Steel brake lines are commonly used as fuel lines, especially for vintage cars. Steel is affordable, durable, and readily available. However, steel is also challenging to bend and susceptible to rust. To overcome these issues, some steel brake lines are coated with a plastic coating like Polyvinyl Fluoride (PVF) or galvanized to prevent corrosion and rust. When used as fuel lines, steel brake lines must be of sufficient diameter (5/16 or 3/8) to withstand high pressure. While steel brake lines can be used as fuel lines, it is important to consider the challenges of bending and the potential for rust and take appropriate precautions.

Steel brake lines are more affordable, durable, and accessible than aluminium
Steel brake lines are a more affordable, durable, and accessible option than aluminium. Steel brake lines are widely available and can be purchased at a low cost, making them a popular choice for those on a budget. Their affordability is further enhanced by their durability, as steel brake lines are known for their strength and ability to withstand high pressure. With brake systems experiencing significantly higher pressure than fuel systems, steel brake lines are more than capable of handling the pressure requirements of fuel lines.
One of the key advantages of steel brake lines is their ease of use. They are easy to form, bend, and flare without fracturing or splitting. This makes installation and maintenance more accessible and cost-effective, especially for those with limited experience or resources. Steel brake lines are also less susceptible to corrosion than aluminium, ensuring their longevity and reducing the need for frequent replacements.
In terms of accessibility, steel brake lines are readily available from auto parts stores and suppliers. They are a common choice for brake and fuel line applications, ensuring their widespread availability and convenience. On the other hand, some users have reported difficulties in finding aluminium fuel lines, with auto parts chains and speed shops often not carrying them. This limited availability can lead to higher costs and longer wait times for those seeking aluminium alternatives.
While aluminium tubing is suitable for fuel lines and offers the benefit of being easy to bend by hand, it falls short in terms of strength and durability when compared to steel. Aluminium can be prone to weakening over time due to repeated cycles of low and high pressure. This can lead to potential safety concerns, especially if the aluminium lines are poorly routed or protected. As a result, steel is often recommended as a safer and more reliable option for brake lines, ensuring that vehicles can stop effectively.
In summary, steel brake lines offer a cost-effective, durable, and easily accessible solution for both brake and fuel line applications. Their strength, wide availability, and ease of use make them a preferred choice over aluminium alternatives, ensuring both functionality and affordability for vehicle owners and enthusiasts alike.

Steel is harder to bend and more prone to rust than aluminium
Steel brake lines have been used for fuel lines in the past without any issues. However, steel and aluminium have different properties that may make aluminium a more suitable choice in certain situations.
One key difference between steel and aluminium is that steel is harder to bend than aluminium. This is due to the different crystalline structures of the two metals. Steel has a higher yield point, which means it requires more force to deform. On the other hand, aluminium is generally considered more formable, and bending it can even increase its strength. This is known as work hardening, where the metal's crystalline structure becomes more complex and resistant to pressure as it is bent.
Additionally, steel is more prone to rust than aluminium. Steel alloys contain iron, which quickly oxidises to form rust when exposed to oxygen and water. While stainless steel alloys contain chromium, which provides some rust resistance, they still have a higher tendency to rust than aluminium alloys, which contain little to no iron. Aluminium will not rust but will instead form an aluminium oxide film on its surface when exposed to water, protecting it from further oxidation.
Given these factors, aluminium may be a preferred choice in applications where flexibility and corrosion resistance are important. However, it is important to note that each alloy of steel and aluminium may have unique properties, and the specific type of metal used can significantly impact its performance.

