A fuel tank for a motor vehicle comprising a wall composed of two shells arranged one above the other. The outer shell of the wall preferably has an inlet orifice and an outlet orifice. A filter element is arranged in front of the outlet orifice. Scavenging air from the inlet orifice thereby passes first into a gap between the shells and subsequently to a filter element. As a result, fuel vapors can no longer diffuse through the wall and pollute the environment.

Fuel tank

A fuel tank for a motor vehicle, having a wall ( ) which is manufactured from plastic, in particular by injection molding, is provided on its inside with a permeation barrier ( ). The permeation barrier ( ) is manufactured from a material which is virtually impenetrable for fuel vapors. The permeation barrier ( ) is composed of shell parts ( ) which are welded to one another.

Fuel tank for a motor vehicle

In a method of producing a fuel tank from plastic, a heating element is located between two shell parts to be welded to one another. When the shell parts are pressed together, the heating element melts into the plastic and produces a weld that provides a fuel-resistant seal. The fuel tank subsequently has a particularly exact shape.

Method of producing a plastic component and fuel tank for a motor vehicle

A device for supplying an internal combustion engine (,) of a motor vehicle with fuel has a return line (,) which is passed into a fuel tank (,) and has a wall made of a material of high thermal conductivity. The return line (,) is arranged within a ventilation duct (,). Cooling air is conveyed through the ventilation duct (,) to the return line (,). This is a simple means of limiting the maximum temperature of the fuel in the fuel tank (,).
