On the alloy block pictures the green arrows do point to the "oil out" port (for the 107 configuration)(126 "oil out" is via the base of the filter). That flow goes to the cooler and then returns to either the filter base (107), or the filter can (126).
Filter bases and/or cans may or may not be drilled/tapped for the fittings.

Even if the cooler is blocked or removed, pressure is not affected because the cooler bypass valve will open.
