B18 with dual HS6 carbs and the metal fuel line has a little rubber bushing where line runs up to above the manifold. Part # seems to be 665335-6 per my old parts book. It is getting crusty and I plan to rebuild the carbs soon, and don’t thing the rubber will survive removal. I don’t see that item listed in any of the usual places. I assume there is a generic equivalent at the hardware store, but thought I’d ask if anyone knows who has the right part I can buy.

I have one on my PV but most people just run a rubber hose instead of the metal pipe. Can't find one anywhere either.

I hate to switch since my hard line is still okay. Looks right with the original fuel pump.
I found a close match at the hardware store but would love to find the exact match if possible.
