Carb question/identification.

Yes that is exactly what I was talking about, sorry I should have been more clear.

I guess I was mainly just seeing if I were to machine a set which I will probably do, if I could essentially just measure the inside of the fuel tee, and be in the ballpark without trying to hit it dead nuts.  
Thank you! 

Perfect, I was actually looking through and it looks as if somebody has made the one between the carbs, in the same way you did.  

Looks like they essentially got the correct diameter piece, drilled and screwed in then soldered a little nipple onto it.  

I am a tool maker, so I have access to all of the machinery that would be necessary, so I will probably just pop some stock on the lathe and turn down some new straight connectors, as well as replace the middle t with one I've machines, just for looks sake.  
 And yes when I said earlier mine has two of the t's, it does have two of the plastic teas, and then of course that center tee between the carbs.  
So since I have a lot of scrap, I will probably make it out of some 7075.  
 

I made the Tee's for these carbs...
