Mooney-Shiner Posted Monday at 08:34 PM Report Posted Monday at 08:34 PM I owned my plane for 5 years, but never cleaned the fuel finger filter. I also can't find any mention of this cleaning in the maintenance records. Has anyone done their finger filters? Quote
EricJ Posted Monday at 08:40 PM Report Posted Monday at 08:40 PM That's the fuel pump output screen. The "finger filter" is in the fuel servo, downstream from this filter. It's not a bad idea to check both during annual inspection. 1 Quote

I got everyone confused when I started talking about the finger screens. But I will ask my A&P to so the fuel servo filter service as well. Edited Monday at 10:00 PM by Mooney-Shiner 1 Quote
carusoam Posted Monday at 11:23 PM Report Posted Monday at 11:23 PM (edited) Each of the screens in the fuel system serve a specific purpose… they help identify something old that is falling apart… Sooo…. As a new owner of a machine, it is a great idea to verify that each screen is free of debris… fuel pick-up screen… often catches stuff that got into the tank when fueling, or catches sealant that is flaking off… and, each fuel cap has two o-rings in them that are happy to age, oxidize and leave bits floating around… Fuel separator/selector screen… catches rust particles that flake off the older fuel necks that were originally made out of steel… (pre J) Fuel pump screen… some pump impellers were made of inferior materials… they can be found on the screen. Some fuel pumps have been left running for extended periods of time… oops. there are some rubber parts in the fuel servo including a multi layer-rubber hose in some planes… looks good on the outside, falling apart on the inside… these supply a small speck of rubber to test your ability to recognize a semi-blocked fuel injector… These things happen to only a few planes of the entire fleet… each year. not very common, but best to check when able… Gives a good reason to have an engine monitor if you want an update. PP thoughts only, not mechanically inclined… Best regards, -a- Edited Monday at 11:26 PM by carusoam 1 1 Quote
