Fuel leaking from fuel line near front of gas tank. Upon inspection, fuel line was rotted through. Further inspection by mechanic found fuel and vapor return lines were all corroded and needed to be replaced. A leaking fuel line could cause a fire. All brake lines were replaced two years ago due to corrosion and failure of a brake line while driving due to the corrosion. Chevy dealer refused to repair the broken line, insisting that all brake lines must be replaced due to the corrosion. Rear brake shields have also rotted away, and the differential cover is also rotting. These will also require replacement. None of the corroded parts described here have any kind of coatings to prevent corrosion. Brake and fuel line corrosion are common problems on this model and year, and Chevrolet or NHTSA do not appear to be able or willing to do anything about it.
