I concur with Harry's comment. I had the exact same thing happen to me. During my first annual the mechanic did not torque the housing nut properly and after the first flight I noticed a small seepage of fuel around the nut. That was the clue. Partial failure followed shortly after. The mechanic did not have the proper torque wrench and merely used the "I think that's just about right method." Now I hand him my torque wrench and make sure it is done properly.