Poly-Armour® steel tubing is coated with Polyvinyl Fluoride, which resists rust better than galvanised steel
Steel brake lines are commonly used for fuel lines, especially in vintage cars. The only difference between fuel and brake lines is the diameter of the line, not the composition of the metal.
Poly-Armour® steel tubing is a popular choice for brake lines, offering a highly durable coating that provides superior protection against corrosion and rust. This tubing is coated with Polyvinyl Fluoride (PVF), a polymer that is baked and cured onto the steel line during production. PVF provides a robust barrier against external causes of corrosion and rust, such as road salt and slush, making it ideal for vehicles operating in harsh environments.
Poly-Armour® steel tubing with its PVF coating offers several advantages over galvanised steel. Firstly, PVF provides superior resistance to rust and corrosion. While galvanised steel offers some protection through the hot-dip galvanisation process, it is still susceptible to constant exposure to salt and moisture, which can lead to corrosion over time. In contrast, PVF provides a more durable barrier, making it a better choice in areas where rust and corrosion are prevalent.
Secondly, Poly-Armour® steel tubing is more flexible and easier to work with. The PVF coating allows for superior bendability without kinking, making it simpler to flare and form during installation or repairs. This flexibility also makes it suitable for custom lengths and non-standard applications, providing a versatile option for professionals and DIY enthusiasts alike.
Finally, Poly-Armour® steel tubing offers a longer lifespan. With 30 times the corrosion resistance of galvanised steel, it surpasses factory standards and extends the life of brake lines, especially in challenging conditions. This makes it a cost-effective choice for commercial vehicles or situations where exact OEM replacement is required.
In summary, Poly-Armour® steel tubing coated with Polyvinyl Fluoride offers enhanced rust and corrosion protection, improved flexibility, and a longer lifespan compared to galvanised steel. Its durability and ease of use have made it the new standard in brake line replacement, favoured by professionals and DIYers alike.

Stainless steel tubing is more expensive than regular steel but won't rust
Using steel brake lines for fuel lines is a common practice, especially for carbureted applications. The key consideration when using steel brake lines for fuel is ensuring the line diameter is adequate, as fuel systems operate at lower pressures than brake systems. A 5/16" or 3/8" diameter line is typically sufficient for most fuel applications.
Now, regarding stainless steel tubing, it is indeed more expensive than regular steel, but it offers the significant advantage of being highly resistant to rust and corrosion. This is because stainless steel typically contains more alloying elements, such as chromium, which form a protective layer on the surface of the metal, preventing oxidation and rust. While regular steel may be more affordable, it will require additional maintenance and care to prevent rust, especially in humid environments.
The higher cost of stainless steel tubing is due to several factors. Firstly, the addition of alloying elements during the manufacturing process increases the material and production costs. Secondly, the forming and welding processes required to create stainless steel tubing can be more complex and time-consuming, further elevating the overall expense.
However, despite the higher upfront cost, stainless steel tubing can be more cost-effective in the long run, especially in harsh or corrosive environments. The superior corrosion resistance of stainless steel means it requires less maintenance, and its longer lifespan can offset the initial investment. Additionally, stainless steel tubing is highly versatile and widely used in critical applications across various industries, including automotive, aerospace, medical, and marine fields, due to its strength, durability, and resistance to high pressure.
In conclusion, while stainless steel tubing carries a higher price tag than regular steel, its resistance to rust and corrosion, coupled with its superior strength and versatility, make it a preferred choice for many applications where reliability and longevity are paramount.

Brake systems see much higher pressure than fuel systems, so steel tubing is strong enough for fuel lines
Steel brake lines can be used for fuel lines, especially given that brake systems see much higher pressure than fuel systems. Steel tubing is strong enough for fuel lines, and stainless steel, in particular, is a good option as it will never rust.
Brake systems can see pressures of 1000-2000 psi, while fuel systems produce 30-60 psi. As such, steel brake lines are more than capable of handling the pressure of a fuel system. This is especially true if the steel tubing is large enough in diameter (5/16 or 3/8 inches in diameter).
Steel is a common choice for brake lines because it is affordable, durable, and easy to source. However, steel is also difficult to bend and prone to rust. To combat this, some steel tubing is galvanized to protect the surface from moisture, which can lead to rust. Another option is Poly-Armour®, a type of steel tubing coated with Polyvinyl Fluoride (PVF), a plastic coating that is baked and cured onto the steel line. This coating does not flake or chip and protects the steel from rust up to 30% better than galvanizing.
Some people have used steel brake lines for fuel lines without encountering any issues. However, it is important to note that the diameter of the line may need to be larger for a fuel line than for a brake line. Additionally, aluminum is another option for fuel lines, as it is easy to bend by hand, although it may not be as strong as steel.
