Result was a dirty filter media, but nothing that would change the world.
I asked him to send it again, but he couldn't manage to find it anymore.
You know, if a fuel filter is not saturated after 50~100k miles, either the fuel is top level clean or the filter doesn't hold the dirt enough.
Fuel here is not clean.

Oh well, thanks for trying anyway.
As for the lack of media replacement options, typically tank filters are gauzes and don't need to be replaced and are simply cleaned (if needed).
I work at a Suzuki dealer, a few months ago we had a 20+year old Wagon R where I need to take the tank pump assem out, their really wasn't much dirt in it and the gauze filter was in good condition (although I think it was a low mileage car).
That reminds me, although you may have found out since otherwise, in the m3 cutters injector thread you replied to a few years ago you intimated that the M3's were somewhat unique in only having a tank filter.
This is definitely not the case, the vast majority of manufacturers switched to tank filters around about the mid 2000s for petrol cars (at least for the UK & EU), e.g Nissan Micra K12 2002>, Suzuki Grand Vitara ~2006>, Ford Focus Mk2 2005> to name a few.
I've not come across, nor heard of these failing or clogging up under normal use, not saying it never happens mind! Just that at best it is rare.
So why would our M3's be uniquely(?) affected by these coarse tank filters?
I don't buy it, unless the filters are disintegrating and splitting open? (Hence wanting to check mine, if I can!).
If so, are other e9xs affected? (335i DI injectors aside
).

It was an automatic fuel injector cleaner/tester. They flowed fine. Everything was within 5% flowrate and no leaks. Wasn't until I put them back in that one failed stuck open and lost a cylinder over the road.

Damn, sorry to hear that
I'm actually looking to get hold of a jammed injector! (to then pay a specialist to determine what's wrong with it). But you're the other side of the pond, so I suspect it would be rather pricey to post.
