Thanks for the exhaustive research. That is the second fix with tubes I've seen lately on the web. My tubes are all over 20 years old, and I need to replace them anyway when I get a new fuel petcock soon (my reserve does not work, and I better get one before they quit making them, although I think NH750 (91-03) parts should be available for the next 100 years :-)
And thank you Duchene! Good Dx.
