Do not change anything unless the test tells you which part is defective.
Disconnect the fuel -gage wire at the sending unit. Then turn the ignition key to the ON postion to provide power to the instrument panel. With the wire unhooked and the key on, look at the fuel-gage reading. If the gage is operating properly, it will read either " completely full or completely empty" depending on the make and model
nest, take the end of the disconnected wire that leads to the fuel gage and connect it to the metal part of the vehicle frame. If the gage is operating it will read either completety full or completely empty.
If the gage respond to this test, it's working correctely. However if the gage does not respond to the test at all, then the sending unit need to be replace.
