This is my previous fuel filter: https://bobistheoilguy.com/forums/t...x-fuel-filter-in-use-for-13-000-miles.354368/
This filter was in use for 18,000 miles of which most were pulling. The DIC said the filter should be changed at about 15,000 miles, but that didn't work into my use at the time, so it got changed a bit late. From the looks of the filter, it could have gone much longer. I cut this one apart and took pictures of the internals. The main paper element is backed by another filter element and a last resort screen. The filter is well made and needs to be to keep dirt out of the common-rail fuel system.
New and used side by side
Dirty side of main element
Clean side of main element
Secondary element
Secondary element and the last resort screen. Notice the large piece of fiber on the screen?
