I needed to replace the Filter because when I first started flying the plane I used Auto Fuel as marked on the Wings, I just didn't think about the detrimental effects of the Alcohol (Big Mistake), it started eating away at the tank or stripping out the mold release, and I had to flush my tanks, replace the hoses, clean out the air box, replace the filter, and rebuild the Carbs. I ordered a Fuel Filter from Kitfox. Kitfox sent me an auto fuel filter that was the typical auto in-line push on fuel filter, and it wouldn't work with my flanged inline mounting. I ended up removing the Fuel Filter, it had no labels saying what Model Number it was, it just had Earls Stamped on one of the Hex ends. I did a search trying to find the replacement. The only one I could find was Earl's Fuel Filter 230106, which is a 35 Micron. I have had absolutely no problems with the filter, never clogging. When I purchased it I figure if it works on a Race Car it should work on a plane, and it matched the Housing Size & Shape of the one I was replacing.
I did not realize, and did not find the 85 Micron filter, I guess I need to Call John and ask him which he would recommend using. 35 Microns is a significantly smaller than the 85 Microns. I'm going to drive to the airport and see if I still have the old filter in my tool box.
What are your thoughts?
