摘要

The plastic fuel tank primarily for motor vehicles comprises tank main structure (1) consisting of inner and outer shells (3, 4) and an interposed permeation barrier layer (2), and auxiliary component (6) provided with a permeation barrier layer (8). The latter is tightly joined to the barrier layer (2) which is exposed in the surface of the hole (5) serving as a seating for the auxiliary component.
