Abstract
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.
