Fuel lines can be made from a variety of materials, including metal, rubber, and copper-nickel tubing. Metal is the best material for fuel lines, but it can be difficult to fabricate. Metal lines are usually made from stainless steel, aluminium, or coated steel tube. Stainless steel is the best option for hardline fuel lines, although it can be hard to bend without cracking. For flexible hose, Gates Barricade makes a fuel line hose suitable for carbs and EFI that was designed to work with alcohol fuels.

What You'll Learn
Metal is the best material for fuel lines
While rubber fuel lines are easy to install, they are not as strong as metal. Copper-nickel tubing is also an option, as it is easily bent and does not work harden and crack like copper. However, copper is prone to fatigue cracking and is not suitable for use in cars. Stainless steel is a good option for hardline fuel lines as it is strong and durable, but it can be difficult to bend without cracking.
If you are looking for a flexible hose, Gates Barricade makes a fuel line hose that is suitable for carbs and EFI and was designed to work with alcohol fuels. For a soft fuel line, metal braided teflon is a good option.

Stainless steel is the best option for hardline
Fuel lines can be made from many different materials, but metal is the best material for fuel lines. Metal lines hold up better than any soft material and are usually made from stainless steel, aluminium or coated steel tube.
For hardline, stainless steel is still the best option. It is hard to bend without cracking, but it is a more durable material than copper, which is very prone to fatigue cracking. Copper-nickel tubing is also an option, as it is easily bent and does not work harden and crack like copper. However, stainless steel is the best option for hardline as it is the most durable material.

Copper is prone to fatigue cracking
For hard fuel lines, stainless steel is the best option. It is a hard metal that is difficult to bend without cracking, making it a durable choice for fuel lines. Metal fuel lines are generally preferred over soft materials as they hold up better. Other metals that can be used for fuel lines include aluminium and coated steel tube.
When it comes to soft fuel lines, rubber fuel hose is a popular choice as it is easy to install. However, some racing classes may restrict the amount of rubber line allowed, so it is important to check the rules before choosing this option. Metal braided Teflon is another soft fuel line option that can be considered.
In summary, while copper is prone to fatigue cracking and not suitable for fuel lines, there are a variety of other materials that can be used, including stainless steel, aluminium, coated steel tube, rubber, and metal braided Teflon. The best material for a fuel line will depend on the specific requirements and restrictions of the vehicle and any applicable racing regulations.

Cloth-covered neoprene is an option for vintage cars
Metal is the best material for fuel lines. Metal fuel lines are usually made from stainless steel, aluminium or coated steel tube. Metal is hard to fabricate, but it holds up better than any soft material.
Rubber fuel hose is easy to install, but some racing classes won't allow more than 12 inches of total rubber line. Copper should also be avoided as it is prone to fatigue cracking.

Frequently asked questions
Fuel lines can be made from a variety of materials, including stainless steel, aluminium, coated steel tube, rubber, copper-nickel tubing, cloth-covered neoprene, and metal braided teflon.
Stainless steel is the best option for a hard fuel line. It is strong and durable, but can be difficult to bend without cracking.
For a flexible fuel line, Gates Barricade is a good option. It is designed to work with alcohol fuels and is suitable for carbs and EFI.
Copper is not recommended for fuel lines as it is prone to fatigue cracking. Copper-nickel tubing, on the other hand, is a suitable option as it is easily bent and does not work harden and crack like copper.
The size of the fuel line depends on the application. For a stock application, a 3/8" fuel line is usually sufficient.
