My RV-8 (O-360, carbureted) has inline fuel filters in the wing roots as is common. My issue with them is that are too hard to access for regular inspection and the ones that are installed just have a flat folded mesh disk about the size of a quarter as the filter media. The other thing I don''t like is having to open the fuel system and repeatedly loosen/tighten the AN fittings to check/clean them. There is likely some pressure drop across these too which is not desirable, especially in hot climes.
Andair makes a better filter with an annular type mesh but it still has the other issues above.
My electric fuel pump has a 70 micron filter that is easy to access and check. It also has a large filter area.
I am considering just eliminating the wing root filters altogether. I still have the pump filter and the last chance filter at the carburetor.
What do you folks think of this idea?
