I measured my tank sender resistance back in 1992 and recorded 75-80 Ohms full and <5 Ohms empty, confirming the previous posting. If you have, or simulate, a full tank and arrange an easy means of short-circuiting it (Green with Black stripe wire) to Chassis (Black wire or body of the gauge) to emulate the empty tank you can recalibrate the gauge yourself though it's mechanical and a fiddle.
Two screws on the back of the gauge hold the physical position of the internal coils and loosening them and moving the assembly about changes where the needle points to for the full and empty resistances. If they appear to be fairly close I would leave them alone; the odds are that they will have used the same sender unit as the Sprite and be identical.
