Fuel Filter
I have a carb and seriously recommend putting a "flowezy" filter (6L something) with a 74 micron filter in line. The Facet pump as well as the FF transducer don't like "junk" in them and can clog. I put one in after the fuel selector in the center section, cleaning once a year is no big deal. If you do a search there was just a recent discussion on filters as they related to FI which has the Flowezy part number that has the AN fitting etc..
