My hose....
was a score, according to Tom Gasko, these were aftermarket hoses made in Mexico. Newer than OEM.
I am sure you will find a matching PN on Ebay or from some generous member.
With some careful preparation, I think there are spray paints out there that are made for fabric and or vinyl. What ever you do, do not spray spray rubber on the outside to stop leaks. The hose will stiffen up because the braiding "freezes".
