I searched here but didn't find. I have an RV-12 iS with the fuel injected Rotax coming in two weeks and someone said I should screen/filter my fuel to 10 microns before filling the airplane. I use the Flo-Fast system and hand pump and so I ordered in their pump intake screen part 80850 but just realized it is an 80. I buy 92, unleaded no ethanol fuel and transport. My questions are should I pre-filter, and to what size and how can this ne done. Mr Fliter are just 50 microns.
