I did find this part number for a filter/regulator 16117163295 that's about 180 from tischer. This is located within the tank, however.

Information that I have read and have been told by my BMW mechanic.

"Replacing the fuel filter in an E90 is not DIY friendly.
You need special tools and the experience of a real mechanic to be able to do it.
The filter is inside the fuel tank (which is underneath the rear seat).
Replacement involves removal of both the left and right pump/sensor units, and the hoses that connect the left and right fuel tanks. Even real BMW technicians would hate to do this job."

I do wish it was as easy as on my e28... or the e30, e36, e46. Its a 50 dollar part that anyone can do. I've been told that fuel filters and pumps are within the tanks now primarily due to environmental concerns. Not sure if that's a wise move. Anyways, no crappy gas for me, lest my filter clog up sooner.
