Abstract
Provided is a liquid level sensor for a fuel tank including: a case having a filled liquid filled therein and closed; a resistor substrate provided in the case and a wiper contacting the resistor substrate; and a damper provided in the case and absorbing a pressure change of an inner portion of the case. The liquid level sensor for a fuel tank is configured to absorb a pressure change of the inner portion of the case, thereby making it possible to prevent leakage of the filled liquid that may occur due to the pressure change of the inner portion of the case.
