I agree 100% with everything you say, still, leaks. I have even tried a
slight coat of RTV on the inside of the hose mating surface. Worked for a
while.  I believe you may have hit upon something with the undersized Brazil
hose comment. Thank You. How does one ensure of a German product when
ordering?

Also, I think the orange anti-freeze must have smaller molecules.
