked at me as if there was something wrong with me. (there might be, but that's another story). They said they needed a part#. Does anyone know what I should ask for? I want to use a juice can. What does one use to seal the fittings? Silicone? Ane does the valve go from the can to the manifold so it sucks from the can? I looked at a few on Ebay and they all went higher than I wanted go and I don't want a plastic one. Thanks, Eric

Go to your local junkyard..about any of the Mopars with cruise control has not only the smallinline check valve for your vacuum it also has a decnet reservoir that is injection molded...look for it beneath the battery box in about the area o fhe cruise control actuator...or as they say in crime..follow the vacuum

Eric, I used a plastic power brake check valve for the intake manifold side and a plastic pcv valve with the innards removed for the other. They came with rubber grommets and I used a little silicone seal to make sure they sealed. Total price was between $5-$10.

Tim, Norm thanks. Both ideas are good. I am not sure if the Junk Yards will loet anyone walk through them around here. If they pull the item, it costs more. The older somewhat more friendly junk yards are a thing of the past around here. There used to be one where the old guy would first ask if you were going to steal anything, then he would say go ahead. He also had a herd of goats in the yard to keep weeds down. Muchas gracias, Eric

In California we have Pick-a-part, U-pick-em and Ecology auto parts. They have all the cars lined up in rows by category, all up on heavy pipe stands with fuel tanks and batteries removed. you pay $1 or $2 admission, take in your tools, and go hunting. On the way out you pay for what you found, or leave it behind if it's too expensive. Trouble is, you seldom find anything older than a late 60's vehicle to scavenge. When I drove a 79 Volvo, Pick-a-part was my home away from home. I still think the 70's Volvo overdrives and the rack and pinion power steering units are undiscovered treasures.

The volvo overdrives were discovered bythe model A and early ford guys 15 years ago at least- not many around I think because they snapped them up

I purchased this vacuum reserve tank on eBay a while back. It was described as being a Mopar part used on Mopar vehicles in the 1950's with power brakes. I would like to use it in my car for my wipers if I can find a place for it. It turned out to be bigger than it looked in the pictures on eBay.

I thought they made metal vacuum cannisters that resembled an everyday tin can. Some were shorter, some were taller......attached to the inner fender or firewall. Not sure what models or years they were on.

I went to ebay and put in "vacuum cannister", and got this:

Seriously, though, I kept looking and found this. Sure resembles a juice can. An early- to - mid 70s Ford item. Starting bid of $3 with no bidders yet.

My question is: would just any type of these cannisters work for windshield wipers, or does it have to be a specific kind???

[Plymouthy Adams]

one that will hold vacuum..that is the main requirement...in all seriousiness these can be and I have seen many wild and various tanks...I found a super nice really pretty tank made of stainless...this I will polish and place on the Bigbutt...

I made mine from a grapefruit juice can. The valve goes between the can and the manifold.

Lou, in this area there are still bunches of them to be found. Very compact and strong but need 12 volts to operate.

Eric, I used the same canister that BobT posted, looks like a juice can. I mounted it in the right side wheel well of my P24. Very close to the tire at full right steering lock but it doesn't rub. Here are pics with and without the valve adjustment panel installed. The install came out pretty clean. All that's visible is the two hoses.

Bought this one on the bay a few years back. Working on modifications to use it for my top secret fuel additive for the BIG RACE!
