Re: 59 AB engine rebuild
Like JSeery, I'm at a loss about this specific fitting . . . where does it plumb into and what is so special about it? (Other than looks).
It doesn't look like any fitting that I've ever used and it surely isn't pipe thread (somebody mentioned 7/16 NF). It almost looks like it has a diaphragm or one-way valve in it. Where does it go and wouldn't one need a t-fitting to split from it to the distributor and vacuum wipers? Enlighten me boys! B&S |

Re: 59 AB engine rebuild
The fitting is a combined banjo bolt and vac takeoff for the wipers. the banjo bolt holds the vac advance pipe to the manifold and the wipers can be plugged onto the vac tube on the head of the fitting. There does appear to be some sort of diaphragm or valve but I have not dismantled one to look inside. The threas is a unf thread, I don't have one here to check the size but it could very well be 7/16 UNF.

Re: 59 AB engine rebuild
The only reason I could see for using something that obscure would be if you were attempting to be 100% authentic. A normal vacuum fitting would functionally accomplish the same thing.
