Fuel lines are an essential safety feature of every car. They are usually made from reinforced rubber, but can also be made from other materials such as steel, aluminium, copper, or plastic. The type of material used is important as it must be able to withstand normal vehicle vibrations and chemical reactions with gasoline.
| Characteristics | Values |
|---|---|
| Material | Metal fuel lines are made from steel or aluminium, while rubber fuel lines are made from reinforced rubber or other elastomeric materials. Braided fuel lines are made from a metal or synthetic fibre braid wrapped around a rubber or elastomeric core. PTFE-lined fuel lines have an inner layer of PTFE (polytetrafluoroethylene) coated with a layer of braided stainless steel or other metal. Older models used copper, while modern vehicles often use plastic, typically nylon. |
| Durability | Metal fuel lines are more durable than rubber or braided fuel lines as they are resistant to wear and tear and are not prone to cracking or deterioration. |
| Safety | Fuel lines that connect to the body, frame, or engine are made of seamless steel tubing. The steel spring also wraps around the pipe at certain points to prevent damage. |

What You'll Learn
Metal fuel lines are made from steel or aluminium
Aluminium is another metal used for car fuel lines. It is a durable material that is resistant to wear and tear. It is also lightweight, which can make it easier to work with when manufacturing or repairing cars.
Copper was also once used for fuel lines, but this is now considered outdated as it cannot handle normal vehicle vibrations or chemically react with gasoline. Modern vehicles often use plastic, typically nylon, for their fuel lines. This is a more flexible option than metal, but it can perish over time and rub through if not properly secured.

Rubber fuel lines are made from rubber or elastomeric materials
Braided fuel lines are typically made from a metal or synthetic fibre braid that is wrapped around a rubber or other elastomeric core. PTFE-lined fuel lines have an inner layer of PTFE (polytetrafluoroethylene), a synthetic fluoropolymer, which is coated with a layer of braided stainless steel or other metal. Metal fuel lines are generally more durable than rubber or braided fuel lines, as they are resistant to wear and tear and are not prone to cracking or deterioration.
In older models, the fuel line hoses were equipped with copper material. The advantage of using copper hoses is that they are easy to install and service, but they are bulky and expensive compared to other materials. Modern types of vehicles often use fuel lines made of plastic, usually nylon.

Braided fuel lines are made from a metal or synthetic fibre braid
Fuel lines are a safety feature of every car and must comply with safety regulations. Most fuel lines that connect to the body, frame, or engine are made of seamless steel tubing. The steel spring also wraps around the pipe at certain points to prevent damage.
Braided fuel lines are typically made from a metal or synthetic fibre braid that is wrapped around a rubber or other elastomeric core. The metal used in braided fuel lines is often stainless steel. Braided fuel lines are more durable than rubber fuel lines as they are resistant to wear and tear and are not prone to cracking or deterioration.
Rubber fuel lines are made from rubber or other elastomeric materials. They are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured.
More modern vehicles may be fitted with fuel lines made of plastic, typically nylon. Copper fuel lines were used in older models of cars.

PTFE-lined fuel lines are coated with braided stainless steel
Fuel lines are a safety feature of every car and must comply with safety regulations. Most fuel lines that connect to the body, frame, or engine are made of seamless steel tubing. The steel spring also wraps around the pipe at certain points to prevent damage. Whenever a fuel line is replaced, only steel tubing should be used.
Rubber fuel lines are also common. They are made from rubber or other elastomeric materials. Rubber hoses are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured. To prevent breakage and kinking, fuel lines are usually made of reinforced rubber. More modern vehicles may be fitted with fuel lines made of plastic, typically nylon.
