I completed the installation of the fuel tank plate yesterday. I had a local sheet metal shop produce the plate. My preference would have been for aluminum (or aluminium), but they said that would crack at the bend for the flange. Consequently, I specified stainless steel. The vertical portion measures 9" square and the top flange is 2" x 9". Thickness is 0.25", so it's very strong and weighs (I'm guessing) 3-4 lbs. It is bonded to the tank with silicone adhesive.
