The tubes marked '40' got to the top of the king pins, and '38' goes to somewhere on the engine block. 42 goes to the back of the mechanical oil pressure guage. If your oiler has been removed, and you have a mechanical oil pressure guage there may just be a tube from the engine block, through the bulkhead and directly to the guage.
