A motor vehicle tank that includes a tank container formed by a tank wall, and a holding element to fasten a component to the tank wall at an interior of the tank container. The holding element has at least one attachment point for fastening the holding element to the tank wall, at least one fastening element for fastening the component to the holding element, and a plurality of spring elements arranged between the at least one attachment point and the fastening element to facilitate fastening of the component to the tank wall in a spring-elastically decoupled manner.

A fuel system for an aircraft is provided including a fuel tank configured to receive fuel and a fuel pump. The fuel pump includes a motor disposed proximate the fuel tank. The fuel pump further includes a power supply in electrical communication with the motor and disposed outside the fuel tank. The fuel pump further includes an impeller disposed within the fuel tank and rotatably coupled to the motor. The impeller includes a shaft having a first end and a second end spaced from the first end with the motor coupled to the first end. The shaft has a resistivity greater than the resistivity of the fuel tank between the first end and the second end to minimize electrical transfer between the motor and the fuel.
