I have one large filter (78 micron) between the fuel selector and pump. I have never found anything significant in it but that doesn't mean I never will. In my opinion, two filters at the wings are better than one after the fuel selector if you check them regularly and worse if you don't.
RV-9A, Tip-up, Superior O-320, roller lifters, 160HP, WW 200RV, dual impulse slick mags, oil pressure = 65 psi, EGT = 1300F, flight hours = 600+ for all
Simplicity is the art in design.
