Also, keep an eye out for low power/chugging, low fuel pressure or codes for fuel restriction.
We have had 2 with a fuel "flapper" check valve in the intake of the primary fuel water seperator filter in the housing that goes for a crap.
Apparently if you put a Donaldson primary water separator filter on that was made for the none common rail engines it may cause this valve to be damaged. The common rail engines have no Donaldson primary fuel filter crossover available.
The Flapper valve is serviceable separately from the fuel filter housing assembly.
We have also had a couple of the new AHI moduals that are part of the fuel filter housing go for a crap already
I have a 2016 that is a little slow to fire when I start it and I have the chug issue at idle and at low RPM and power does seem to be down and I got a P026C code. Does this sound maybe like that flapper valve? Where is it located and do you have a part number? Thanks
