Why Remove the Mercedes W123 Fuel Tank Sending Unit?

Especially When It's So Easy?

If your fuel level gauge is not reading accurately or the needle jumps around and or your car’s low fuel warning light does not comes on, it is usually a problem with the tubular sending unit in the fuel tank. If you don’t fix it, you may run out of fuel some day when the gauge is reading a quarter of a tank! Replacement units are very expensive new and some are no longer available. With the right knowledge and tools fixing a malfunctioning fuel tank sending unit is not difficult.
