A vehicle fuel tank assembly comprising a tank 11 for storing fuel 14, a sensor device 13 disposed inside the tank. The sensor device is integrated with a component 12 of the tank, the sensor device is configured to detect the presence of a plurality of different chemical and/or biological entities in fuel stored in the tank. The plurality of different chemical and/or biological entities being suitable for use in determining whether at least two different types of contaminant are present. The component may be located at a lowest point of the fuel tank. The sensor device may comprise a number of sub sensors (131a-131g, figure 3), each being configured to detect a different biological or chemical entity. The sensor device may comprise a communications interface configured to receive detection information from the sub-sensors, and to transmit the received detection information to a remote processing device located outside the fuel tank. The sensor device may be a lab on chip device which may be based on microfluidic technology. The fuel tank assembly may be an aircraft fuel tank assembly.
