Replacing a fuel gauge sending unit is a complex task that requires careful consideration. It is important to note that many people have regretted replacing a working unit, as the replacements are often not calibrated correctly. Before attempting any replacement, it is recommended to try and preserve the old sender by cleaning it and putting a new float and sock on it. If the needle on your gas gauge doesn't seem to move, you should check for a grounding strap that connects the sending unit and the fuel line from the fuel pump. To replace the sending unit, you do not need to drop the tank. However, it is best to ensure that the fuel level is in the lower third before beginning any work.
