Fuel lines are not made to last forever. In this video, we take a close look at the Volkswagen Jetta fuel line setup and see how it’s different from other cars. Some models leave the lines exposed, while Volkswagen protects them with high-strength steel channels. We’ll also talk about why fuel lines have a service life, what risks come with worn or exposed lines, and when they should be replaced. Volkswagen recommends changing them every fifteen years or at two hundred forty thousand kilometers.
