Ok started thinking about where I got the B&W image from then remembered it was out of the Jan 1966 SAE report.
This is what helped me determine what would be a correct line layout.
Again I know this isn’t LAW but it sure helped me out.
I still would love to see anything showing a filter/vapor line layout.
I think we should make this another post
