Fuel sending unit

[Gearhead9992]

OK so I have a 96 s14 bone stock and my gas gage doesn't work so I pulled out my sending unit and found the black resistor looking thing solder had broke front the other resistor so I soldered it back on plugged it all back in and the gas gauge still sit's below E so I pulled it back out and check ohms and all is in spec

So what can I check next I'm going to try and upload a pic of the sending unit so yall can tell if I soldered it right
