<VV> Fuel Gauge/sender questions

Hi,

 

I did a bit of research and appears that modern fuel gauges work by the
warming of a bimetallic strip as current flows through it. The strip moves
the needle.

 

Is that true of our older Corvair gauges or is the variable current caused
by the variable resistor (the sender) changing the magnetic strength of a
coil - and thereby moving the needle?

 

Thanks,

Bob
