With the small one I swapped the inlet and outlet around, I also looked at a similar unit and this was the way it was, so far the outside of the filter has remained totally clean and it's draining nicely , yes I have ignored the instructions and did it the way my brain said it would function better, got to love engineers hey, I've also mounted mine on the engine
Common sense and making errors is far better for learning than instructions. I did the same mate.
