Haven't found any factory photos with the optional filter but did find a few showing the fuel line from pump to carb. From the way the tubing from pump is routed I believe the 40 filters might have been installed just like those on later engines.

On later engines the line was disconnected from the carb, the fitting where the tube connected was removed and a straight close nipple installed in its place. Filter out port was screwed to the nipple and the original tubing fitting was reinstalled at the filter in port. With a slight rebending of the tubing to accommodate the added length of the filter the tubing was then connected to the filter.
