Abstract
A fuel tank for a motor-vehicle includes a vent conduit connected to a canister arranged outside of the tank for absorbing fuel vapors. The vent conduit has a portion arranged inside the tank with an intermediate portion located at a lowermost position, which creates a zone in which liquid fuel tends to stagnate, which is originated from condensation of the vapors inside the vent conduit. The tank further includes a conduit for draining the liquid fuel originated from condensation of vapors present within the vent conduit. The draining conduit extends downwardly starting from the zone and ends with a closed end portion acting as accumulator and evaporator of the fuel. The closed end portion is arranged at an area which can reach a temperature sufficient for causing evaporation of the condensed fuel and elimination thereof by a flow in an opposite direction through the draining conduit and then through the vent conduit towards the canister.
