After leak testing the tank I filled the tank with fuel and set it outside on a flat table for 14 days. This should allow the tank to take final shape for installation in the wing.
On image 1 you will see that the tanks are pretty flat when delivered.
Image 2 shows the result after 14 days. The righthand wingtank has expanded quite a bit compared to the lefthand wingtank which still has to undergo the procedure. The filler neck of the righthand wingtank has raised a lot.
Righthand tank is now ready for installation into the righthand wing.
