INTERFACE WELD SEAL FOR LOW PERMEATION FLANGE OF A FUEL SUPPLY UNIT

摘要

A flange structure (10') for a fuel supply unit of a vehicle includes at least one electrically conductive fuel port (16') having first and second ends (22, 24). A plastic flange (20') is overmolded on at least a portion of the fuel port between the first and second ends. The flange is constructed and arranged to be coupled with a fuel tank of a vehicle. A welded connection (26) is provided between the fuel port and the plastic flange defining a barrier to prevent fuel or fuel vapor from passing between the periphery of the fuel port and the flange.
