I have a holley 750 vac secondary carb and i had a quick question regarding the vacuum lines on the carb.

Can i use the vacuum line from the back of the base plate on the carb to power my Brakes? Is this crankcase vacuum or carb vacuum?

I was just wondering because i was looking to pluf the crankcase vacuum line and use the carb instead.

Thanks

John

 

The 5/16-3/8" nipple on the rear of the carb is full manifold vacuum. It would be used for PCV or power brakes.
