I researched heavily in the various diesel platforms before purchasing my F-250 and did so with the understanding the primary weakness in the Ford 6.7L platform is arguably the fuel system. With that in mind, I went into it planning to stay firmly on top of fuel system maintenance. I have drained the fuel filter religiously every 30 days and I just changed the primary and secondary fuel filter for the first time at 15K. The process was not frustrating and totally uneventful (nice YouTube video that goes through the whole process. Despite draining the filter housing about 25 days ago, there were a few droplets of water at the very bottom of the primary filter housing (no photos, my hands were wet with diesel).
One of the biggest issues that I see is the WIF (water in fuel) sensor is mounted too high in the bowl. There could be 4-6 (possibly more) ounces of water before the WIF warning alerted the driver, and at that point, there would certainly be water in the fuel system wreaking havoc. Many PSD owners who have experienced fuel system failure due to water complained the sensor never alerted them--I believe them. To counter the possibility of water related damage, I have used Stanadyne additive since the second tank. I have a sample of Archoil that I am going to try in the near future.
Otherwise, all that is needed is a 32MM socket to remove the primary fuel bowl and an o-ring hook for the primary fuel bowl. Thoughts and comments are welcome.
