There is some debate over whether a fuel line can be used for transmission fluid. Some people argue that the two types of hoses are manufactured from the same material, and that a fuel line will work for transmission fluid. However, others claim that the chemicals in transmission fluid are different from most types of fuel, and that the transmission line has a higher working and burst strength. It is also said that the transmission fluid will eventually eat up the fuel hose, causing it to soften, swell, and leak. Therefore, it is recommended to use a transmission line for transmission fluid and a fuel line for fuel to avoid any potential issues or damage to your vehicle.

Fuel line hoses can be used as a quick fix but may not be a long-term solution
Fuel line hoses can be used as a quick fix for transmission fluid but may not be a long-term solution. While fuel line hoses will work in the short term, there are notable differences between fuel lines and transmission cooler lines that make the latter a more durable option.
Firstly, transmission fluid contains different chemicals than most types of fuel, including diesel. These chemicals can cause the regular fuel line to swell and soften over time, leading to a ruptured line. The transmission line is designed to withstand the oil and additives in the transmission fluid, preventing the line from deteriorating.
Secondly, transmission lines have a higher working strength and burst strength than fuel lines. They are noticeably thicker and stiffer, making them more resistant to pressure and less likely to collapse. This added durability reduces the risk of the hose blowing and dumping the transmission fluid, which could cause significant damage to the vehicle.
Additionally, heat is a factor that needs to be considered. Transmission fluid operates at higher temperatures than fuel, and the transmission line is designed to withstand this heat. Regular fuel lines may not be able to handle the increased temperature, leading to potential issues such as weeping or leakage.
While some people have reported using fuel line hoses for transmission fluid without any problems, it is generally recommended to use the correct transmission line to avoid potential long-term issues. The transmission line is specifically designed to handle the unique characteristics of transmission fluid and the operating conditions of the transmission system, ensuring optimal performance and durability.
In conclusion, while fuel line hoses can be used as a temporary fix, they may not provide the same level of durability and reliability as transmission cooler lines. For a long-term solution, investing in the proper transmission line is the best course of action to ensure the safe and efficient operation of your vehicle.

Transmission fluid has different chemicals to most types of fuel, including diesel
While it is possible to use a fuel line for transmission fluid, it is not recommended. The chemicals in transmission fluid are different from most types of fuel, including diesel. Transmission fluid contains a variety of chemicals, including petroleum-based oils, anti-wear agents, friction modifiers, detergents, dispersants, anti-foam agents, corrosion inhibitors, and seal conditioners. On the other hand, diesel fuel typically contains a mixture of hydrocarbons, including alkanes, alkenes, and aromatic compounds. These differences in chemical composition can have a significant impact on the performance and longevity of the fuel line.
One of the main concerns with using a fuel line for transmission fluid is its ability to withstand the heat and pressure generated by the transmission. Transmission fluid operates at higher temperatures and pressures than fuel, and the fuel line may not be designed to handle these conditions. Over time, the heat and pressure can cause the fuel line to soften, swell, and become brittle, leading to leaks or ruptures.
Additionally, the chemicals in transmission fluid can interact differently with the materials commonly used in fuel lines, such as rubber or plastic. The transmission fluid's detergents, for example, may cause the fuel line to degrade more quickly, leading to a loss of flexibility and increased brittleness. The higher temperatures of transmission fluid can also accelerate this degradation process, further compromising the integrity of the fuel line.
Furthermore, transmission fluid often contains additives that are not typically found in fuel. These additives, such as friction modifiers and anti-wear agents, can have a detrimental effect on the fuel line. They may cause the line to swell or become brittle, or they may interact negatively with the materials of the fuel line, leading to leaks or blockages.
While some individuals have reported success in using a fuel line for transmission fluid in the short term, it is generally advised to use the appropriate transmission line to avoid potential issues. Transmission lines are specifically designed to withstand the unique characteristics of transmission fluid, including its chemical composition, temperature, and pressure. By using the correct transmission line, you can help ensure the reliable and safe operation of your vehicle's transmission system.

Transmission fluid is thicker and will hold up better to detergents
Transmission fluid is designed to be highly detergent, and its detergents are 1/15th to 1/20th the levels in engine oils. The detergents are necessary to reduce or remove varnish and any oxidation products that may form. Varnish can glaze clutch packs and cause the valving in the valve body to stick.
The detergents in the transmission fluid can also cause swelling and softening of a regular fuel line, which will lead to a ruptured line. This is because the chemicals in transmission fluid are different from most types of fuel, including diesel.
While some people have used fuel line hoses for transmission fluid without incident in the short term, others have reported that the inside of the fuel line must be a lot slicker, or that it is a heat issue and fuel line is not meant for heat. Therefore, it is recommended to use an actual transmission line.

Transmission lines have five times more working strength and four times more burst strength
Transmission lines are used to carry electromagnetic signals with minimal reflections and power losses. They are designed with specialized construction and impedance matching to achieve this. One key feature is their uniform cross-sectional dimensions, which give them a uniform impedance, preventing reflections.
In the context of automobiles, transmission lines refer to hoses or pipes that carry transmission fluid. These lines are specifically designed to withstand the unique characteristics of transmission fluid, including its chemical composition, pressure, and heat.
Goodyear transmission lines, for example, are known for their superior strength and durability. They are designed with five times the working strength and four times the burst strength of standard fuel lines. This means they can withstand higher pressures and resist rupturing.
While some people choose to use fuel lines as transmission lines, this is not recommended for the long term. Fuel lines are not designed to withstand the chemicals, heat, and pressure of transmission fluid over an extended period. They may work temporarily, but the transmission fluid can eventually cause the fuel line to soften, swell, or rupture. Therefore, it is advisable to use the correct transmission line to avoid potential damage to your vehicle.

Steel or aluminium lines are best, but braided teflon lines are also an option
When it comes to choosing the best fuel line, several factors come into play, including durability, safety, and ease of installation. While various materials can be used, steel or aluminium lines are widely regarded as the best options due to their superior strength and resistance to abrasion and corrosion.
Steel fuel lines, often made from stainless steel or coated steel, offer exceptional durability. They can withstand harsh conditions and are highly resistant to ripping or rupturing. Steel lines provide a high level of safety, especially when compared to other options like braided lines, making them a trusted choice for many vehicle owners. However, one potential drawback of steel lines is the fabrication challenge they present.
Aluminium fuel lines, on the other hand, are also a popular choice. Aluminium is known for its lightweight yet sturdy nature, making it ideal for fuel line applications. Similar to steel lines, aluminium lines offer excellent resistance to abrasion and corrosion, ensuring a long-lasting and reliable performance. Additionally, aluminium is a relatively soft metal, making it easier to work with during the installation process.
While steel and aluminium lines are considered the best options, there is another contender in the market: braided Teflon lines. These lines, also known as PTFE (polytetrafluoroethylene) braided lines, offer unique advantages. PTFE is chemically inert, making it compatible with various fluids, including transmission fluids. It is also known for its outstanding flow capacity and extended service life. PTFE braided lines are often reinforced with a stainless steel outer braid, providing enhanced impact and abrasion resistance while protecting the inner liner.
One consideration to keep in mind with PTFE braided lines is the potential issue of fuel vapour seepage. While PTFE does an excellent job of blocking fuel vapours, some users have reported noticing fuel vapour smells with this type of line. This issue is more commonly associated with rubber or nylon lines, which are known to degrade and leak fuel vapours over time.
