Started new thread because Yes it was major thread creep on the forum. This is why I inspect the gascolator on every annual. The pictures below are of a Gascolator I removed from a 150, I don't believe it had ever been off prior to this. You'll see the corrosion that occurs in these fuel strainers, you can see the brass 100 mesh screen, which is supposed to separate the water from the fuel, From the looks of it it has never been cleaned or serviced. The "O" ring is hard and brittle, and the whole assembly is dirty, corroded. Those that believe these do not require inspecting just because they have no AD, are the inspectors you do not want doing your annual.
