Abstract: A vehicle component for a motor vehicle includes a coupling device including two couplable coupling elements configured to provide, in a coupled state, a fuel-tight connection of two fuel-conducting lines. One of the coupling elements is in a form of a metallic female element which is fixedly connectable to one of the two lines, and an other one of the coupling elements is in a form of a metallic male element which is fixedly connectable to an other one of the two lines. The male element, for coupling purposes, is insertable into the female element, wherein, in the coupled state, an axially extending overlap section with at least one radial seal device is formed between the female element and the male element. A securing device is configured to secure the coupling elements in the coupled state against inadvertent release from one another.

Abstract: A pipe connector is for connecting a fuel line of a fuel supply for a motor vehicle engine of a motor vehicle. The pipe connector has a coupling element that includes a metallic material and is configured to connect to the fuel line, where the fuel line includes a synthetic material. The coupling element includes a pipe projection configured for clamping insertion into the fuel line and a retaining collar for radially externally surrounding the fuel line. An extent of the retaining collar in an axial direction and a distance between the retaining collar and pipe projection is selected so as to limit swelling of the fuel line.

Abstract: A method for determining a buffer effect of an activated carbon filter for a tank venting system of a fuel container for hydrocarbon-containing fuels involves feeding a defined quantity of hydrocarbon molecules to the activated carbon filter (320) via a tank connection (320_1) of the activated carbon filter (320) by a hydrocarbon feed system (310). A carrier gas flow is introduced into the activated carbon filter (320) via an air connection (320_2) of the activated carbon filter (320), and a defined volumetric flow is sucked out of the activated carbon filter (320) via an engine connection (320_3) of the activated carbon filter (320) by a hydrocarbon measuring device (340), and its content of hydrocarbon molecules is measured. The defined quantity of hydrocarbon molecules is made available by the hydrocarbon feed system (310) in the form of a thermodynamically isolated gas quantity.
