I would like to replace the standard fuel filter/water seperator on my Mercruiser 5.7LX engine with a Racor unit with metal bowl and water drain plug. In my search I see only a replacement for Mercruiser part #35-604941-1. The Mercruiser part number listed for my fuel filter/water seperator is #35-807172. Has anyone with a 5.7LX engine installed a Racor filter? If so, what Racor model number should be used - the B32020MAM?
