Yup. You may be able to fix the sending unit. This was a somewhat common problem on Chrysler minivans in the early to mid '90s. The symptom always was the gauge read correctly from "full" to "1/2" and from "1/4" to "empty", and it dropped to "empty" any time the level was between "1/4" and "1/2". The fix was to lift the fuel pump assembly part-way out of the tank, bend a small plastic finger to allow the float arm to be slid off, then bend the metal tab slightly on the arm so it made better contact. Pop the arm back on and put it all together. The factory-recommended repair was to replace the sending unit, but chances are it would develop the same problem in a few years.
Your sending unit has to be unbolted from the pump housing. Once removed, look for a moving contact that can be bent to put more pressure on it.
