Installing a fuel line is a task that's best left to an expert. Fuel lines can be made of rubber, metal or plastic material, and their job is to deliver fuel from the tank to the engine. Fuel can be flammable, and handling it incorrectly can be dangerous.
A certified automotive technician should be the one diagnosing fuel problems in a car. It follows that he should be the one doing the repairs as well. However, with the right know-how, experience and tools, it is possible to perform fuel replacement on your own, the biggest advantage of which is that you can earn significant savings on labor costs. Signs of a fuel line problem include the constant smell of gasoline around the car and wet puddles on the pavement underneath the vehicle.
