Dave, a Racor 500 series is one upgrade I made for my Yanmar or would recommend on any engine. You can open it and check without losing any fuel or making a mess, and a clear bowl at the bottom lets you see if any crud is falling or if you have water in your fuel. I run a 30-micron filter in my Racor and a 10-micron filter on the engine. It seems happy and has been running all night so far. We’re in the C&D Canal heading home to Newport for the summer. Looks like lots of motoring this trip, but the Eng is nicely purring along. Andy (ex C&C 40, Peregrine) Baltic 47 Masquerade
