The stock fuel tank in your 1965 Mustang is typically made of unpainted metal, meaning it’s prone to corrosion. If your 1965 Mustang's fuel tank is suffering from rust damage, we offer direct replacement options in steel or stainless steel so you can replace your rusted out tank. Each fuel tank includes all the necessary mounting hardware, gaskets, and drain plugs. Be sure to check out our high-capacity tanks for performance applications and longer weekend cruises.
