FS43257 Fuel Filter Assembly 5 Micron for Ram 6.7L Cummins 2007.5-2009

FS43257 is the assembly: one FS43258 element plus the canister with the water-in-fuel sensor port and drain valve. At the next service you only replace the inner element and the canister O-ring.

FS43257 is a direct replacement for the FS43252 single-stage filter used on the 2007.5 to 2009 Ram 6.7L Cummins. Both fit the same housing; the difference is in the element specification, which here is 5 micron at 98.7%.

FS43257 flows 67.26 gph with an 18 g particulate capacity, and the element is burst rated at 50.04 psi. Filtration is 5 micron at 98.7% efficiency.

The canister has the port for the water-in-fuel sensor and a drain valve, but the sensor itself is a separate part that transfers from the old housing. Only the element and the canister O-ring are replaced at a service.

FS43257 fits the Ram 2500, 3500, 4500 and 5500 with the 6.7L Cummins from 2007.5 to 2009, so a 2009 Ram 4500 is covered.
