Maybe the female threaded connector could be drilled and tapped for 1/8" pipe thread for the schrader valve? Any other ideas?
Use a magnet to see if it's steel. If not, don't expect JB to hold. Great stuff, but I wouldn't use it for this. I would make up the brass T fitting. What about an AC or Fram filter? You want to be able to measure pressure while the engine is running at all speeds, not just when the key is ON.
