Um, I'm not aware of any oil pressure gauge that screws into the intake manifold?
Do you have a picture of where you plan on installing this gauge?

It is kinda hard to see back there, so it is understandable that you might have thought it threads into the intake. But the oil pressure sender actually goes into the engine block, not the intake manifold.

1/8" NPT = National Pipe Thread. What ever you decide to do, make sure to use only pipe dope, and not anything that contains Teflon. I have seen people crack things when using Teflon since the Teflon reduces any indication as to when something is tight enough. In short, it reduces friction, so you have no idea of how tight it really is. Pipe threads are tapered threads, so all you need is some pipe dope to seal it from leaking. Also, don't use brass fittings, because they might crack from the vibrations, since brass is softer. I speak from experience more than 50 years ago.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.
