Abstract: Reservoirs for fuel tanks, which can be filled via an opening that can be closed by a closing element, are already known. Such a closing element interacts with a sealing seat and is arranged on a bearing that is located in the region of the opening and is fixed to an edge area of the opening by at least two struts. In prior art, the opening, with the bearing and the struts, is often produced as a single-piece together with the reservoir and the base by injection molding. A disadvantage thereof is that the struts can undergo material shrinkage during production, which leads to a tension of the struts between the edge area of the opening and the bearing. This can lead to an irregular deformation and hence to an uneven sealing seat, so that the closing element does not seal in a tight manner and that the valve has a leak. in the reservoir according to the invention, the sealing of the opening is improved by at least one strut not having a rectilinear form, thus obtaining elastic expansion compensation.

Abstract: Holding elements are known for holding an assembly in a holder, comprising a holding section for engaging behind the assembly and holding members that are provided on the holding section for holding the assembly in the holder. It is disadvantageous that the holding element is comparatively expensive to produce. For example, it is configured very rigidly in the holding direction, which is achieved with a comparatively high amount of material. This results in high production costs. In addition, in the case of very high mechanical loads the detent connection can detach due to torque acting on the detent hooks. The holding element according to the invention is simplified, thereby lowering the production costs. According to the invention, the holding section has a flat configuration viewed in the holding direction, and the holding members are angled in relation to the holding section and configured as elastically resilient holding arms.

Abstract: Fuel delivery modules are already known having a tank flange and having an accumulator pot which is connected to the tank flange by means of at least one guide rod and which is mounted so as to be axially movable along the guide rod, where the guide rod is pressed with one end into a receptacle of the tank flange. It is disadvantageous that the receptacle is expanded over the entire longitudinal extent as the guide rod is pressed in. As a result of tolerance fluctuations in production, excessively high pressures can occur in the receptacle here, which pressures can cause cracks in the receptacle. This leads to rejects and therefore to high production costs. In the fuel delivery module according to the invention, damage to the receptacle during assembly is prevented.

Abstract: Devices for supplying fuel are already known, having a supply unit which has a pump housing connected to an electrical ground and is supported on a pump mount. It is disadvantageous that during operation, the pump mount can become electrostatically charged and has no device for electrostatic discharging during operation. The invention provides an especially simple and economical grounding device for the pump mount. In particular, a charge diverter is connected to the pump housing via a grounding element, and contacts a surface of the pump mount.

Abstract: A fuel supply system is provided for delivering fuel from a tank to an engine of a motor vehicle through a fuel line. The system is provided with a pressure relief valve to divert fuel from the fuel line during engine shut down conditions when fuel flow to the engine is not desired. The pressure relief valve has a fuel outlet that is provided with backpressure during engine operation. The backpressure enables the pressure relief valve to be set at a lower level because the backpressure is added to set point pressure to determine opening of the pressure relief valve. Lowering the set point of the pressure relief valve allows fuel to be diverted from the engine at a lower fuel line pressure. In one embodiment backpressure is provided by fluid communication from a jet pump supplying fuel from the fuel tank to a fuel system reservoir.
