It looks like I do have the secret fuel screen forward of the electric pump. All these years I never knew. I don't see any reference to continuing maintenance but the SB says that inspecting this at annual is a benefit. Does the screen come out from the front or rear side of the tube? Is washer AN960-916 replaced at the same time? ref:http://www.mooney.com/en/sb/M20-222B.pdf   -Robert
