I am with you with to many filters. I am going to remove the inline filter. How do you know what microns that the engine mounted filter is? I just replaced it with a Yanmar filter, doesn't say. All and all I am going to use a little throttle when I start up. And a diesel guy told me to use a 2 micron filter in the racor, and just change it more often if needed. But the problem was the same with a 30 micron before I changed to a 2 micron.
Racor filter housings some times have fittings with little check valves in them..
Make sure yours does or fuel will bleed back to the tank.
