FASS Drop-In Coalescing Water Separator CWS1010

The CWS1010 is the replacement water separator for the FASS Drop-In Series. Turn14 lists it for DIFSRAM1001 (2010-2018 Ram Cummins) and DIFSFRD1001 (2017-2023 Ford 6.7L Power Stroke). FASS rates it at 10 microns. It has a built-in drain, a 1in-14 thread and an internal post seal.

FASS has a warning if you run it on something other than a Drop-In system. On a Signature Series it can make the system louder because of the tighter media, and on a Signature or Industrial Series it has to go on the suction side. For Drop-In owners it's a straight replacement. Fleets can step up to the FLP1000 Drop-In fleet pack.
