Check the wiring to the gauge with a circuit tester - one lead connected to the wire detached from the sender and the other to the terminal on the gauge. Loosen the clips on the hose between the filler and the tank, and take off the hose. This is not uncommon in older cars, where a series of small pinholes barely visible to the naked eye cause a slow, steady loss of fuel.
