What You'll Learn
Ethanol in fuel can degrade transmission lines
Ethanol is often added to gasoline as a way to improve the octane rating. It also serves as an oxygenator, reducing carbon monoxide emissions and thus, pollution. However, ethanol in fuel can have detrimental effects on rubber fuel lines, causing them to dry out and degrade, which can lead to leaks and potentially serious fire hazards. This issue is particularly prevalent in older fuel systems that use simple neoprene rubber fuel lines.
While some newer vehicles have adopted fuel lines made with alternative materials, such as braided steel and chlorinated polyethylene (CPE)-based materials, these lines have also proven to be susceptible to degradation over time due to changes in fuel blending. As a result, several companies now offer PTFE-style performance hoses, which are more expensive but provide greater resistance to the detrimental effects of ethanol-blended fuels.
To mitigate the potential damage caused by ethanol, some drivers have turned to fuel treatment additives, specifically fuel stabilizers, which claim to neutralize the harmful effects of ethanol on rubber lines. Additionally, regular inspection and maintenance of fuel lines are crucial, especially for vehicles that are seasonally stored or have two-cycle motors, as they are highly susceptible to ethanol damage.
Furthermore, the process of "Phase Separation" can occur in fuel tanks, where water and ethanol separate from the gasoline and sink to the bottom. This leads to issues such as valve damage, carburetor problems, and fuel line degradation when the water-ethanol mixture is sent to the engine. Thus, ethanol in fuel can indeed contribute to the degradation of transmission lines, particularly those made of rubber, and it is important for vehicle owners to take preventative measures to minimize potential issues.

Transmission fluid can eat up fuel lines
Transmission fluid is essential for ensuring that a vehicle's transmission system functions correctly. It helps to lubricate the gears and prevent damage caused by gears grinding against each other. It also contains additives that clean and protect the metal surfaces of gears and clutches, ensuring smooth and efficient gear changes. While transmission fluid is crucial for the smooth operation of a vehicle, it can also have detrimental effects on certain components, such as fuel lines.
The transmission fluid's chemical composition can cause swelling and softening of regular fuel lines, leading to potential rupture. This is because the chemicals in the transmission fluid can degrade the fuel lines over time. As a result, it is recommended to use dedicated transmission cooler lines, which are designed to withstand the chemicals and pressure of the transmission fluid. These lines are typically made of reinforced materials that offer higher resistance to degradation.
It is important to note that transmission fluid and fuel lines are not compatible in the long term. While using a fuel line for transmission fluid may work temporarily, prolonged exposure will eventually cause the fuel line to deteriorate. This is due to the transmission fluid's corrosive nature, which can eat away at the material of the fuel line. Therefore, it is crucial to use the appropriate type of hose for each application to prevent potential damage and ensure the proper functioning of the vehicle's systems.
The choice of hose for transmission fluid is crucial, and several options are available. One option is to use a hose rated for petroleum, such as SAE 30R6, 30R7, 30R9, or 30R14 Type 1. These hoses are designed to withstand the chemicals and pressure of transmission fluid and prevent fuel vapour from degrading the reinforcement. Additionally, some hoses are constructed with a thin plastic permeation barrier, providing an extra layer of protection against degradation.
In conclusion, transmission fluid plays a vital role in the smooth operation of a vehicle's transmission system. However, it is important to use the correct components, as the fluid can have detrimental effects on certain materials, such as fuel lines. By using dedicated transmission cooler lines and hoses rated for petroleum, vehicle owners can prevent potential damage and ensure the long-term reliability of their vehicles.

This is because transmission fluid is designed to withstand higher temperatures and pressures than fuel lines. Over time, the transmission fluid will eat up the fuel hose, causing it to fail.
It is important to note that there are different types of fuel lines, and not all of them are compatible with transmission fluid. For example, the transmission cooler line is specifically designed to withstand the higher temperatures and pressures of transmission fluid. It is reinforced to handle the chemicals in transmission fluid that can cause issues with regular fuel lines.
When choosing a fuel line, it is important to consider the type of fluid it will be carrying. Using the wrong type of fuel line can lead to leaks, ruptures, and other issues. It is always best to consult a mechanic or automotive expert when making these types of decisions to ensure the safety and proper functioning of your vehicle.
In some cases, it may be necessary to use a transmission cooler line as a fuel line. This is typically done when there is a need for a flexible fuel line and the regular fuel line is not sufficient. However, it is important to note that transmission cooler lines are more expensive than regular fuel lines.
Overall, it is important to consider the compatibility of the fuel line with the type of fluid it will be carrying. Transmission fluid can cause swelling and softening of regular fuel lines, leading to potential failures and safety hazards. By choosing the appropriate fuel line for your vehicle and maintaining it properly, you can help ensure the optimal performance and longevity of your engine.

Transmission cooler lines are reinforced to withstand pressure and heat
Transmission cooler lines are integral to the health of a vehicle's transmission system. They carry transmission fluid to the vehicle's radiator or auxiliary cooler to reduce the temperature and then return the cooled fluid back to the transmission. This process is crucial as transmissions do not respond well to heat, and the fluid helps to cool the internal transmission components. Therefore, the lines are designed to withstand pressure and heat to ensure the transmission fluid can perform its role effectively.
There are several types of transmission cooler lines, including rubber hoses, metal lines, and braided lines. Each type is designed for specific applications and system requirements. Rubber hoses are commonly used due to their flexibility and cost-effectiveness. They are made from durable synthetic rubber that can withstand high temperatures and pressures, as well as being resistant to oil and other chemicals in the transmission system. However, they can deteriorate at the crimp site due to excessive heat, leading to leaks.
Metal lines, on the other hand, are often used in vehicles requiring higher hydraulic pressure, such as trucks and commercial vehicles. They offer excellent resistance to corrosion and can withstand extreme temperatures, ensuring reliable performance in harsh conditions. Metal lines are more durable than rubber hoses and provide better resistance to high-pressure environments. They also use preformed and flared connections that last longer and prevent leaking issues found in straight rubber lines.
Braided lines, typically made of stainless steel, offer a combination of flexibility and strength, making them ideal for high-performance vehicles. The stainless steel braiding provides added protection against abrasion and external damage, ensuring the longevity of the transmission lines.
In summary, transmission cooler lines are reinforced with specific materials and designs to withstand the pressure and heat generated by the transmission system. This reinforcement ensures the reliable performance of the transmission fluid, which is crucial to the overall health and longevity of the vehicle's transmission.
