Thanks for digging in those receipts Corky! Much appreciate. I hope you didn’t add them up Mine is a ‘79 too. I did replace the hi pressure hose about 2 years ago ( equates to 100 miles LOL.) I had the same problem that someone else did. I bought a brand new hose and it leaked at the fitting at the gearbox. and after trying all kinds of other solutions none that worked, I finally broke down and ordered another new hose from a different source (I think it was Rock Island) and that one fit with no leak. and you could feel the difference when you threaded it in. I’ll just probably keep that hose for now since it’s essentially brand new.
