I'm no expert at mounting fuel tanks but I should have thought levelling was largely academic from a practical point of view, though there might be a cosmetic argument if it's way off.
More likely someone was trying to introduce compliance into the tank mountings to protect against rupture due to road shocks etc. There are probably neater ways of doing this. I don't reckon tank mount brackets on most Sevens are all that rigid anyway.
