Bob, that is the bleed port to the case-- excess oil that makes it past the piston drains back to the case through that.

In order to determine whether your case has the oil bypass modification, it is necessary to probe inside the oil passage that is the inlet to the pressure side of the pump. This passage is under the oil cooler-- with the cooler installed, remove the "S" hose and probe with a wire or better yet, a USB endoscope, all the way into the passage-- on the top side you should feel or visualize the port. An uncut case wil not have the port.
