[AT] fuel sending unit

[Doug Tallman]

John, all a fuel sending unit is just a variable resistor. Different 
mfg's use different resistance values for the gauge so you would need to 
know specs on your particular unit. The sender can be tested with an ohm 
meter. Sometimes the windings or the point that goes across them are 
dirty and I have had luck cleaning them. Sometimes the arm looses 
tension against the windings. Doug T

Unfortunately the gauge doesn't quite agree with the sending units position. It takes a lot of lift to move the gauge off empty and it will not read over 3/4 full. It is a relatively simple setup and I couldn't see anything wrong so I cleaned it off and put it back in. I wonder if the problem is with the gauge or the sending unit?
