Upper Radiator Hose Pressure??

Well, my Recovery Tank or whatever it is, is quite Long, has place for a rubber hose connection on it to a tube that goes into the bottom of the tank and then another tube on the other side of the tank that goes from the top of the tank to the bottom and is open on the bottom (overflow) and holds about 3 qts of coolant if I guess right. It's a got a 1 qt and 2 qt line on it.

I'll be in Newell Tomorrow and I think they have a small auto selection there at their hardware store that might have a Radiator Cap. If So I will pick up one or two there. Otherwise, will have to wait till Saturday.

The Harbor Freight Pressure tester has some pretty fairly Decent Reviews and I have bought lots of things from there that are still going strong.
