Original Hoses from 67'

[N601RX]

A while back I re-hosed all my hoses. The Firewall foward ones were newer and in good shape, but the ones behind the panel and under the belley where still the originals.  The one in the picture below was corroded pretty badly when I took the hose ends off. The corrosion really wasn't obvious until the end was removed.  It would be bad to get a 180 deg oil bath while flying along.
