I stepped back and reassesed the situation and the $$$ paid out for these parts and dialed my supplier and laid out the facts. I'm awaiting UPS with a shipment of a new sending unit & gauge. The aftermkt supplier is replacing my grief with 'new in box' parts. Perish the thought, but it was 'new in box' parts that got me into trouble at the git go. Has anyone invented quality control yet?
