I had also found a post by TOH in which he mentioned the rusting tube and the testing of it using air. With the fluid as low as I now have it, I do not see any turbulence except by the PTO shaft.
Neither my FO-4 (copyright 1953) or my New Holland Assembly Manual and Service Parts Catalog show that tube.
In line with the "try the easy first" idea I think I shall drain, flush and refill.
Will Diesel Fuel or Heating Oil work? I have no idea where one would get Kerosene any more.
