George you stated,

>>...On an 84 with the big analog clock the fuel & temp gauges have to come off as you remove the clock or remove the back from the clock.  As I was putting this little puzzle back together the sping thing that tensions the fuel needle popped off.  I put it back as carefully as I could but may have distrurbed its tension... ina favorable manner as it turned out.  Other years &/or other gauge clusters may differ. <<

   Yesterday I checked out a Jetta gas gauge that I'd removed.  (transplanted the Jetta's tach into my Tiico Vanagon dash)   This particular unit has an inspection hole in the rear and there are tiny teeth inside so that you can make adjustments using a small screwdriver- large adjustments, it seems. <G>   I'm guessing the instruments were calibrated at the factory before assembly.

   Bentley procedures to deal with a malfunctioning gas guage include either replacing the voltage stabilizer or the gauge.  Adjustment isn't mentioned.  Deviation of one needle width either way is ok- but I think it's kinda sloppy. <EG>
