Fuel lines are essential components of fuel systems, facilitating the transfer of fuel from the tank to the engine. While they are designed to handle fuel, a common question arises regarding their ability to be fully submerged in fuel. This query stems from concerns about the potential damage caused by prolonged exposure to fuel on both the interior and exterior of the fuel line. The answer lies in understanding the specific design and materials used in the construction of these fuel lines, as well as exploring alternative options like submersible fuel hoses.

What You'll Learn
Regular fuel hoses are not rated to be submerged in gas
Regular fuel hoses are not designed to be submerged in gas. They are only designed to handle fuel on the interior of the hose, and submerging the exterior of the hose in fuel can cause damage. This is because the outer layer of a standard fuel hose is often not fuel-proof.
If you need a fuel hose that can be fully submerged in gasoline or other fuel fluids, you will need to purchase a special submersible fuel hose. These hoses are designed for constant contact with fuel and can handle multiple types of gasoline and fuels, including gasoline, alcohol-extended gasoline, ethanols, biodiesel, and diesel fuel. They are excellent for use on gas tank fuel pumps and offer a range of benefits, including enhanced environmental protection and better fuel efficiency.
There are several companies that manufacture submersible fuel hoses, including Gates Corporation and Radium Automotive. These hoses can be purchased online or from specialty stores and typically cost around $16 to $20 per foot. While this is more expensive than a standard fuel hose, it is important to use the correct hose for your application to avoid issues and potential safety hazards.
It is also worth noting that some materials, such as nylon, are not suitable for use in fuel hoses, even if they are "fuel-rated." Nylon will degrade and destroy itself within a couple of years, even if it is only exposed to fuel on the inside. Therefore, it is crucial to choose the right type of hose and consider the specific fuel type and application when making your selection.

Nylon fuel lines will degrade over time
Nylon fuel lines are not designed to be submerged in fuel. Most fuel lines are only designed to handle fuel on the interior of the hose, and exposing the exterior to fuel can cause damage. Regular fuel hoses are not rated to be submerged in gas.
Nylon fuel lines can be repaired, but it is important to have the proper tools. Without the right tools, it can be difficult to install the end fittings, and the line may become kinked. There are special tools available, such as a hose press or a hose assembly press, that can make the job easier and more enjoyable.
It is worth noting that some car manufacturers, such as Porsche, Volvo, and Aston Martin, use nylon fuel lines as original equipment. However, steel is still the most common material used for fuel lines, especially in the fuel tank and on the firewall and fuel rail.
In conclusion, while nylon fuel lines have their advantages, they may not be the best option for the long term due to their degradation over time and the need for occasional repairs.

Fuel-resistant rubber tubing can be submerged in fuel
It is important to note that regular fuel hoses are not designed to be submerged in fuel. Most fuel lines are only intended to handle fuel on the interior of the hose, and exposing the exterior to fuel can cause damage.
However, there are special fuel-resistant rubber tubings, known as submersible fuel hoses, that are designed for full submersion in fuel. These hoses are commonly used for in-tank applications and fuel systems where the hose is in constant contact with gasoline or other fuel fluids. The Gates Submersible Fuel Hose, for example, is capable of handling various types of gasoline and fuels, including gasoline, alcohol-extended gasoline, ethanols, biodiesel, and diesel fuel. It is engineered for fully submersible use and is suitable for gas tank fuel pumps.
The submersible rubber fuel hoses are made from materials that are resistant to gasoline and oil, such as nitrile rubber (also known as Buna-N). While these hoses are more expensive than standard fuel hoses, they are essential to prevent damage and ensure the proper functioning of the fuel system.
It is worth noting that some OEMs (original equipment manufacturers) use submersible hoses or corrugated plastic lines for added flexibility. However, these hoses have a finite lifespan and will eventually need to be replaced.

Submersible fuel hoses are more expensive than regular fuel hoses
Regular fuel hoses are not designed to be submerged in fuel. They are only meant to handle fuel on the interior of the hose, and exposing the exterior to fuel can cause damage. If you need to submerge a fuel hose in fuel, you will need to purchase a special submersible fuel hose. These hoses are made of materials that can withstand constant contact with fuel, such as FKM tubes and synthetic fiber reinforcement.
The cost of submersible fuel hoses can vary depending on the brand and specifications. Some hoses can cost around $20 per foot, while others may be even more expensive. It's important to note that using the wrong type of hose can lead to costly repairs and breakdowns, so it's crucial to invest in the correct submersible fuel hose for your specific application.
While the initial cost of submersible fuel hoses may be higher, they offer better value in the long run. Regular fuel hoses that are not designed for submersion may deteriorate when exposed to fuel, leading to potential leaks and costly repairs. By investing in a submersible fuel hose, you can avoid these issues and maintain the integrity of your fuel system.
In addition to the cost of the hose itself, there may be other expenses to consider. For example, if you require a custom length for your application, you may need to purchase a minimum order quantity from the supplier. Additionally, if you need to replace a non-submersible hose with a submersible one, you may incur labor costs for the installation. Therefore, it's important to carefully consider your specific requirements and consult with experts to ensure you make the right choice for your fuel system.

Submersible fuel hoses are available in custom lengths
Regular fuel hoses are not designed to be submerged in fuel. They are only meant to handle fuel on the inside, and exposing the exterior to fuel can cause damage. This is where submersible fuel hoses come in.
Submersible fuel hoses are designed for constant contact with fuel and other liquid petroleum products, both inside and out. They are excellent for use on gas tank fuel pumps. These hoses are made from a special compound called Fluoroelastomer (FKM), which resists gas permeation and aging. They are also reinforced with Aramid Fibre, which is stronger than steel.
Gates Corporation is one manufacturer of submersible fuel hoses. Their hoses can handle multiple fuel types, including gasoline, alcohol-extended gasoline, ethanols, biodiesel, and diesel fuel. They exceed the required SAE 30R10 standard and have a working pressure of up to 100 PSI. The temperature tolerance range of these hoses is -40°C to +150°C (-40°F to +302°F).
Submersible fuel hoses from Gates are available in custom lengths. They can be pre-cut to the specific length required by your application with a minimum order. This ensures that you get a hose that fits your exact needs. Other companies, like Dayco, also offer submersible fuel hoses in a variety of sizes and lengths.
When purchasing a submersible fuel hose, it is important to consider the length you require and ensure that you order the correct size. Custom-length hoses can be a great solution to ensure a perfect fit for your application.
