ON THE OTHER HAND, if it happens to be a magnetic induction-type guage =
(with a rotating wire coil), then wiring polarity at the gauge obviously =
matters. It would be possible to switch the wires at the gauge and get =
backwards results.
I'd have to take a closer look at my fuel guage to know for sure what =
type it is. I suspect that it's the bi-metal-strip-type gauge.
By the way, the reasons for using heated bi-metal strips in gauges =
include: considerably lower cost of manufacture, greater vibration/shock =
resistance, a slower response curve (so that sloshing fuel doesn't cause =
the needle to bounce around as much), and natural "dampening" of =
movement to prevent bouncing due to bumps in the road. A magnetic gauge =
can be inductively dampened, but not quite as effectively.

Sorry if this is a silly suggestion, but have you checked that the
battery and the guage are connected the right way round? Might be that
simple. Gordon 8-) (US MV fuel guages are 'approximate' anyway,
that's what jerry cans are for)
