It may be possible to add a variable
resistor in series with the gage and tune and calibrate it to the sending
unit. You can simulate and check out all of this off the car if you know the
resistance of the sending unit at various levels. I think the gages are just milliammeters
calibrated to point a needle at E, F or in between in the variable-resistance
6V or 12V system. I think the physics of DC circuits suggests that you will
only have an approximation if you place a fixed resistance in series with the
sender and gage—but all fuel gages I have ever seen are non-linear SWAG’s
and approximations.
Anyone ever had a gage that said F when
the pump kicked off? Or you knew you were out of gas at E? or that ¼, ½ or ¾ really
were that? I’m sure there are good reasons for bad readings, but I am
not impressed with that particular bit of automotive engineering.

Limiter on 56??
Maybe not. It's not shown on the
wiring diagram on page 407 of the '56 Ply FSM.
I just assumed the 12v systems did.
Well then, if it doesn't, can I use a
voltage limiter with a '55 6v fuel gauge?

Roger... Do I have a
voltage limiter on my 1956?? That's news to me.... Jim
