fuel gauge does not register right

Asked by for the 2000 Chevrolet Impala
Most likely it is the fuel tank sender unit (it could be an instrument or wiring issue so it needs to be properly checked out before assuming the sender unit is bad). There is a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
