My sump plug has, I think, fallen out again. I looked at Lycoming SB564A. I'll check to make sure my screen is the right length. I'll also try to see if the plug is loose with the fitting and screen installed, but the hose removed. I'm pretty sure the o-ring is correct. I got it from Aviat last summer
But, I noticed in Lycoming's drawing, that they don't show a washer between the fitting and the sump. Maybe the picture below will show what I mean. Do you guys have a washer there?
