Today I did my first fuel filter service at 15,000 miles (2500 6.7). I noticed that the inside bottom for the front filter housing looked to have sparkly glitter in the bottom of the housing, once the filter cartridge was removed. Almost like there was a shallow bed of brown sand sitting at the bottom. My stomach dropped at first, but then I took a screw driver and tried to swish it around, but it appears that it’s just the reflection in the bottom of the housing. Nothing moved as I swished the screw driver around. I also completely dissected the filter media and it was clean as a whistle; not even a hint of anything was there. So it was obviously just an illusion, but really freaked me out. Has anyone else noticed that?? Wish I would have taken a picture.
