Fuel filters

I did search the forums but not finding much on the subject...

Last year around this time I performed an exceptional number of maintenance tasks.  This year I'm trimming it down since I put transynd in the transmission and fleetguard ES Compleat OAT don't need to touch the coolant.

When I discussed fuel filters before I mentioned that I have the FS19592 on the wynn system (which is either 25 or 30 microns depending on where you google) and the FS1000 as the secondary fuel filter.  Someone on this forum chastised me for using a 10 micron filter as the final filter but when I am looking around the guidance from cummins, foretravel and others is to use this filter.  Can anyone say for sure whether I should be using a 2 micron filter instead of the 10 (i.e. something changed in cummins recommendations over time) and if so, a part number?

Also I used the WF2123.  I am thinking of doing fuel filters, coolant filter, oil and filter, and air filter annually.  Is this too short or too long of an interval?  We have about 16,000 miles last year but it'll be less this year.  I do realize I am over the max on the oil but I am running synthetic and suspect it will be fine as a one time deal.  Anything else I am missing?  I am going to skip the hydraulic oil and filters since they are more recent thanks to my incident in terrible Iowa, a place I will never venture again.

Also does anyone have a non-baldwin part number for the air filter that has the filter minder hole?  The one I got didn't come with it so I don't know how clogged it is or isn't.

I'll probably order everything from filterbarn.

Still haven't done the rear end oil.  Guess I should get on that at some point.

Generally speaking, all the filters you use are considered nominal micron rated filters. The term "nominal" micron rating typically means that the filter is capable of removing 50% of a specific size particle. If Cummins recommends for instance a 5 micron fuel filter, most new filters will pass particles bigger than that. In my estimation, a filter that has been in service for a while, and is partially plugged, will effectively capture smaller particles, thus protecting the engine more efficiently. I have always had the mindset that anyone changing filters prematurely is causing more damage, and spending more money for unneeded filters. Then of course there are the people that fill their fuel filters up with fuel before screwing them on and creating problems by introducing contaminants into the fuel injection system by doing so. It is fine if you know how to fill the filter, but in a survey I have done over the years conducting job interviews for new hires, about 1 technician in 10 actually knows what direction oils and fuels go through screw on filters. Most technicians will tell you they used clean fuel...yup....I looked too...guess they had super eyes cause I sure couldn't see 2 or 5 micron particles. Air filters generally have a manometer on the system you can visually check..I think the chance of dirt entering an air intake system is very high, every time you mess with the filter.  Some of the newer diesels now require an absolute rated filter.
