The toughness of a fuel line compared to a transmission line depends on the context. Fuel lines are made of a variety of materials, including rubber, braided rubber, solid copper, aluminium, galvanized zinc, stainless steel, and more. Transmission lines are usually made of steel, with a short piece of rubber connecting the line to the cooler. Rubber fuel lines are rated for approximately 50 psi, while those for injected engines are rated for over 200 psi. This is adequate for transmission pressures. However, transmission lines are designed to withstand the oil and additives in transmission fluid for longer than fuel lines. Additionally, transmission lines are reinforced to withstand higher pressures and temperatures, while fuel lines may not be able to handle the heat and pressure associated with automatic transmissions.

Fuel line hoses are not designed to withstand the pressure of automatic transmissions
Fuel line hoses are designed to handle the pressure of fuel, which can vary depending on the type of engine. For example, fuel hose for carbureted engines is typically rated for around 50 psi, while fuel hose for injected engines can be rated for over 200 psi. Transmission line hoses, on the other hand, are designed to handle much higher pressures. For example, the Goodyear 5/16" transmission oil cooler hose is rated for 250 psi.
Using a fuel line hose for an automatic transmission can work in the short term, but it is not a long-term solution. The higher pressure of the transmission fluid can cause the fuel line hose to rupture, leak, or fail prematurely. Additionally, the chemicals in transmission fluid can cause the fuel line hose to swell and soften over time, leading to a higher risk of failure.
It is important to use the correct type of hose for your application. While it may be tempting to use a cheaper or more readily available option, such as a fuel line hose, it is not worth the risk of failure or damage to your vehicle. Always use the proper transmission line hose for your automatic transmission to ensure reliable and safe operation.
Some people may choose to use fuel line hoses for their automatic transmissions due to their lower cost and easier availability. However, it is important to note that this is not a recommended practice and can lead to dangerous consequences. Transmission line hoses are designed to withstand higher pressures and the unique chemical composition of transmission fluids. By using a fuel line hose, you increase the risk of leaks, ruptures, and other failures that could potentially damage your vehicle or even lead to a fire. Therefore, it is always advisable to use the correct transmission line hose to ensure the safe and efficient operation of your vehicle's transmission system.

Transmission lines are reinforced to withstand more pressure and heat
Transmission lines are designed to be reinforced to withstand more pressure and heat. They are made of materials such as steel-reinforced aluminium, aluminium alloys, copper alloys, and composite materials. The reinforcement in transmission lines is necessary to prevent them from sagging under the weight of the load they carry and to ensure they do not come into contact with obstacles such as trees.
In the context of vehicles, transmission lines are often made of a heavier-duty hose that can withstand the oil and additives in the transmission fluid. The transmission cooler hose is noticeably thicker and stiffer than a fuel hose, and it is designed to withstand the chemicals in the transmission fluid that can cause swelling and softening of a regular fuel line, leading to a rupture.
Transmission lines are also designed to be more rigid and less likely to collapse under pressure. The pressure in transmission lines is generally higher than in fuel lines, and as a result, transmission lines are manufactured to have a higher PSI rating.
In the case of electricity transmission lines, the lines themselves are often sturdier than the electrical towers and insulating systems. These transmission lines are designed to hold up in adverse weather conditions and can last up to 100 years if kept clean. The increased demand for electricity due to new devices, appliances, and equipment adds a new dimension to the question of their durability.
Overall, transmission lines, whether in the context of vehicles or electricity transmission, are reinforced to handle higher pressures and temperatures than fuel lines.

Transmission lines are also designed to withstand the difference in chemicals in transmission fluid
The transmission line and the fuel line serve different purposes in an automobile. While the fuel line is designed to carry fuel from the tank to the engine, the transmission line is designed to carry transmission fluid, which serves as a lubricant and coolant for the transmission system.
The transmission fluid is subject to a range of temperatures, and its physical and chemical properties vary with temperature. For instance, as the temperature increases, the fluid's air solubility, volumetric thermal expansion, and specific heat increase, while its surface tension, specific gravity, viscosity, bulk modulus, density, thermal conductivity, and electrical resistivity decrease.
The transmission line is designed to withstand these changes in the properties of the transmission fluid. It is also reinforced to withstand the chemicals in the transmission fluid, which differ from those in most types of fuel, including diesel. The transmission line is made from materials that can withstand the swelling and softening that regular fuel lines experience due to the chemicals in the transmission fluid.
The fuel line, on the other hand, is not designed to withstand the same range of chemicals and temperatures as the transmission line. It is usually rated for lower pressure and may not be suitable for the higher pressures associated with automatic transmissions. Using a fuel line for the transmission line can lead to a ruptured line, potentially causing a fire hazard. Therefore, it is essential to use the proper transmission line designed for the specific application.

Fuel lines are rated at 250 psi, while transmission lines are rated at 200 psi
Fuel lines are designed to handle different types of fuel, including unleaded and leaded gasoline, diesel, biodiesel, E-85, 100% methanol, ethanol, and gasohol fuels. These fuels can be harder on hoses than transmission oil. The psi rating of a fuel hose depends on the type of engine, with carbureted engines having a lower rating of around 50 psi, while injected engines have a higher rating of over 200 psi.
Transmission lines, on the other hand, are designed to withstand the oil and additives in transmission fluid. They are reinforced to handle higher temperatures and the chemicals in the fluid, which can cause regular fuel lines to swell and soften, leading to a ruptured line.
While fuel lines have a higher psi rating, it is important to note that they are not suitable for use with transmission fluid. Transmission fluid can have temperatures of 200-230 degrees, which can degrade a fuel line. Additionally, the rubber compounds in transmission cooler hoses are designed to handle the fluid without deteriorating.
It is recommended to use the appropriate type of hose for each application to ensure safety and longevity.

Transmission lines are more expensive than fuel lines
It is clear that transmission lines are more expensive than fuel lines. This is true in terms of both the cost of the lines themselves and the wider costs associated with their use.
Firstly, in terms of the lines themselves, transmission cooler lines are said to cost around three times as much as fuel lines. This is because transmission lines are noticeably thicker and stiffer than fuel lines, and they are designed to withstand more pressure and heat. Transmission lines are also reinforced to withstand the chemicals in transmission fluid, which can cause regular fuel lines to swell and soften, leading to a ruptured line.
Secondly, the use of transmission lines is more expensive than the use of fuel lines. This is because electrical transmission lines have a much lower energy-carrying capacity than fuel lines. This means that multiple electrical transmission lines would have to be built to transport the same amount of energy as a single high-capacity fuel pipeline. As a result, the cost of electrical transmission per delivered MWh can be up to eight times higher than for hydrogen pipelines, about eleven times higher than for natural gas pipelines, and twenty to fifty times higher than for liquid fuel pipelines.
In addition, the operating energy losses are much greater in electrical transmission lines than in chemical fuel pipelines. This is due to the lower carrying capacity of electrical transmission lines, which means that more lines are required to transmit the same amount of energy, resulting in higher overall energy losses.
Finally, it is worth noting that the cost of producing liquid fuels, such as methanol, using renewable electricity is currently more expensive than using common industrial electricity or fossil fuels. However, this may change in the future as the large-scale deployment of e-fuel production technologies could reduce the production cost of e-fuels, making them cost-competitive with fossil fuel alternatives.
