Abstract

A strategy for decreasing hydrocarbon emissions from a plastic fuel tank assembly having a multilayer plastic fuel tank (,) and at least one overmolded fuel tank attachment (,). The strategy consists of two basic components. First, the swelling properties of the overmolded outerlayer (,) of the fuel tank attachments,are exploited to close possible leakage paths between the barrier resistant core (,) and the overmolded outerlayer (,) of the fuel tank attachment (,). Second, the barrier properties of the barrier resistant core (,) of the fuel tank attachments (,) are exploited to increase the length of the diffusion path of hydrocarbon molecules out of the multilayer plastic fuel tank assembly.
