Prosealed and riveted on anti-rotation bracket. Also prosealed in the optical fuel warning sensors in both tanks. Unfortunately, I'm sort of stuck here because I need to torque the fuel line bolts and fittings, and my 1/4" drive torque wrench won't fit the 3/8" drive crowsfoot wrench set. I don't have an adapter, so until I can get one, I need to move on to something else. I need to finish up the plumbing before I proseal on the baffle. Maybe the wing cart....
