: Demon carb with air gap and PB

Any one running a Demon Carb on an Air Gap and have power brakes? I see a plug for the power brakes vacuum fitting but the bowls on the demon hang over this and getting a fitting on there looks like it will be tight.

The demon has a large vacuum port but I am thinking the PVC valve would go here. Can I tee off that?

Thanks.

Thats what alot of guys do they put a "T" in the port at the back of the carb and share the PCV and Power brakes.

I did the same as above, used the thick phenolic gasket and a street ell to tie in my brakes seperate from vacumn line. Fits very tight under that long bowl carbs. Even had to gring ell down a little for safety.

You really don't want to do this if at all possible. The oil fumes will eventually contaminate the brake booster. I know this sounds weird in a vacuum enviroment but they will ruin the booster.
FYI...There are carb spacers available that come drilled/tapped for a vacuum port. Or, you can do your own...
