I just bought a 2008 Ram 2500 6.7 Cummins. The prior owner installed a Cat filter adapter. It's time to change fuel filters. I now notice there is no rear water seperator like my 2017 had. Is there only one filter on these? Does the Cat filter separate water as well? Is there an aftermarket water seperator I should add? If so, does anyone run Racor filters on there trucks. I come from the marine industry and know Racors work very well. Thank you for any input.
