Chris,

I was in Heaven when I found the cause of low oil pressure to be a forgotten setscrew that opened the main oil galley to an 8 mm (5/16 inch) hole.

I have a pressurized Model B engine that I built in 1976, so I have an idea of what oil pressure should be.

We are trying to keep costs to a minimum for buyers and that is why a modified Model A oil pump was the second pump tried.

Modifications to the stock Model A oil pump used includes doubling the area of all oil passages and the addition of a 40 PSI relief valve on the side of the oil pump at a location above the dipper tray.

A picture of the modified pump is shown in post 174. The brass cylindrical object is the relief valve available from McMaster Carr.
