Damped sender unit
Fuel delivery modules generally have a fluid-level sensor that measures the fuel level using a lever arm. The lever arm can be moved easily. To ensure that the needle in the tank indicator does not vibrate due to the quick wave-like movements in the fuel level, the movement of the needle in the display instrument is damped.
Other manufacturers do not damp the needle, but rather the fluid-level sensor itself is fitted with a damping device that offsets the quick movements in the fuel level. These damped fluid-level sensors are difficult to move. They must never be moved forcefully, or they will bend or break.
