It's not worth the effort to install an external filter IMO.

returnless fuel systems filters only filter the fuel the engine uses as opposed the a system with a return line that filters everything...even the 80% that's sent back to the tank....so your filtering less fuel on a returnless system so the filter life is extended 50 000km = 250 000km filter life. you only need to change it when the pump fails.
