Electrostatic dissipation solution for angled fuel port of a fuel supply unit
A flange structure ( 10 ′) for a fuel supply unit of a vehicle includes at least one non-electrically conductive plastic fuel port ( 16 ′) having first and second ends. A non-electrically conductive plastic flange ( 20 ′) is integral with 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. Electrically conductive grounding structure ( 32 ) is associated with the fuel port and has an elongated portion ( 36 ) extending within the fuel port so as to be exposed to fuel, and an end ( 40 ) connected with the elongated portion. An electrically conductive hose ( 30 ) is coupled with the first end of the fuel port and is in contact with the end of the grounding structure thereby defining a discharge path such that static electricity generated when fuel flows through the fuel port can be dissipated through the discharge path.
