Unfortunately replacing the fuel filter religiously will not affect what you are seeing.

Most of that crap came from when you unscrewed the fuel lines.

That looks normal for any LB7.

I replaced my fuel filter the other day and noticed something in the lower section where the WIF goes. It looked similar to this but was more flakey like. I thought it might have been the inside of the filter rusting away. It wouldnt be able to move past the filter element to the lower section if it was coming from somewhere else. Would it ?

If you found it at the WIF sensor it's probably crap from your tank.

Is it something to be concerned with ? At the time of the filter change I dumped a can of sea foam and diesel kleen
Not unless it is a lot, in which case it will probably plug off the suction in your tank, and you have to clean it... been there done that lol.

Just make sure you're regular with the filter change, no biggie, that's why it's there.

If they are fine leave them alone! All that crap comes when you unscrew them. Do not mess with something that is not broken:D
