I'm trying to figure out which fitting to buy to adapt the brake vacuum line that comes out of the back of the stock quadrajet (81 Corvette). There is a place on the back of the Holley for this, but having trouble identifying the thread. Can anyone assist with this? thanks

from memory I think that is a 1/8" npt thread.
go to a local hardware store and buy a cheap 1/8npt pipe ext.
and try it, to verify size.
Do not force it on, you may crack the carb. base.or cross thread the hole.
remeber npt require a bit of selant on them, I prefer teflon paste.

I did this about a month ago. The Napa by my house had the adaptor fitting that screwed right in. It was a Gates part. I think I still have the plastic bag that it came in to get a part number.

Thanks for the tip on the sealant. I may have to check for a leak there.

man I would appreciate it if I could get that part number

It should be in the box that my carb was in, which is sitting on my work bench in my garage at home. I will check when I get home tonight.

I took the whole carb in to the store with me, along with the hard line that goes to the brake booster.

I bought mine from the local hardware. 1/8npt male to a 1/4npt female fitting.
