Try this:
Unplug the fuel sender unit and short the three wires in the connector together. One comes from the fuel gauge, one comes from the low fuel warning light, and the third (usually the middle or black wire) goes to earth/ground. With the wires shorted together, turn the ignition to On (you don't need to start it) and you should get a Full reading on the guage, plus the Low Fuel Warning light on. If you do, everything's okay except for the new sender unit! (...sometimes new ones are bad.)
If you don't get the proper indications, go back and short the three connector wires to a good ground, then repeat the test. If this now gives the proper indications (Full with Low Fuel light on), it means the ground connection is bad from your connector and you'll have to trace that down. That's your next likely source of a problem.
If you still don't get the proper indications, the problem may be with a fuse, the gauge itself, or connections to it.
