Good To Know

Q: How often should this diesel fuel filter be replaced? A: Most Ram 6.7L Cummins owners replace the fuel filter at the interval in their owner's manual, often around every 15,000 miles, or sooner when fuel quality is poor. A clogged filter can cause hard starting, rough running, or a loss of power.

Q: Does this filter include the water drain and sensor ports? A: The filter is built to match the factory housing used on 2019-2022 Ram 2500, 3500, and 4500 diesel trucks. Confirm your housing style and part number against your original filter before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
