I have a 99 24v and it takes a cartridge filter FS19579. I think this has a 10 micron rating. Is there an other cartridge available that will filter even better? I was thinking of a 5 or even a 2 micron filter.

 

I don't know about a finer factory cartridge filter but I did away with the factory fuel filter all together and I run A Baldwin BF 1212 4 micron filter on a donaldson base with 1/2'' lines . The filter is about 8 1/2'' tall and didn't drop fuel pressure, the factory cartridge with a smaaler micro rating would get restrictive real fast
