Intake Manifold
Hi All,
I have an intake manifold with designation D7TE-AA. It came off a 79 302. The intake has a vacuum port where the brake booster vacuum line connects and several smaller vacuum lines came from (See attached image). This engine was modified because some of the vacuum lines were plugged. I would like a little more info on this intake to know where the vacuum lines go. Any help?
Thanks,
Dave

The vacuum lines can go wherever you want them to, and if you don't need them plug the holes. the only vacuum on an engine that's different from one port to the other is the timed " ported " vacuum on the carburator for your vacuum advance. other than that what goes where is meaningless.

There was a vacuum tree on some engines. Vacuum was used for some emissions stuff like EVAP, and in some vehicles for HVAC controls. Transmission modulator for C4/C6 maybe FMX equipped vehicles. Power brakes of course.
