Checked the RH tank we filled a week ago and it is now officially leak free.
Installed two additional 7/16" hardware store bolts in the spar to help carry the extra weight of the fuel and installed all the mounting screws in the LH tank.
Plugged the fuel pickup, installed the drain and fabricated a temporary vent line.
Transferred the fuel from the RH to the LH tank and checked for leaks. Once again everything looks good but we'll conclude after a week.
