That might just be the normal 20 gallon Jeep CJ tank sending unit... looks similar. Maybe the 15 gallon as well, but check the stock options for the CJ's and see if that is close. The top ring/attachment might differ, but the inside guts are what you need to match up, along with the input/output tubes.
Irregular or inaccurate fuel gauge readings in your Jeep CJ can be overcome with a new Crown Automotive Fuel Sending Unit. A failing fuel sending unit doesn’t send the correct information to your fuel gauge, leaving you to guess or estimate where your fuel level is at.
