What reservoir was used with the foot pump windshield washer set up?
I know what the 72-74 reservoir looks like but I don't seem to be able to find the 70-71 set up.
Should look like this with a nipple on the bottom. I use this for my radiator reservoir.

Thanks a bunch.
A radiator reservoir is what i am going to use it for.
Much appreciated.
I assume the logic is that you don't use the Washer to clean off the windshield, and your radiator spews out making a mess? Doesn't that indicate an overheating issue, or maybe a radiator cap issue?
I don't believe I have ever used the washer either, but do still keep it functional.
I think I have a radiator cap problem.
I don't like the aftermarket catch can so thought I would just put a factory catch in it's place.
It's a track car so I don't put a lot of miles on it so no windshield washer fluid needed at this point.
I have an 18 lb cap and it spewed some fluid the other day into the catch can.
it also blew off the lower radiator hose from the aftermarket aluminum radiator. There isn't much of a lip down there to hold. Tightened the hose up with two clamps and then it spewed into the catch can.
Was suggested to put a 20 lb cap on the radiator. Figured I would just try a replacement 18 first.
Don't like the look.
Don't like how it mounts.
Stock cap is 16lb unless for some reason you need a 18lb one. Have to have the correct cap for the coolant to recirculate from radiator to reservoir and vice versa. This is my set up. Hose attached to the nipple is from the radiator. That hose on the top is a drain in the event the reservoir overflows. Cap that works on mine that looks stock is a Murray Masterpro cap part#7616. That's if this cap fits your radiator.

I'd like to do this too, but isn't the radiator overflow supposed to enter (and suck back) from the top of the tank?
I assumed the bottom nipple would be capped?
I spewed antifreeze last year and it was the rad cap. Bought a reproduction and same issue but not as bad. Soaked the new cap's rubber seal in WD40 to expand it and haven't had a problem since.
Same thing happened to my friend's T/A 10 days ago. His rubber seal was deteriorated beyond belief.

The motor is a 512 stroker that is basically designed for the strip. A few minutes of run at a time.
I have been driving it around town (on drag tires) so it is running more than it's initial intention.
Had read that the 18 lb is what I should be using for this set up since it is not stock by any means.

Ah yes, in your scenario the most important thing is not to spew onto the track (normally a rule). So I think using the washer fluid reservoir makes sense, and would avoid needing a second box. That black one is kinda ugly (:
I think going to a 20lb cap would buy you some time before spewing, allowing the radiator fluid to get hotter, but would likely still spew. Not sure how you plan to get the fluid back out of the reservoir tank either. Maybe just have a valve (similar to the radiator drain) to let it drain into a container once it had cooled.

Correct. The hose you see at the nipple is from the top of the radiator routed along the lower radiator support. So its a long hose. Coolant is moving back and forth from this hose. I knows it works since I notice the level changes in the reservoir. I learned this trick from a post from the Moparts forum to keep things looking stock.
Anyone know what the capacity of the tank?
Would think you'd need 3-4 qts?

2qt and 8ozs or 72 ozs (I just measured using my power washer tank).
Procedure I used was leave the tank empty, fill radiator to full, then drive it to get up to temp. The overflow will go into the tank. It does not go up that much. Then I added about the same amount of coolant into the tank, and that is my minimum. The reservoir fills up to about half. So if for some reason you get the Overheat condition and radiator wants to spew out the max and completely fills up the reservoir, I do have a drain, just like the dedicated reservoirs. That hose you see at the top of the reservoir is the drain for excess overflow which will go to ground. But now, my radiator is always full to the cap vs having an overflow to the ground. Haven't had an overheat condition yet. In a 90 degree day with driving, the level may go up to half, but never close to full.
Thx for the info, 72oz should do the job
From what I've read you need about 20% of this system capacity for expansion.

If you do run with this, use 5/16 overflow hose. The nipple is a bit smaller than the radiator fitting. If you use 3/8 hose, it will be too big for the nipple. 5/16 is a hair to big, but the clamp will stop any leaks.
