There are several different types of automotive fuel lines, including metal, rubber, braided, and PTFE-lined. Metal fuel lines are made from materials such as steel or aluminium, while rubber fuel lines are made from rubber or other elastomeric materials. Braided fuel lines are 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. Each type of fuel line has its own unique characteristics in terms of flexibility, compatibility, cost, and durability.
| Characteristics | Values |
|---|---|
| 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 |
| Material | Metal fuel lines are made from steel or aluminium; rubber fuel lines are made from rubber or other elastomeric materials; braided fuel lines are made from a metal or synthetic fibre braid that is wrapped around a rubber or other elastomeric core |
| Flexibility | Synthetic hoses are used in most fuel systems where flexibility is required |
| Inner diameter | The inner diameter of the oil pipe is generally larger, and the inner diameter of the oil return pipe is smaller |

What You'll Learn
- Metal fuel lines are more durable than rubber or braided fuel lines
- Rubber fuel lines can become hard and brittle over time
- Braided fuel lines are prone to leaks if the braid becomes damaged
- Synthetic hoses are used in most fuel systems where flexibility is required
- Rigid fuel lines are secured with the frame from the fuel tank to a location near the fuel pump
Metal fuel lines are more durable than rubber or braided fuel lines
Metal fuel lines are also used in conjunction with synthetic hoses in fuel systems where flexibility is required. Connections between steel fuel lines and other components of the system typically employ shorter line sections. The inner diameter of the oil pipe is generally larger, and the inner diameter of the oil return pipe is smaller. Metal or plastic restrictors are used in exhaust pipes to control the steam flow rate. They are located at the end of the exhaust pipe or the steam exhaust hose itself.

Rubber fuel lines can become hard and brittle over time
Braided fuel lines, on the other hand, are typically made from a metal or synthetic fibre braid that is wrapped around a rubber or other elastomeric core. While they are more flexible than metal lines, they are not as flexible as rubber lines. Braided lines are also compatible with a wide range of fuels but, like rubber lines, may not be suitable for use with certain chemicals. Additionally, braided lines can be prone to leaks if the braid becomes damaged.
Metal fuel lines are the most durable option, as they are resistant to wear and tear and are not prone to cracking or deterioration. They are generally compatible with all types of fuel. However, metal lines are the most expensive option and are less flexible than rubber or braided lines, which can make them more difficult to install in tight spaces.
PTFE-lined fuel lines are another option, which have an inner layer of PTFE (polytetrafluoroethylene), a synthetic fluoropolymer, coated with a layer of braided stainless steel or other metal. These lines are very durable and resistant to wear, heat, and chemical damage. They are also flexible, although perhaps not as flexible as rubber or braided lines. PTFE-lined lines are generally compatible with a wide range of fuels and chemicals, but they may not be suitable for use with certain fuels or solvents.

Braided fuel lines are prone to leaks if the braid becomes damaged
Braided fuel lines are typically made from a metal or synthetic fibre braid that is wrapped around a rubber or other elastomeric core. They are more flexible than metal lines, but not as flexible as rubber lines. Braided fuel lines are also compatible with a wide range of fuels, but may not be suitable for use with certain chemicals. They are also typically more expensive than rubber or metal fuel lines.
It is important to regularly inspect braided fuel lines for any signs of damage or wear and tear. This includes checking for any cracks, cuts, or abrasions on the braid, as well as any signs of fuel leakage. If any damage is detected, it is important to replace the fuel line as soon as possible to prevent further issues.
To prevent damage to braided fuel lines, it is important to handle them with care during installation and maintenance. This includes using proper tools and techniques to avoid any cuts or abrasions to the braid. It is also important to ensure that the fuel line is properly secured and protected from any potential sources of damage, such as sharp edges or debris.
Overall, while braided fuel lines offer some advantages in terms of flexibility and compatibility, they require careful handling and maintenance to prevent leaks and ensure the safety of the vehicle.

Frequently asked questions
Fuel lines are hoses or pipes that transfer fuel from one point to another, or from a storage tank to a vehicle.
The most popular styles of fuel lines are metal, rubber, braided, and PTFE-lined.
Metal fuel lines are generally compatible with all types of fuel and are more expensive than rubber or braided fuel lines. Rubber fuel lines are typically the least expensive option, but may not be suitable for use with certain fuels or chemicals. Braided fuel lines are more flexible than metal lines, but are not as flexible as rubber lines, and are typically compatible with a wide range of fuels. PTFE-lined fuel lines are very flexible, but may not be as flexible as rubber or braided lines, and are generally compatible with a wide range of fuels and chemicals.
Fuel lines transfer fuel from one point to another, or from a storage tank to a vehicle. Oil lines, on the other hand, transfer oil within the vehicle's engine.
