Cut and trimmed the fuel vent floor fittings per plans. Still need to glue a screen over the holes. I used the deburring tool to make a depression in the opening to glue to and have the screen recessed. Drilled the Adel clamp holes in the fuse gusset for the vent tubes.Following Dan Checkoway's mounting method for the parking brake, I fabricated a mounting bracket that will mount to the inside of the firewall .
