1971 Evinrude Fuel Lines

[Jer from CA]

I recently purchased a boat with a 1971 Evinrude 50HP outboard motor, model 50173. The fuel lines are in bad condition because the boat sat for about 15 years. I bought replacement hoses, but I can not tell which hose goes where. I checked out two repair manuals from the local library, but neither shows a fuel flow diagram or a picture of the actual hose arrangement. Can someone maybe provide me with a drawing or direct me to a place where I can get a better understanding of the hose routing.
