Mal, did your '38 Eight have radiator shutters? Given the age of the Marmon it probably has shutters too. This may have something to do with the recirculation routing. Don't know, just thinking out loud. This would not necessarily apply to the '37 Six which did not have shutters.

The recirculation routing may have been a holdover practice. This would be something like clothes pins on a pressurized fuel pump to carburetor gas line to cure vapor lock. They were added to early gravity fed non-pressurized gas lines to increase area for heat dissipation, which may have helped with vapor locking.
