Need help finding brass overflow tube/drain

[Coopster54]

Hey guys. I'm in the middle of a rebuild and I got the carbs done and #4 was leaking from the bottom nipple/overflow drain (not the drain screw). I guess I don't know the technical name for it which is making the part hard to find. It has a hairline crack causing it to leak. I thought it was a stuck float, until i took it off and it was still leaking in my hand! I didn't see it at first but, now I know what the problem was. Anyways, I am looking for this brass overflow tube online and can't find it or the correct name/part number. Anyone know where I can find one?

edit: I have heard of people soldering or using JB weld on cracked carb parts, anyone tried this? I think JB weld is impervious to gas when fully dried.
Thanks.

I can't picture the part in question. CV or VM carbs? Why not put the year and model of your bike in your message signature?

Soldering is what I would do to repair a split in the brass tube.

I have soldered before, but I'm worried it could seep through and clog it. It is hairline though so maybe that wont happen. I am nervous to use JB weld as if it got loose it could damage more things. Gonna have to suck it up and solder probably.

Then don't dump a lot of solder on the joint.
