In a fuel tank ( ) with a plug which is to be opened, in particular, during maintenance work, a plugging part ( ) is fastened in a trough-like depression ( ) of the wall of the fuel tank ( ) by means of a nut ( ). The nut ( ) has a thread ( ) intended for tapping into a bead ( ) of the fuel tank ( ). As a result, the fuel tank ( ) can be manufactured particularly cost-effectively from geometrically simple parts.

A filler neck for the introduction of fuel into a fuel tank of a motor vehicle is constructed of at least two interconnected injection-molded half shells, each half shell having outwardly curved regions which form a filler pipe and vent lines. Also, receptacles for valves and filters are integrally formed in the outwardly curved regions.

Filler neck for a fuel tank of a motor vehicle

In the case of a filling pipe for a fuel tank a branching element is arranged in a section of the filling pipe. The flow of the inflowing fuel preferably runs along an outer wall of the filling pipe, so that a subflow is in each case conducted directly to the antisurge tower through a lower cross-sectional area. Larger volume flows, which completely fill the cross section, pass for the most part directly into the fuel tank. By this means, a sufficient basic supply of the antisurge tower is ensured irrespective of the volume flow produced during filling.

In a fuel supply system with a main tank (,), with a splash pot (,), with a pump (,) fed from the splash pot and with connecting lines (,) for the pump, according to the invention the latter is arranged in the main tank (,) outside the splash pot (,) and is connected to the latter via at least one suction line (,) integrally formed fixedly onto an inner wall (,) of the main tank. It is particularly advantageous if that portion of the forward-run line (,) which is to be connected to the pump is also integrally formed fixedly onto the inner wall, because the pump can then be fluidically connected very simply and quickly by being plugged on. As a further option, the electric connection (,) of the pump can also be made in one operation with the fluidic contacting.
