How Often To Change Fuel Water Separator Filter For 6.7 Cummins

OEM filters do an admirable job of filtering emissions, yet they still may miss certain contaminants. A FASS Filter with Extreme Water Separator (XWS) adds another line of defense for your Cummins vehicle by blocking and preventing extreme water contamination from reaching its injection system. Over the lifetime of your vehicle’s service life this could save thousands in expenses by protecting against costly injection system repairs due to blocked extreme water contamination entering into its injection system.

The 6.7 Cummins diesel trucks come equipped with two fuel filters/water separators; one is mounted under the bed while another can be found on the frame rail in front of their respective tanks; these units must both be drained when water in fuel alert lights come on.

Fuel/water separator filter(s) should be replaced every 15,000 miles or every 12 months, whichever comes first, in order to protect their sensors against contamination by excess water content in fuel; otherwise it may strip diesel of its lubricity, leading to early wear on engines.

This kit contains Mopar 68436631AA and 68157291AA diesel fuel filters to facilitate quick and simple fuel filter replacements. Be mindful to insert only as far into your fuel bowl as the barbed fitting of the fuel/water separator filter will go, otherwise the hose could become stuck. Likewise, consider using high quality additives which reduce water ingestion.

If you have been driving your vehicle for an extended period, its filter should be changed regularly as dirt may enter the fuel and cause engine damage. Aim to replace your filter every 30,000 miles or two years as well as replacing its water separator.

Change your fuel filter often to protect the life and longevity of your 6.7 Cummins diesel truck, and avoid expensive repairs and maintenance services in the future. A clogged filter puts stress on your engine, shortening its lifespan in turn.

At least every other fillup, it is best to drain and replace your fuel/water separator for preventative maintenance purposes. Be sure to drain into clean containers and dispose of properly. This kit includes two OEM Mopar 68436631AA & 68157291AA diesel fuel filters designed specifically to fit 2019 to 2024 Dodge Ram 6.7L Cummins trucks; please be aware that they come equipped with California Proposition 65 warnings.

Filters are one of the least-expensive ways to save on fuel, as well as repairs for clogged filters that could cause engine failure. Though seemingly small parts, filters play an integral role in protecting and prolonging engine life.

Utilizing a dedicated fuel filter socket is recommended as this makes accessing the fuel/water separator easier. We also advise using high-quality oil when changing coolant every 10k miles to help prevent fluid/particulate contamination.

At FuelSmart we recommend draining the water separator before every fuel refill draining a few ounces into a clean container – as a preventive maintenance measure to make sure there’s no water or oil entering your fuel supply system. Make sure you dispose of this waste properly.

6.7 Cummins engines feature fuel filters to protect injectors and high-pressure injection pumps from debris build-up, while simultaneously trapping dirt that could otherwise damage their engines if these filters aren’t changed regularly enough.

As part of preventative maintenance, it’s essential that every other time you fill up, you drain both the primary and auxiliary fuel filters of their contents into clean, clear containers. Just a few ounces drained may help avoid an unwanted water in fuel light/message on your instrument cluster display.

Studies show that switching out an old fuel filter on your vehicle could boost acceleration and economy by 14 percent, according to some estimates. Mopar fuel filters for your Dodge Ram 6.7 diesel pickup can be purchased at any auto parts store.
