This is the original fuel filter run since the truck was new and changed at 13,000 miles. The black crud on the fuel filter is usual with this duration of miles and fuel burned. I estimate 1000 gallons of fuel has been run through this filter.
Multi-layer depth filtration media and the spots you see are where the layers are "welded" together.Wayne - what are the white "holes"? Is there a secondary media behind this one?
Yes, a very fine screen on both sides of secondary media. They are serious about filtering the fuel and making sure that no filter media can make it to the fuel pump or injectors should it break loose.Is there a secondary media behind this one?
Will do.Interesting. Bring it to HPL in August; I'd like to see it!

Ford/Motorcraft 6.0L Powerstroke FD-4616 Fuel Filter 15,689 Miles
Removed from my 2007 Ford F-350 today. These combo filters were run 15,689 Miles & 342.4 Hours. There was some rusty crusty stuff behind the water filter screen which is somewhat surprising considering how chunky some of the particles were. Primary is a 10 micron & Secondary filter is 4 micron...bobistheoilguy.com
Your primary is much cleaner than mine at 15k miles. I must be buying some dirty fuel at the truck stops on the interstate.
See how black my filter is:

Yes, I believe heat is mostly the source of aspaltenes. I run Howes or Power Service all the time and it makes a difference. I'll post a picture of the latest fuel filter soon.I remembered our conversation about how your fuel filter was dirty looking & stumbled upon the link below talking about why a fuel filter looks sooty. Essentially, from Aspaltenes & it sounds like heat is what causes it to happen.
always replace with delco. I used to change mine every 10-15. Do you have the brass bleeder plug or have you kept the plastic one?ACDelco
I have the factory plastic plug and never take it out, as I see no reason to.always replace with delco. I used to change mine every 10-15. Do you have the brass bleeder plug or have you kept the plastic one?
When it breaks get a brass one. It is a bleeder for priming. instead of filling the filter. The plastic ones get stuck and when you do need to use it, they have been known to break. Happened to me. Was a big deal as no one local had one in stock, had to go to stealership.I have the factory plastic plug and never take it out, as I see no reason to.
I don't manually prime the fuel filter. Since GM put the lift pump in beginning with the L5P in 2017, all you do is turn the ignition switch to accessory and listen for the lift pump to stop running. Then start it up and your done.When it breaks get a brass one. It is a bleeder for priming. instead of filling the filter.

The problem with extending the fuel filter change interval is low fuel flow when the filter starts to become plugged. You do not want this to happen, because you're pretty much parked until you can get a new fuel filter.In any other 'application' a filter that clean would have people shouting, "Double the interval".
I suppose one bad load of fuel can whack one of those filters.
Changing is just "aggressive preventative maintenance" in a diesel.
