The present invention discloses a dual mode fuel tank leakage detector (100), comprising of an electromechanical valve (1) with a canister port, an engine control unit, pump assembly, a sensor (3) and works in pressure condition by comparing a measured pressure with reference pressure; in case there is leakage then the pressure is not upto the reference pressure within time interval. In case of no leakage, the pressure will be equal/above than the reference pressure, the leakage detector (100) works in vacuum condition by comparing a measured leakage with a reference leakage, in case there is a leakage the measured vacuum is not able to reach to the reference vacuum within a time interval and when there is no leakage, the measured vacuum will be equal or above from the reference vacuum and fuel tank leakage detector (100) enables to monitor leakage detection either in vacuum or pressure conditions.
