Just be careful, Our fuel filter is a 3 stage single filter @3 micron. the cummins are 5 micron. You will go through a set of injectors quickly.
Now, if you run that other filter, BEFORE the ecodiesel OEM filter, you can extend your original filter life even more, and provide the same fine filtration requirements.
I know all this on our trucks more than anyone else as I have experimented extensively with them. If you watch my latest video on the fuel filtration, if I did not have my secondary fuel filter, I would have destroyed my HPFP and injectors as one of my filters destroyed itself.
Also our oem housing has a built in heater unit and water detector in it.
No your not crazy, fuel filtration can triple the life of your fuel system. That was the duramax downfall failure on their injectors was fuel filtration.
They only speced out 7 micron, and it was allowing too much dirt past and was wiping out the injectors every 70k.
The new cummins filter is only a single stage filter (paper)
the ecodiesel has 3 stages.
outer wrapping is for structural strength and integrity and provides a "wicking Effect" to shed off water droplets as well as provides the 3 micron filtration.
the second stage is a cotton wrapping which also provides a 4 micron filtration
the third stage is a 5 micron paper element for final filtration.
We literally have the most high tech finest filter in the entire world in our ecodiesels, yes its more expensive and harder to find, but its worth it.
I am working with an aftermarket company to provide a cheaper solution, their first attempt was a complete failure just like their oil filter was, but like the oil filter they are going back to the drawing board and are going to redesign it based on my experience and testing and feedback.
