The invention relates to a fuel tank having two tank parts which are connected to each other. Allocated to one tank part is an accumulation vessel and to the other tank part is a fuel distributor which is connected to a fuel return line. Two feed lines which convey fuel into the accumulation vessel are connected to the distributor. Integrated into one feed line is an ejector which is provided in the bottom region of the tank space having the distributor. Interposed in the other feed line is an ejector which is provided in the tank part having the accumulation vessel. For the purpose of being able to connect the feed lines to the fuel distributor and accumulation vessel quickly and easily, the fuel tank has a respective tank opening which can be tightly closed by them. The flexibly constructed feed lines are to be installed in the tank with an excess length which makes it possible to pull their line end pieces out of the tank openings and, outside the fuel tank, to connect them to the accumulation vessel and the distributor respectively.

A blanking cover for the filler neck of a motor vehicle fuel tank has a grip protruding from the blanking cover body so as to ensure that reliable filler neck sealing is maintained in the case of a crash when a collision occurs between the grip and a body part. The grip can be released from the blanking cover body under the action of crash forces.

A fuel lock as part of a venting arrangement for fuel tanks has to ensure that when the fuel tank is on its side, particularly after a lateral rotation of 270.degree., only a legally tolerated fuel quantity can flow out from the vent conduit. The fuel lock has an inlet chamber and an outlet chamber separated from the former by a partition and communicating with its chamber by a connecting conduit. The inlet chamber is connected to a surge tank of the fuel tank by an inlet conduit and the outlet chamber is connected to a vent conduit. In the inlet chamber, the inlet conduit and connecting conduit mouthpiece openings within the chamber and, in the outlet chamber, the connecting conduit and outlet conduit mouthpiece openings within the chamber are located relative to one another such that in the syphon conduit formed by these conduits and passing through the chambers, in each case a break point for the syphon effect is present within the chambers. The inlet conduit mouthpiece opening within the inlet chamber is located above the maximum fuel level in the tank installation attitude and in an attitude when the tank is on its side. The volume of the outlet chamber is larger than that of the inlet chamber and preferably corresponds to at least twice the volume of the outlet conduit.

A fuel tank having two tank spaces spaced from one another and connected to one another at a distance above their bottom. One tank space is equipped at its bottom with a retaining vessel having a closed shell. To assure that both tank spaces are reliably emptied, each tank space is equipped with a jet pump charged with fuel via a supply line. Both of the jet pumps, which are parallel or series connected to each other, deliver fuel to the retaining vessel.
