Claim Text:
1. Fuel tank for a motor vehicle, wherein a vent conduit is provided which is connected to a canister for the absorption of fuel vapors, the canister being arranged outside the tank, wherein said vent conduit has a part inside the tank with an intermediate portion located at a lowermost position, which creates a zone in which liquid fuel originated from condensation of the vapors present in the vent conduit tends to stagnate, wherein said tank further comprises a conduit for draining said liquid fuel, in that the draining conduit extends downwards from said zone and ends with a closed end portion acting as an accumulator and evaporator of the liquid fuel originated from condensation of the vapors, said closed end portion being placed at an area which reaches a temperature sufficient to cause re-evaporation of the condensed fuel, and elimination thereof by reverse flow of the re-evaporated fuel through the draining conduit and then through the vent conduit, in the direction towards the canister.
