That is the set up I have, However, my paper 10micron is also described as a filter/separator. I may remove the separator with with drainable bowl as I have experinced a problem with the drain not shutting off completely and although there was no noticeable fuel leak it did suck air and prevented the system from priming. It is also in a position where it is difficult to see and get to. I carry two spare spin on 10 micron cartridges ( and a strap wrench) as they are so cheap.
