Transmission fluid and fuel hose are not a good combination. While some people claim that fuel hose can be used for transmission fluid, it is not a long-term solution. The transmission fluid will eventually eat up the fuel hose, causing it to rupture. The chemicals in transmission fluid are different from most types of fuel, and the heat and pressure of the transmission fluid can cause the fuel hose to swell and soften, leading to leakage. It is recommended to use a transmission cooler hose, which is designed to withstand the specific conditions of transmission fluid and prevent potential damage to your vehicle.

What You'll Learn
Fuel line hoses are not designed for oil
While some people have used fuel line hoses for transmission fluid, it is not recommended. Fuel line hoses are designed for lower pressures and the transmission fluid will eventually eat up the hose. The chemicals in transmission fluid are different from most types of fuel, including diesel, and the fluid can cause swelling and softening of a regular fuel line, leading to a ruptured line.
Fuel line hoses are designed for fuel applications and are vital components responsible for delivering fuel from the tank to the engine. They come in a variety of materials, including metal, rubber, braided nylon, braided steel, PTFE-lined, or plastic. It is important to use the correct type of hose for a particular fuel or application to avoid performance issues and costly repairs.
Transmission cooler hoses, on the other hand, are designed to withstand the oil and additives in transmission fluid. They are noticeably thicker and stiffer, and the type of rubber used is designed to work long-term with transmission fluid. Using a fuel line hose for transmission fluid may seem convenient, but it is not worth the risk of failure, which could lead to costly repairs and safety hazards.
It is always best to use hoses specifically designed for their intended purpose. While a fuel line hose may work in the short term, it is not a reliable solution and can cause more problems in the long run. By choosing the appropriate hose for your transmission fluid, you can ensure the optimal performance and safety of your vehicle.

Transmission fluid is chemically different from fuel
While fuel line hose can be used for transmission fluid, it is not recommended for long-term use. Transmission fluid is chemically different from fuel, and these differences can cause damage to the fuel line hose over time.
Transmission fluid, or automatic transmission fluid (ATF), is a hydraulic fluid essential for vehicles with automatic transmissions. It has a thinner consistency and is typically red, green, blue/green, purple, or amber, depending on the manufacturer, to differentiate it from other vehicle fluids. ATF consists of a base oil and an additive package containing various chemical compounds designed to meet the unique demands of automatic transmissions. These additives improve lubricating qualities, provide hydraulic pressure and friction, and help keep the transmission cool.
The base oil used in ATF can be made from crude oil or synthetic through different chemical reactions. Synthetic transmission fluid is less likely to break down, oxidize, or thin out in high temperatures. Lifetime ATF is made from higher-quality base oil and is more chemically stable, less reactive, and more resistant to oxidation.
On the other hand, fuel includes gasoline, diesel, biodiesel, E-85, 100% methanol, ethanol, and gasohol. These fuels are harder on hoses than transmission fluid.
Due to the chemical differences between transmission fluid and fuel, using a fuel line hose for transmission fluid can lead to issues. The transmission fluid may cause swelling and softening of the fuel line hose, leading to a ruptured line. Additionally, the fluid can eat up the hose over time. Therefore, it is recommended to use the appropriate transmission line or a heavier-duty hose for transmission fluid to ensure the long-term durability of the hose.

Transmission fluid will eat up the fuel hose
While some people have used fuel line hoses for transmission fluid, it is not recommended. Transmission fluid and fuel hose do not work well together in the long term. The fluid will eventually eat up the fuel hose, causing it to rupture.
The difference between a fuel line and a transmission cooler line is that the latter is designed to withstand the chemicals in transmission fluid, which can cause swelling and softening of a regular fuel line. Transmission cooler lines are also reinforced to withstand more pressure and heat.
Some people have reported that fuel line hoses have worked for them without any issues. However, others have found that the fuel line hose started to weep almost immediately after installation. It is recommended to use the proper transmission line to avoid potential issues and the cost of a new transmission.
While fuel line hoses may work in the short term, it is not a permanent solution. The chemicals in transmission fluid are different from most types of fuel, and the transmission fluid will eventually degrade the fuel line hose. It is best to use a hose specifically designed for hydraulic fluid or transmission fluid to ensure the longevity of your vehicle's systems.
In summary, while it may be tempting to use a fuel line hose for transmission fluid due to its lower cost and availability, it is not a good idea. The transmission fluid will eventually eat up the fuel hose, leading to potential leaks and costly repairs. It is always best to use the correct type of hose for your vehicle's systems to ensure optimal performance and longevity.

Transmission cooler hose is noticeably thicker and stiffer
The transmission cooler hose is noticeably thicker and stiffer than the fuel line hose. This is because the transmission cooler hose is designed to withstand the chemicals in transmission fluid, which can cause swelling and softening of regular fuel hoses, leading to a ruptured line.
The transmission fluid is also under higher pressure than fuel, and the thicker walls of the transmission cooler hose can better withstand this pressure without collapsing or leaking. The transmission cooler hose is also reinforced to withstand more pressure and heat.
While some people have reported success using fuel line hoses for transmission fluid in the short term, others have found that the fluid starts to eat away at the hose almost immediately, causing it to weep or leak. It is generally recommended to use the correct type of hose for your application to avoid potential issues down the line.
The transmission cooler hose is made of a different type of rubber that is more compatible with transmission fluid and will not break down as quickly as a fuel line hose. It is important to consider the long-term durability and safety of the hose, especially when dealing with fluids that can be hazardous if they leak.

Fuel line hoses are rated for fuel and oil
However, when it comes to transmission fluid, there are some concerns about the compatibility of fuel line hoses. While some sources suggest that fuel line hoses can work for transmission fluid in the short term, others warn that the chemicals in transmission fluid can eventually cause the fuel line hose to soften, swell, and rupture. This is because transmission fluid contains different additives and chemicals than most types of fuel, and these can degrade the rubber or other materials in the hose over time.
It is recommended to use a hose specifically designed for transmission fluid, also known as a transmission cooler hose or tranny cooler line, as it is thicker, stiffer, and designed to withstand the specific chemicals and pressure requirements of transmission fluid. These hoses are typically more expensive than fuel line hoses, but they provide greater durability and peace of mind.
Additionally, it is worth noting that the working pressure of a hose is an important consideration when selecting a fuel line hose or a transmission cooler hose. Hoses with higher pressure ratings, such as those used for injected engines, may be more suitable for certain applications, and it is always important to ensure that the hose is properly rated for the specific fluid it will carry.
In conclusion, while fuel line hoses are rated for fuel and oil, it is important to consider the specific requirements of the application, including the type of fluid, pressure, heat, and chemical compatibility. For transmission fluid, it is generally recommended to use a transmission cooler hose for long-term durability and reliability.
