I want to apologize in advance if this has been covered before. I was unsuccessful in locating any threads on the topic. I am getting ready to replace the fuel filter on my FASS. Currently, I am using a Fleetguard HF6338 (10 micron). My question is whether it should be 10 or 3 micron? The FASS supplements the OEM filters and pump. Anyone care to share any thoughts? Thanks and have a terrific New Year!
If it came with the 10 micron one then that's the one that I would use. If that's one that you had previously replaced it with then that could be a different situation, but if it came with that one, then that is the one that I would do.
I don't use the supplemental one, I use the fuel replacement one, but I can't remember if it's 10 or 3 at this time, I don't replace it nearly as much as the one at the engine.
Thanks, Tex25025. I replaced the original with the 6338 but upon reflection, and the need to change the filter I was wondering if I should be going to the 3 micron, given 6.0L's known fuel/injector issues?

These filters on the FASS are a little bit longer lasting then the Ford OEM filters. If you get bad fuel, that'll run the risk no matter what filter you get in the longer run. If it makes you feel better, then by all means get it, I don't see the harm in that. It certainly won't hurt the truck and if it makes you feel better then go for it.
