Fuel filter change- is this unusually dirty?

[Highcountry]

I did my first fuel filter change today. Thanks everyone who gave me tips on proper documentation. I’d been hoping to do them at the same time as the fuel pump recall repair, but still waiting on that. These have about 12k on them and the filter life monitor was saying 10%.
The front seems quite clean, so maybe I got some mucky fuel and the rear did its job? All in all pretty easy, so I plan to do them at a lesser interval. Just wondering if this is out of the ordinary

normal.

normal.

thanks, this is my first Diesel Truck and first new truck, so I want to take care of it the best I can

Might be normal for some but that's some nasty fuel.

Since my first diesel in 2004, none of mine have ever looked that grungy. Just black colored pleats.

Perhaps it's a regional thing? Pretty dry here in the west/southwest.

It's crazy wet around here. I think I'm going to switch where I get fuel to a place I know has new tanks. I was glad to see the front one seemed clean at least

Filter media looks normal, but that algae substance doesn’t look normal.

Are you running b20? That’s the only time of seen that brown sludgy stuff in a filter.

No, it seemed like maybe it was from
moisture? I’ve never gotten a water alert and the fuel I drained looked clean. Whatever the reason it seems the filter was doing it’s job

Yeah. I had the same experience in my 2013. The rear filter seems to put in the lions share of the work since it sees the fuel first. The engine filter was always clear

Algae by the look of it on the rear but dirty filters are a good sign it means the dirt is in the filter not the injection system…. I would run them to 0% next time

I’ve run diesel power clean consistently, should I run a few tanks with something designed for algae like this? Is algae something that takes hold in a system if you don’t get it out?

I would run it for a couple tanks for sure its cheap insurance
