I finished up the tank bay covers by cutting the counter sink in the stiffeners. Panels and stiffeners just need to be primed now then I can rivet the stiffeners on.
Next was to finish up the cross tank vent line. I ordered more supplies including the check valve for the cross vent. It's a nice little device but a little spendy. It will keep fuel from cross feeding from the main tank to the aux tank. I got the idea from Georg Himmeroeder: http://homepage.mac.com/ghim/Bearhawk/page55/page57/page57.html
I reinstalled the aux tank on the left wing and installed the cross vent line with the check valve. I still need to secure the check valve to the frame.
