I recently noticed that the inlet and outlet hoses on the secondary fuel filter (the one on the engine) appear to be reversed. The top of the fuel filter on my Yanmar 3QM30F has arrows showing direction of flow which do not agree with the hoses attached. I have not disconnected the hoses, but I have only owned the boat for one year and I am assuming the previous owner mistakenly reversed these hoses. To confirm the correct configuration, should the flow go from the outside to the inside of the filter element or from in to out? Thanks, Mark
