Problem overview

Some Chevrolet Cobalt owners report experiencing fuel pump issues related to rusted housing and fuel leakage, including rusting metal fuel lines that lead to fuel leaks. Additionally, there are reports of leaking fuel pumps located at the top of the fuel tank, which can cause fuel to run down in front of the charcoal canister. Some owners have also noted leaks from the gasket connecting the filler hose to the gas tank, raising concerns about potential fuel leaks. In response to these issues, General Motors has issued a product safety recall for fuel leaks on the Chevy Cobalt, offering to install a new design fuel pump module assembly free of charge. If you suspect a fuel pump issue in your Chevrolet Cobalt, it is important to seek professional assistance to address the problem promptly and effectively.
