[Mgs] Fuel Gauge Calibration

[Ron Fine]

I am looking for information on how to calibrate the fuel gauge on my '66 MGB.
I am very familiar with the MGAGURU.COM web site and I used the information
there to successfully calibrate a fuel gauge on my Healey but the gauge in the
later MGB is of a different design.  There is a bimetal heated arm that bends
in response to current through the sending unit to ground and there are two
adjustment available to the mountings of the bimetal strip and the tensioning
spring but I don't know the current to use to make the adjustments.  Is there
some place I can look to find the resistance reading for the sending unit for
E, 1/2 and F ??

Thanks,
Ron
