Topic: Vacuum to power brakes and automatic transmission

[momsmustang]

I have a 1966 mustang with a 289 engine, power brakes and power steering. Currently both the metal line to the power brakes and the metal line to the transmission are connected to a fitting in the rear of the intake manifold. Looking in Bob Mannel's engine book he states on cars with both power brakes and automatic transmission there is a single line off the intake manifold that goes to the power brake booster and a special fitting is used at the booster to connect the vacuum line to the transmission.

Does anyone have some information such as a picture and part number?

That begs the question as to why a fitting exists for the intake manifold to connect 2 hard lines.

Thanks for the assistance.

I just went through a similar situation with my 65 Fastback.  One fitting is used for the hard line connections to the intake manifold.  This post should help.

I can't confirm if the 66 connections are the same though.  Maybe others will chime in. 


Edit: The guy on ebay still has a fitting available if you need it.  Its not cheap, $40.
