Vacuum port thread/pitch on carter 1bb

[Ajgkirkwood]

Would anyone know the tread/pitch used on a carter 1 barrel carb. Seems I’ll need one with decent length and with a step in the end so the vacuum line will seat down? Doesn’t appear the threads go all the way?

Port is 1/8” NPT.  Get an inverted flare fitting and use a metal brake line or make up

your own from your favorite suitable tubing.
