    Frank, I agree with the problems that you point out, yet if air is coming out the vertical drain tightness of the carbon does not matter. That would mean that when starting there would be some bubbling. (no vacuum). Do you have any take on why the redesign in 1955 or if a 1955 seal might be used? (Why redesign if the original arrangement was OK?)
    Thanks.
