In a fuel tank installation including a fuel tank with an expansion volume, a filler neck connected to the fuel tank below a maximum fuel level of the tank for refueling the tank, a fill vent line for venting the fuel tank during refueling and an operating vent line for venting an expansion volume of the tank, the operating vent line extends within the fuel tank from the expansion volume of the fuel tank to a central penetration location and, at the central penetration location, through the wall of the tank together with the fill vent line.

Fuel tank installation

In a fuel tank installation including a fuel tank with an expansion volume, a filler neck connected to the fuel tank for refueling, a fill vent line for venting the fuel tank during refueling and an operating vent line for venting the expansion volume of the tank, electrically operable valve means for blocking the operating vent line are arranged in a penetration area of the fuel tank where the operating vent line extends through the fuel tank.

A fuel tank arrangement for a motor vehicle. The arrangement includes a fuel tank containing fuel therein and having a gas space disposed above the fuel, and a venting device connected to the fuel tank. The venting device includes an activated charcoal filter and a venting conduit connecting the gas space to the activated charcoal filter for establishing gas communication therebetween. A stop valve is disposed in the venting conduit and is adapted to open gas communication between the gas space and the activated charcoal filter during refueling. Moreover, a fuel separator is disposed in the venting conduit for separating fuel from a gas flow through the venting conduit thereby yielding separated fuel.
