Some of these pictures are dark because it's winter, the hangar doors are closed, and lighting is pretty poor in the hangar right now. Here you can see here one of the fuel sump screens. It's a sink strainer, obviously, but hey, that's what the plans call for and it does the job very well. You can also see the vent and grounding lines, with the recommended additional vent holes near the back corner of the strake drilled into it. The water drains are also installed - I'll try to dig up some better pictures of them later.
