Abstract
A device for delivering fuel has a fuel delivery unit placed inside a fuel tank and which consists of a swirl pot with a fuel pump situated therein for delivering fuel out via a flow line to an internal combustion engine, and with a ventilation system located inside the fuel tank and serves to withdraw fuel vapors from the fuel tank. This ventilation system consists of ventilation lines and a liquid trap for precipitating fuel. The ventilation lines are arranged with one end in the upper area of the fuel tank, and, with the other end, lead into the liquid trap. An activated charcoal filter located downstream from the liquid trap has a connection to the atmosphere. The liquid trap and the activated charcoal filter are situated next and at the height of the swirl pot. At least the liquid trap is mechanically connected to the swirl pot.
