The '68-'82 Corvette was the longest-running generation in this two-seater's 60-year history. Though the car's appearance evolved in that period to remain current, many of its basic mechanical features, including the fuel system, didn't change much at all. In fact, the 20-gallon fuel tank and line were virtually the same from 1963 to 1974, with the exception being a midyear change in the '69 model, from a non-vented tank to a vented one. There were then various changes to the filler and tank from 1975 on, to handle the federally mandated evaporative-emissions equipment.
We recently had the opportunity to follow the installation of a replacement tank (and supporting hardware) in a big-block '69 model. What follows is an overview of that job, performed by the resto pros at California Muscle Cars in Acton.
