FYI Clint, the overflow tank application in a lot of '50's-'60's British cars uses a plain cap that seals to the top of the radiator flange (no guts to it) on the radiator and a pressurised cap on the O/F tank with an overflow tube from the tank (like from the radiator). I've had several of these vehicles over the years and if you use a pressurised cap on both the siphon system returning coolant to radiator as it cools doesn't work.
