Thanks for the tipoff, John.
I totally replaced the overflow bottle and tubing AND (IIRC) the radiator cap with the proper 9.0 psi rating.

Be sure there are zero micro cracks in the overflow return hose. If it can suck any air it will not refill radiator. Also inspect radiator cap well.
If outer seal is worn or shifted and mushed, it may not pull coolant back in. Also check the spring and action on the center poppet valve. I recently
had a poppet valve spring valve spring fail so cap would build zero pressure, even though pressure seal and spring were fine.
