This post reminded me of the "sock" type filters which looked more like a pant leg, that I became very familiar with as a 15 year old grease monkey/yard guy. TS, I know you are very familiar too. Cummins 743s primary filter was sometimes in the pan, behind the oil pump or hanging somewhere else. The hardest thing was showing the boss all the "gold and silver" I found when turning the sock inside out...Which brings around the DD system for filtration. All cartridge, filters and housings can
be inspected before and after use. It has it's pluses, yes it can be messy but done right
the mess can be kept under control. Because fuel filters are cartridge housings can be
checked for high pressure fuel pump failure, it will leave very fine metal particles in
bottom of housings and elements can be checked on the spot for metal fuel or oil.

I’m gonna bump this thread because I’m disappointed with the light duty oil filter market at this moment. There has been so much movement and bankruptcy within the filter industry, it’s very difficult to figure out the marketplace.
For example, I’m been hearing quality control reports about Motorcraft Purolator Mann+Hummel. And, since I do maintenance on Superdutys the FL-820-S is a popular filter.
So, I had a chance to cut one open today, afraid to look, and yes, the filter media is breaching just like folks are saying. In this instance, it’s just the glued seam coming apart. 3,200 miles of use.
I haven’t heard any quality control complaints about the FL 2124-S. The Stroker Broh’s would be pitching a fit about them, if there was.. Just be careful where you purchase them because it’s one of the most counterfeited filters in the marketplace.
Looks like the latest version is a decent filter with full synthetic media and 20 micron rating. I’m not sure who manufactures it.
