So I was quite carefully cleaning the float bowl and as soon as there was an pressure on the overflow tube (if that is what it is called) it broke at the base

Can this be repaired or replaced or do I need to scavenge a part from my other carb?
I'm 99.9% sure it was cracked and about to go. If you look at the pic of the base of the tube the brass has corrosion everywhere but a sliver that must have been holding it on.
