Re: [Chevelle-list] Manifold vacuum fitting?

Pelle,   You can use a "T" fitting so both the power brake booster and the PCV can be attached to the base of the carb.   Herb -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Pelle Chevelle Sent: Monday, September 18, 2006 3:43 AM To: [EMAIL PROTECTED]; 'The Chevelle Mailing List' Subject: Re: [Chevelle-list] Manifold vacuum fitting? 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?   Pelle     Från: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] För Karl Groves Skickat: den 18 september 2006 03:08 Till: 'Carl Ziegler'; 'The Chevelle Mailing List' Ämne: Re: [Chevelle-list] Manifold 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.
