Just passing along some info and a picture. I added the FASS Platinum 95 GPH pump/single filter to the truck 15K miles ago. I left the w/ OEM filter inline. This is my 1st fuel filter change since then. I am using the Parker/Racor S3204S 2 micron vacuum filter on the FASS (it came w/ the FASS) and the Fleetguard FS43252 at the engine. The FASS filter has captured all the black stuff and the OEM filter is clean. On previous changes with just the OEM filter, it captured all the black stuff. Curiously, I have never seen WIF MAL, nor have I seen any water in the Racor S3204S filter (it has a see-thru bowl). I guess the diesel fuel around here has good water separators at the pump.
