[urq] UrQ Fuel Filter Size

[AF]

My UrQ was almost not running after a track day a month ago. Missing badly.
Pulled the codes from the ABZ motor, saw lots of misfires counted, but I
have tracked it down to clogged injectors. Completely clogged. The guy who
cleaned them asked if the car was running. So I must have a crappy fuel
tank. Figures. Question: What micron does the stock UrQ fuel filter (0 450
905 143) filter to? Is it 5 micron? After investigating this, it seems I
might want a better filter? Any thoughts? I mean why is all this crud
getting past the fuel flter? Thanks for any thoughts.
