Absolutely agree "it should" but I would ask. Then why did the engineers find the need to fabricate the grounding device attached on each side of the rubber hose @ the metal fuel line. Contact should be complete some where in the mix with the tank straps to the body more efficiently than the flange ring. Heck just through the flow of fuel in the line should make a complete circuit. But then I just pulled a 16hr run again and no sleep maybe I'm missing something. I can learn.
