dont know the link, but you dont have to take the beak off,
take off side pannel's
take off small plastic bits above injcetors
remove fuel filler
now undo main tank pannel you can leave the small pannels on main one
the rest can be seen.
to paint the tank panel you do not have to remove the fuel tank,the painted panel comes of seperatly,beak removal is staight forward just remove bits until it comes off
