Abstract
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.
