In the 2004 lb7 duramax engines a commen problem they ran into was failing injectors due to air in the fuel causing contact in the injectors as well as not having a small enough micron filter.
I say that to say this. As long as you are the same or better in filtration (micron) the lift pump, or main pump, is not overly straining to maintain fuel pressure to supply fuel to the injectors you can pretty much have whatever filter you want.
I will probably invest in an airdog system and completely delete the factory fuel filter and lift pump. Lb7 duramax guys do it all the time to "cure" injector failure and it also vacuums air out of the lines and slightly improves fuel economy. Plus Airdog boasts a lifetime warranty on there pumps which is a huge improovement over the problem the factory lift pumps are to begin with.
