A fuel pump module for installation between top and bottom walls of a fuel tank. The housing defines a space accommodating a pump. The fuel pump module includes a mounting component coupled to the housing. The mounting component includes a first surface, a second surface opposite the first surface and facing the housing, a first end, and a second end opposite the first end. The mounting component and the housing are joined with a spring-loaded coupling such that the mounting component is urged away from the housing. The mounting component further includes a U-shaped recess that is concave on the first side of the mounting component. The bottom side of the housing forms a first distal end of the fuel pump module for engaging the bottom wall. The first surface of the mounting component forms a second distal end of the fuel pump module for engaging the top wall.

A fuel supply system for a vehicle having an internal combustion engine and a fuel tank, has a reservoir, a fuel pump, a suction filter, a fuel transfer and a pressure accumulator. The reservoir is located in the fuel tank and is hermetically sealed. The fuel pump is configured to suck fuel from the reservoir and to supply the fuel to the internal combustion engine. The suction filter is configured to filter the fuel sucked by the fuel pump. The fuel transfer is configured to transfer the fuel from the fuel tank into the reservoir and to pressurize the fuel in the reservoir. The pressure accumulator is connected to the reservoir in order to control a pressure of the fuel in the reservoir.

A fuel delivery module for a vehicle having a fuel tank. The fuel delivery module comprises a flange, a reservoir, a fuel pump, a guide rod, a guide rod receiver, and an elastically deformable member. The flange couples to an opening of the fuel tank. The reservoir is in fluid communication with the flange and a fuel pump connected to the reservoir transports fuel from inside the fuel tank to outside the fuel tank through the flange. The guide rod is coupled to the flange at a first end of the guide rod and the guide rod receiver is fixedly disposed on the reservoir. The elastically deformable member is moveably coupled to the guide rod and to the reservoir such that a second end of the guide rod is selectively receivable in the guide rod receiver.

A sensor device 1 includes a fuel property sensor 5 configured capable of detecting a property of fuel that is ejected from a fuel pump 4 in a feel tank 2; a guiding line 12 configured to guide fuel ejected from the fuel pump 4 to the fuel property sensor 5; and a relief valve 21 configured to allow fuel to flow out of the guiding line 12 when a pressure of fuel in the guiding 12 becomes equal to or higher than a predetermined pressure.

An operating medium vessel for a vehicle is provided for storing liquid operating medium and has: a withdrawal section with a reservoir pot arranged therein; a feed section which is connected fluid-conductively to the withdrawal section and is adjacent to the withdrawal section; and an operating medium delivery system with an operating medium reservoir arranged in the feed section, and with a first delivery device and a second delivery device. The first and the second delivery devices are each fluid-conductively connected to the operating medium reservoir. The first delivery device is designed to deliver operating medium out of the feed section from outside the operating medium reservoir into the operating medium reservoir, and the second delivery device is designed to deliver operating medium from the operating medium reservoir into the reservoir pot.
