Some tension which required rear wheel removal. It's those compressed air impact wrenches, the kind that make men feel like men around lug nuts. Those of us who have elegant wrists and a Serbian capacity to cast down scorn upon impact wrench uses, always do find that a lug nut that's been visited by an impact wrench something of an effort to loosen.
On the darker side lie the manufacturers of fuel connectors. About them I have
very little good to say. Some fuel connectors are basically little bits of
perished plastic that require special tools to unloosen, so are probably easier
to replace, which means cutting the fuel line. Nor do the manufacturers of motor
vehicles grant any vehicle any more fuel line than is absolutely necessary at
the point of manufacture. I call that uncaring.
