Abstract
A fuel tank for a combustion engine includes measuring and signal generating devices constructed to measure a filling level or filling volume within the fuel tank, and to transmit a first signal corresponding to the filling level or filling volume to a fuel indicator; a signal modifying device constructed to modify the first signal when the fuel tank undergoes a deformation; and an activator activating the signal modifying device when a valve between an activated carbon filter communicating with the fuel tank and an intake tract of the combustion engine assumes an open position.
