From page 6,

"While most fuel filters recommended by engine manufacturers have a nominal pore size of 10 microns, 6 studies by the Southwest Research Institute reveal that the critical particle size for initiating significant abrasive wear in rotary injection fuel pumps and in high-pressure fuel injection systems is from six to seven microns."

What is the stock filter rated for? I'm glad I switched to the CAT/FASS combo!

The Racor PFF50216 fuel filter (supposedly, the same GM filter part# 12633243) has a micron rating of 4 according to Racor.
