I noticed when I took the old Racors out that they were 10 micron, I was under the impression that the primarys filter needs to be 2 microns for a QSB 480. Which size is correct?

10Mic is what it should be! The secondary last chance on the engine is 2Mic. If you use 2 mic on the racor, it will clog up rather quickly catching all the small and large particles.

Thats what I thought Bill...2 microns seemed too small for a primary but needed for the secondary.
It's not only that the filter will clog quickly ...but the engine companys suggest using no smaller then 10 mic due to ..it puts to much strain on the fuel pump.....and you wouldn't like the cost of a new pump10Mic is what it should be!
