Fuel inlet tubes at carbs

Just prior to putting everything back I noticed that at the tee piece on the fuel inlet there seems to be a rubber tube at each end of the tee sitting over the main tube, almost like a small rubber collar, however they seem to be not complete, almost like a C in cross section, or alternatively it was a sleeve or collar that's now perished.
Is it a perished sleeve do you think? Should I worry about it, or do I need to get replacements, if so I imagine its a carb strip down job to get them in?
I'm wondering what I'm going to find next!

Have a read of this i think we are talking about the same bits? carbs need splitting to replace, im thinking tyre inner tube segment and a zip tie at either end to seal, its no worse than the rubber collars?!??!

Sure does look like the same piece alright
Tyre inner tubes and zip ties it is, I thought it was the fuel inlet, obviously wasn't looking properley!

It's the passage used when the slides move and displace air. Any leaks will mean that unfiltered air is in conatct with the slides, possibly leading to accelerated wear.
The plastic rings are usually perished at this age, I've run carbs without any filtered air for the slides, I don't think it's a big deal unless you're regularly riding in a dry dusty desert...

Dry dusty desert??????

Well at the moment I have no plans to do the Dakar on it, and living in England our summer seems to generally consist of rain, rain and more rain, I think we had a couple of sunny weeks back in June.
I think I'll leave it be
