A filling level indicator for determining a filling level in a tank, having a resistor network, a contact element, and a magnetic element. The contact element is spaced apart from the resistor network and the magnetic element is movable relative to the resistor network and the contact element. The contact element has a contact region deflectable by the magnetic element. An electrically conductive connection between the contact region and the resistor network is produced by deflection of the contact region. The contact region is formed by a planar tape-shaped element and the contact region has contact portions that are spaced apart from one another in the circumferential direction. The contact portions are separated from one another by separation regions.

A tank valve system comprises a main valve body, an overfill protection device (OPD), a gauge drive apparatus and a fuel level indicator. The OPD and gauge drive apparatus are configured to both be inserted through a narrow neck of a fuel storage tank prior to connecting the valve body to the neck. The valve body includes a primary fuel channel and a shuttle interface channel. The OPD includes an overfill float driving an overfill shutoff valve for controlling fluid flow from the primary channel into the tank. The gauge drive apparatus includes a gauge float, a shuttle, and an elongated extension body. The gauge float is movable with respect to the extension body between an uppermost position and a lowermost position, thereby driving the shuttle. The shuttle has a gauge actuation portion transportable within the shuttle interface channel to thereby actuate the fuel level indicator.
