Have the 25383922 intake manifold(seen it called both TBSS & truck). I want to run a vac line to an external aftermarket return regulator(at least I assume there should be one like on my TPI car).

Where or what adapter do i need to make this work? There is a plugged nipple on top of the intake but is there any cleaner side options? Other than a brake booster line Tee? The Cheap 92 TB it came with has a large capped port.

About to order from Jegs and Summit so would like to figure out if i need an adapter or w/e

i like to tap the removable 90 degree hose adapter thats on the top center. push lock works well.

This engine already has a larger size nipple/port there. I'll prob use a reducer off it at the least. Thought there may be at least a smaller pop-in option, to skip the adapter

Actually you got a closer pic? Not sure i got what you meant.

Ok think i finally found an example and looks like there are two options But since I don't wanna pull the intake atm, I'll prob just use a hose stepdown adapter

that fitting comes out when you rotate it 90 degrees.
cut the nipple off and tap it for 1/8 npt and thread a push lock fitting into it
