UNDER THE STRAW HAT – Restorer’s Insight Starting in 1978, GM introduced a bladder-lined fuel tank for safety compliance. Over time, the inner bladder often collapsed or deteriorated, causing severe fuel delivery issues. This bladderless reproduction tank offers a long-term fix with factory-correct capacity and mounting points.
