Fuel lines are called hoses or pipes and are used to transfer fuel from one point to another or from a storage tank to a vehicle. Fuel lines can be made from a variety of materials, including metal, rubber, plastic, copper, and aluminium. Metal is the best material for fuel lines, but it can be difficult to fabricate. Rubber fuel hoses are easy to install, while plastic fuel pipes are lighter than metal pipes and do not rust.

What You'll Learn
- Fuel lines are usually made from reinforced rubber
- Seamless steel tubing is used for fuel lines that connect to the body, frame or engine
- Copper and aluminium pipes should not be used to replace steel pipes
- Rigid fuel lines are secured with the frame from the fuel tank to a location near the fuel pump
- Modern vehicles use fuel lines made from plastic, usually nylon

Fuel lines are usually made from reinforced rubber
In older models, the fuel line hoses were made from copper. Copper is easy to install and service, but it is bulky and expensive compared to other materials. Modern vehicles often use fuel lines made of plastic, usually nylon. Plastic fuel pipes do not rust and are lighter than metal pipes, but they melt at low temperatures and are not easy to repair.
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, use only steel tubing. Connections between steel fuel lines and other components of the system are often made with short hose sections.

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. Copper and aluminium pipes should not replace steel pipes. These materials cannot handle normal vehicle vibrations or chemically react with gasoline.

Plastic fuel pipes do not rust and are lighter than metal pipes, but they melt at low temperatures and are not easy to repair. Metal is the best material for fuel lines. However, it can be difficult to fabricate. Rubber fuel hose is easy to install and is used in most fuel systems where flexibility is needed.

Copper and aluminium pipes should not be used to replace steel pipes
Fuel lines are called hoses or pipes and are used to transfer fuel from one point to another or from a storage tank to the vehicle. They are usually made from reinforced rubber to prevent breakage and kinking. Metal is the best material for fuel lines, but it can be difficult to fabricate.

Synthetic rubber hoses are used in most fuel systems where flexibility is needed. Connections between steel fuel lines and other components of the system are often made with short hose sections. The inside diameter of fuel delivery hose is generally larger (8 to 10 mm) and of the fuel return hose is smaller (6 mm).

Rigid fuel lines are secured with the frame from the fuel tank to a location near the fuel pump
Fuel lines are called hoses or pipes and are used to transfer fuel from one point to another or from a storage tank to the vehicle. Rigid fuel lines are usually made of seamless steel tubing and are secured with the frame from the fuel tank to a location near the fuel pump. The steel spring also wraps around the pipe at certain points to prevent damage. The gap between the frame and the pump is then bridged by a short flexible hose that absorbs engine vibrations.
