To test the gauge, use a variable resistor you can get from RS or other electronic supply store, or fixed resistors with these values: Full - 37.5 ohms Empty - 290.0 ohms do this directly at the terminals behind the clock assembly, IIRC to avoid intoducing error from the wiring between the sender and gauge. Use a known good 12v supply and separate ground to chassis. Then test the wiring between using a voltmeter for continuity, especially the ground connection. Clean up all of the contacts between the two points. The ground point for the sender is on the crossmember above the sender and is a real bear to get to and loosen unless you drop your tank. You can also check the sender for those two resistance readings to see if it is in spec.
