I purchased a FAST Intake under a scratch and dent sale kind of purchase. The barb on the backside of the manifold that is used for vacuum to the brakes was broke off. I need to drill that out and install a new vacuum port.
My question is what kind of material would use to adhear the new vacuum fitting to the intake. Some kind of Composite material? Would a JB Weld work?

JB weld is great stuff but no way in hell I would fully trust it for the brake vacuum. I assume the barb is broke kinda clean off? I would clean up the brake and tap the hole and get a threaded barb to go into the manifold. I would use the JB weld on the threads to lock the barb in place permantly. No RTV.
They make these in 90 degree also if you donn't have room for straight off the manifold.

Thank You Sir! That sounds like a winning approach.
I'm circling back around on this topic that I posted a year ago. Its time to address this broken barb connection. I'm looking at it and I find that an 1/8" barb would be used for the brakes. That is what I was told when I purchased it.
What do you think the broken barb connection supplies vacuum too?
Npp vacumn port, the repair is easy if you need the port of not, but will need to lathe up a metal fitting to do the repair if you are going to use the NPP vacumn port. If not, the RTV on a bolt, to just plug the port if not going to get used
Hence the port has a reducer on it, so if NPP hose does have a leak, not a great deal of vacumn lose to the kill the motor.
So fitting like this, way too vaccum can pass through the nipple in the first place, and either it if used, will need a reducer, or just easy to make a fitting with smaller pass through channel to maintain the needed vacuum flow reducer instead.

My car is a 2005 Base. I don't think it came with NPP exhaust option. What other things could that port feed. Something in the evap system for smog?
