Dude the troll is playing with you. Yes they make a small oil pressure gage. I got mine from a motor cycle shop and installed it in the front of the block just back of the water pump mount, passenger side front, there is a hole with a small plug in it, just remove the plug and screw in the oil pressure gage. Put teflon tape on the threads and a finish tightening it up with a small wrench. If you take the plug out first you can take it with you to match up the thread size.
