G·PEH Pressure Sensor Adapter Stainless Review

Fit perfectly and everything was exactly as described! Not sure why some had trouble landing. It corresponds to the described size.

Center tap does not have 1/8 NPT threads, 1/8 NPT male front is correct and 1/8 NPT female rear is correct. Tested with several 1/8 NPT parts I have. See photos for details. I've ordered so many t-shirts that are just wrong or got the threads messed up. I will just order one faucet set and make my own lmao.

Looks very high quality, the thread is fine. But in my case the oil pressure port is in front of the intake manifold on my 403 Olds. I bought it to add an Autometer oil pressure sensor in addition to the factory sensor and it was too small for the sender to clean the intake manifold. I ended up buying a McMaster Carr 3-1/2" Schedule 80 stainless steel nipple and made a clamp to keep it from breaking from vibration. Again, as long as you have a gap to do what you want , you can get started.
