1944 John Deere Model A Oil Pressure Problems

Since my carburettor for the Beetle has not arrived yet...3 weeks! I have decided to start some work on the Model A. Fixing the oil pressure problem will cost nothing but labor. This fix is not anywhere I can find on the internet, so I hope other people can put this to good use. I had the same problem on the 1945 also. So I am thinking anyone who cannot figure out why their oil pressure is low...this is a really good place to start. I believe that all JD two cylinder tractors from 1941-1946, would have this sort of setup. The newer tractors 47-58? have a different placement of the pressure relieve valve. Starting at 38:30 the Corona Virus politics starts. For those who don't want to listen to that, or for the Trigger Bots who do ,This is the dividing time in the video.
