Air cleaner connecting tube

[F6Ghostrider VRCC #32501]

So while dismantling my bike to remove the clutch, I see that 4 of the 6 air cleaner connecting tubes have some pretty good sized cracks right at the bend in the material where they slip onto the carburetor.
I'm already going to replace my intake o rings after I finish rebuilding my clutch.  My question is, has anyone replaced those tubes? I see and have confirmed with the parts order guy at hondadirectline that these came with a type of sealant from the factory.
Is it necessary to reseal these upon replacement? If so, what is the best product?
I am not sure at this point if they are leaking, but now is time to replace them.  Especially when they are $9 and some change each.

In case anyone is wondering, 98 Tourer with 165,500 miles.

All comments and words of advise are appreciated.

Just my opinion, I have had my airbox off twice but never had to work with the tubes. I would say if they had sealent from the factory then I would use it. I looked in my two manuals and could not find any info on replacing the tubes. I don't know if they are notched so as to go one way only or not, and it has been a couple of years  for me.

I would see if the sealant is soft or hard and go to the auto store and find something fuel and oil resistant that stickes to plastic and what ever that tube is made from. Alot of different RTV sealents. If you can I would seal them in early so they can cure, I don't know if you will need to move them around while installing the airbox.

The airbox is a bugger to install sometimes, there are many threads on this, the best I found pulls the tubes toward each other using tie straps. Youtube has a video on this. Hopefully someone else has better knowledge for you. Firefighter

The tubes are keyed to the air box so they can only fit one way.  It didn't take long on my Valk for the factory glue to no longer stick.  I replaced the glue with something that has held up since then, but that was a long time ago and I don't remember what I used.  Some have argued that it isn't necessary, but I followed the logic that if some engineer at Honda though it worth the expense to glue it, it doesn't take much of my effort to duplicate it and not be worried about it.
