A dual reservoir fuel tank, wherein the fuel tank comprises a main fuel reservoir having an inner wall and an outer wall that define a main reservoir chamber, and an auxiliary fuel reservoir connected to a bottom of the main fuel reservoir. The dual reservoir fuel tank additionally includes a fuel retention lip structured and operable to retain fuel within the auxiliary reservoir chamber when the dual reservoir fuel tank is disposed at an angle.

A system of fuel delivery assemblies is provided. In one example, the system includes two separate fuel pump assemblies each having a reservoir with an interior to receive fuel. Each reservoir has at least one dimension that is different than the other reservoir. A housing is adapted to be separately coupled to each of the reservoirs so that a cartridge may be separately used with both fuel pump assemblies. The cartridge orients at least one fuel system component relative to the reservoir to which the reservoir is connected.

The present disclosure relates to a plastic tank, particularly a plastic fuel tank, with a pot-like installation body arranged on the inside of the tank, as well as a method for producing the same. According to the present disclosure, a ring body is provided which is arranged on an end portion of the installation body (24), wherein the ring body is engaged in an undercut section in the tank wall, and the installation body is engaged in the ring body.

A fluid-conveying device for conveying a fluid from a tank includes: a first fluid-conveying pump; a swirl pot; and a second fluid-conveying pump having a drive region and a conveying region coupled to the drive region. The fluid is conveyable from the swirl pot by the first fluid-conveying pump, and the conveying region is configured and arranged so as to be drivable by the drive region.

A tank system for a construction machine includes a fuel tank having an outer tank wall that closes off a tank volume to the outside, a withdrawal tank volume, which is separated by a partition wall from a main tank volume of the tank volume and has a fuel-exchanging connection to the main tank volume, and a fuel withdrawal arrangement having a main fuel pump and a withdrawal line opening into the withdrawal tank volume for conveying fuel by the main fuel pump via the withdrawal line from the withdrawal tank volume to a fuel-consuming system region. The tank system also includes a fuel feed arrangement having an auxiliary fuel pump for conveying fuel from the main tank volume into the withdrawal tank volume.

A fuel conveying device having a pumping stage, an electric motor to drive the pumping stage, a control unit, a magnetoresistive fill level sensor that generates a fill level signal, including a temperature-effect compensator that generates a compensation signal to compensate for temperature-related influences on the fill level signal, and an evaluation unit (5) designed such that the temperature of a fluid surrounding the fill level sensor can be determined by the evaluation unit by the compensation signal. A fuel tank equipped with a fuel delivery device of said type, a method for determining the temperature of a fluid inside a fuel tank, a method for controlling and/or regulating an electric motor, and a method for controlling and/or regulating an injection of fuel vapors to a combustion process of an internal combustion engine.

The invention related to a vehicle suction system comprising a compartment (200) for storing an aqueous liquid (L); and a suction line (20) arranged for sucking the aqueous liquid out of the compartment (200); said suction line (20) comprising at least one suction branch and the at least one suction branch being provided with at least two suction orifices (10a, 10b, 10c, 10d) positioned at different positions in the compartment (200); wherein at least one suction orifice is provided with a blocking means (40) configured for blocking at least a part of said suction orifice when the suction orifice is not in the aqueous liquid and for allowing the aqueous liquid to be sucked through the suction orifice when the suction orifice is in the aqueous liquid.
