The invention also relates to a method for producing same and using same, and to hollow profiles comprising same.

Liquid fuel tank comprising a plurality of liquid level detection capacitive sensors, each arranged along an edge of the fuel tank such that the capacitance of said sensors varies with the volume of fuel present in the fuel tank, wherein an independent liquid level detection capacitive sensor is arranged along each edge of the fuel tank bottom and of the side walls; wherein the tank is electrically conductive and each level sensor comprises an electrically insulating plate arranged thickness-wise between sensor and tank, such that tank and sensors are capacitively uncoupled. Method for obtaining the fuel volume comprising: obtaining the reading of the liquid level detection capacitive sensors arranged on the edges of the tank; calculating the volume, corresponding to the fuel, of the geometric solid defined by the fuel tank and by the upper surface of the fuel as defined by the liquid level readings from the sensors.

A fuel demand valve that opens with minimal engine suction pressure. The fuel demand valve has an inlet housing and an outlet housing with a valve door in the outlet housing that moves to allow flow through the valve when exposed to a pressure difference sufficient to overcome a spring internal to the outlet housing. The inlet housing includes a shelf, and two gaskets, one large and one small, are disposed between the shelf and the valve door such that they define different surface areas on the valve door. The different surface areas define the amount of force required to be exerted on the valve door for fuel to flow when exposed to fuel supply and engine suction pressures. The different surface areas provide a mechanical advantage whereby lower suction pressure from the engine exerts the same force as a higher fuel supply pressure on the valve door enabling lower fuel pressure operation.

A multipoint fuel injection system comprises an injection system segment including a circumferentially extending outer support defining a fuel manifold with a plurality of manifold passages extending circumferentially therethrough. A first connector is included at a first circumferential end of the outer support and a second connector is included at a second circumferential end of the outer support opposite the first circumferential end. The first and second connectors are each configured to connect each manifold passage with a manifold passages of a respective outer support of a circumferentially adjacent injection system segment. The system includes a circumferentially extending inner support and a plurality of circumferentially spaced apart feed arms extending radially between the inner support and the outer support. A plurality of outlet openings extend in an axial direction from each feed arm for feeding respective injection nozzles.

In at least some implementations, a device includes a fuel system component having a body through which fuel flows, and a retention member body connected to the body of the fuel system component, the retention member body having one or more retainers that are flexible and resilient, and that extend outwardly from the retention member body and that are arranged to engaged spaced apart portions of an interior of a fuel tank to retain the position in the fuel tank of the fuel system component.

The present disclosure relates to a fuel pump module, and more particularly, to a fuel pump module including a flange module and a reservoir module, in which when a fuel delivery pipe for supplying filtered fuel from the reservoir module to the flange module is coupled to the reservoir module, since the fuel deliver pipe may be coupled to the reservoir module to a desired position in an axial direction and to be prevented from rotating in an axial direction, the fuel delivery pipe may be prevented from interfering with a guide rod connecting the flange module and the reservoir module in a vertical direction, thereby not only preventing the occurrence of fire, but also increasing a common use rate of the reservoir module.

The invention relates to an inlet structure of a reservoir pot, comprising a base plate, which can be arranged in an operating medium tank with the formation of a receiving volume below the base plate, and a plurality of first elements which extend from the base plate, wherein the first elements are at least partially spaced apart from one another, and operating medium can flow between the first elements into the receiving volume and can flow out of the receiving volume, wherein the first elements present a greater flow resistance in the outflow direction than in the inflow direction.

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.
