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.

Device for delivering fuel out of a fuel tank

In a fuel tank (), a condensate collector () of a venting line () with a closure lid () forms one structural unit. The closure lid () closes off an opening () in a wall () in the fuel tank (). The condensate collector () has spring elements () for prestressing elastic venting lines () against the inside of the fuel tank () and the venting device () can be mounted through the opening () in the fuel tank ().

Fuel tank for a motor vehicle

A fuel tank () has a constructional unit which can be preassembled and comprises a surge chamber () and venting device (). The constructional unit is fastened to the bottom of the fuel tank () and has spring arms for prestressing openings (), which are provided for venting the fuel tank (), against the upper wall of the fuel tank (). The fuel tank () can be fitted in a particularly simple manner.

Fuel tank

In a venting device for a fuel tank (), a venting line () has a movable section () and a spring element (). The free end of the venting line () is prestressed against an upper wall of the fuel tank (). This ensures that a valve () which is arranged at the free end of the venting line () is always arranged in the vicinity of the upper wall of the fuel tank ().
