I think Nurse Julie sells the o-rings for these tubes in viton but check with her first. Do not be tempted to reuse the old o-rings as they will leak and it will be another strip down to replace them.
I pulled one float bowl - silicone, Oring, and some sort of red-orange sealant that is quite hard and difficult to scrape out of the groove.
Yes, that's the tube! Is it available as a part? I haven't yet decided whether I'm going to separate the carbs but those little pieces of tubing would be a critical item!
