[Chevelle-list] Manifold vacuum fitting?

[Pelle Chevelle]

I removed the hoses & plugged the fittings just as an experiment & it
doubled the idle rpm!!!

That whole system feels “so so” to me and makes me considering a separate
vacuum pump

for the power brakes!? But first I’ll try a thin film of silicone sealer on
the power brake booster

fitting/grommet to see if it does the trick? Since I only have one vacuum
source at the base
of the carb (PCV) I’ll have to stick with the manifold fitting for the
brakes? Maybe I should 
replace it with a better fitting instead of that flimsy piece?

 

Or should I get an adapter plate with a vacuum fitting?

Just to add a little info:

As Carl said, the fitting pictured is for the trans. The fitting will
probably go in the rear-passenger side of the manifold.

The fitting for the brakes is MUCH bigger around. As Carl said, it'll come
off the back of the carb and will be about 1/2inch in diameter

 

Pelle - 

Getting these wrong (and leaving them unplugged) might be contributing to
your poor idle issues.

The pictured item is for the vacuum to the trans.  It typically has a hard
steel line that goes into that fitting with a short piece of rubber hose to
make the seal.  The power brakes are off the back of the carb on bottom, at
least that is the way my 72 is.
