Why Both Filters Matter
The 6.7L Cummins uses two filter stages. The separator removes water and larger contaminants first; the engine-mounted filter provides final filtration before fuel reaches the high-pressure injection system. Replacing only one leaves half the system on an old element, so both are normally changed together.
Service Notes
Replace at the interval given in your vehicle's maintenance schedule, and more often with biodiesel blends, heavy towing, or poor local fuel quality. Rough idling, reduced power, or hard starting can indicate a restricted filter.
Installation: Follow the procedure in the factory service manual for your vehicle. High-pressure common-rail diesel fuel systems retain pressure after shutdown and must be relieved correctly before any line is opened. If you are not equipped to do this safely, have the filters fitted by a qualified technician.
Please verify fitment against your vehicle and part numbers 68157291AA and 68436631AA before ordering.
