I installed this fuel filter kit https://www.dieselfuelfilterkits.com/2013-2018-cummins in June 2020.

I have been running with stock filters and the additional 2-micron NanoNet Fleet Guard FF5814 filter.

No problems with my pump yet, but I am also concerned.

I have checked the pump current with all three filters, and the average amperage is 5.7 amps (See attached).

I will check the current with stock filters to compare the difference and report back.
That ff5814 fleetguard is what I run on the front conversion on my BMP setup.

An excellent filter, and I run the FS19683 on the rear one.

I prefer Fleetguard to the CAT filters.
