Those Racor filter systems seem like extreme overkill for the small diesel engines most of our boats have. The amount of oil that is going to be collected is so small, it wouldn't be worth the effort to engineer a return line. I would just attach some sort of collection bottle that could be easily emptied; and even then, you'll probably never find anything in it with the huge filter element in those things.
