Has anyone converted manual brake cyl. and upgraded to power brakes. If so where did you pick up vacuum for booster.Did you buy a carb spacer with a 3/8 nipple? It is a 69 barracuda front disc rear drum.
Help vacuum pick up converting to power brakes

There is an NPT hole tapped into the back of the intake manifold. All factory intakes have one. On A/C equipped cars, there will be a small vacuum nipple screwed into it. Non A/C, Manual Brake will just have an NPT plug screwed in.
I have everything you need to make a Power Brake conversion for that car. PM me if you need parts

I don't know what PM means. I tried to split off with other nipple on that small nipple with different fitting. Not enough vacuum for both.

OK, that nipple with the one vacuum line coming out of it...you need to replace that with one for power brakes

You need more than a splitter. The brakes need the full 3/8 hose for adequate vacuum.

Do you have a long duration (wild) cam in that engine?

No blueprinted stock cam. I can do a direct to booster only. What do you do with the one to the heater controls

I know I'm right....
Just get a spacer. Youll get the full 3/8 diameter vacuum spud. The booster should not 'take' any vacuum at rest, only hold it once started. If you dont have enough vacuum for both, you have a leak somewhere.

You should be able to find a brass nipple or elbow with the male NPT threads on one end and a hose barb on the other end for the brake hose. I'd drill/tap the side of said fitting for a small 1/8-NPT hose barb. You also may get lucky and find an elbow or nipple that already has a large & small nipple integral to it.
Or splice this into your brake hose once you get it hooked up properly: https://www.summitracing.com/parts/rnb-47345/overview/

Those are exactly what I was thinking he could find. But $50! You can pretty easily make something similar for a lot less $$$.

Okay thanks everyone. I think I am going to get a carb spacer with 3/8 vacuum fitting and use original 1/8 fitting for dash control
Why ask for advice when you are just going to do it wrong? The correct fitting is the way they did it from the factory. Why reinvent the wheel? IMO, as always.
