A passenger motor vehicle () has a passenger compartment () and a fuel tank module () is in the passenger compartment (). The module () has first and second chambers (). The first chamber () holds a tank bladder and a catch tank () is arranged within the tank bladder. The second chamber () holds a fuel pump unit (). The module () is sealed off from remaining areas of the passenger compartment (), and fuel lines to the module () and from the module () to the internal combustion engine are arranged outside the passenger compartment (). Thus, a high level of safety for the vehicle occupant is ensured despite the accommodation of the fuel module in the passenger compartment, and substantially complete emptying of the fuel in the fuel module is possible.

The end-side holding device for a vent pipe of a fuel tank on a stationary wall of a motor vehicle is constructed in two parts and is composed of a connecting piece connected with the vent pipe and of a counterpart. The end region of the connecting piece, which faces away from the vent pipe, and the counterpart extend from opposite sides of the wall in the area of the recess and are pushed into one another until they interact by way of a releasable detent connection.
