Hello,

I have a 2001 310 SD with twin Mercruiser 350 MAG MPI (V-Drive).

While troubleshooting a RPM drop while on cruise speed, I found debris in the fuel boost pump screen.

My mech suggested to install an extra fuel-water separator filter with inspection bowl, between the fuel tank and the boost pump. My only doubt is that, according to the engine's service manual, no extra filter should be installed.

Has anybody faced he same problem and installed an extra filter? What type of filter? Results?
