Both of Blondie's '83 'Wings had their original hoses on them when sold, as did my '83 and an '86. They're still on the road with the OEM pieces. I bought extras "just in case" but never had to use them.
Ike, Blondie and myself changed the hoses on Ike's 2001 Standard last fall. They were still in serviceable condition.
It's amazing that they would last that long! Wow
