WMO/ATF filtering In my gravity feed filtering process I have used a PH8A / 5 Micron whole house water filter then into a Permacool fuel filter for several years. Could gravity feed 5 gallons through the filter system in less than a day. Permacool filter is advertised as a 2 micron filter. I recently changed my filter and replaced the Permacool final filter with a Baldwin part number BF7587 as a final filter. The gravity feed filter time has went from less than a day for 5 Gallons to Now over a week and and about 3 gallons filtered and still 2 gallons to go. From what I have been able to research the Baldwin filter is rated a 2 micron. It would seem that there is a great difference between the filtering quality between the 2 filters. Does anyone have any experience with the Baldwin BF7587 fuel filter? Or any thoughts?
