There are indeed differences between gasoline and diesel fuel hoses, and it is important to use the correct type of hose for the relevant fuel to avoid damage and ensure safety. The American Boat & Yacht Council (ABYC) recommends Type B1 fuel hose for diesel-based applications and Type A1 for gasoline supply. Diesel fuel may cause certain types of rubber hoses to strip and break down over time, so it is important to use a hose that is rated for diesel fuel. For biodiesel, a higher-rated hose is required, and Teflon or PTFE hoses are recommended as they are resistant to most fuels. When purchasing a fuel hose, it is important to look for one with the correct SAE specifications and to ensure that it meets government emissions regulations, such as CARB certification, to guarantee safety and avoid legal issues.

Hose materials
For diesel fuel, it is generally recommended to use a hose that is specifically marked as "diesel-rated" or "diesel-specific". These hoses are made of materials that can withstand the properties of diesel fuel and are less likely to be affected by fuel additives. Some sources mention using a hose with an R10 rating for diesel, while others suggest a 30R9-rated hose, especially for biodiesel fuel. It is also important to ensure that the hose is compatible with the age of your vehicle; pre-1986 vehicles may require a hose made of modern synthetic materials.
For gasoline fuel, the most common fuel line is R6-rated. Type A1 hose is also recommended for gasoline supply by the American Boat & Yacht Council (ABYC). Regular fuel lines are typically compatible with gasoline, and CARB-certified fuel hoses are recommended for better fuel economy and resistance to seepage.
In addition to diesel-specific and gasoline-specific hoses, there are also fuel hoses designed for high-ethanol fuels and marine applications. For high-ethanol fuels, it is important to ensure that the hose can handle alcohol-blended fuels. Marine fuel hoses, on the other hand, need to meet specific requirements, such as fire resistance, and are usually marked with "USCG" (United States Coast Guard) certification.

Hose ratings
When choosing a fuel hose, it is essential to verify its compatibility with the specific fuel type you will be using. For diesel fuel, look for a hose marked "diesel" or "diesel-specific." Biodiesel, in particular, requires a hose with a higher rating, such as a 30R9 hose, to handle its unique characteristics. On the other hand, gasoline hoses typically carry ratings such as R6 or A1, indicating their suitability for gasoline applications.
The hose's intended application also plays a role in selecting the right hose. For example, a fuel injection hose is designed for fuel-injected engines, which operate at higher fuel pressures than carbureted engines. If your vehicle has a carbureted engine, a standard fuel hose is generally sufficient. Additionally, consider the age of your vehicle. For pre-1986 vehicles, modern synthetic materials may be required for rubber fuel hoses.
It is worth noting that some hoses are designed for specific industries or use cases. For instance, marine applications require fuel hoses that meet fire resistance standards set by the United States Coast Guard (USCG). These hoses are typically labelled as "marine fuel hoses" and bear the "USCG" marking. Similarly, the California Air Resources Board (CARB) has strict emissions regulations, and hoses that meet these standards are marked with "CARB," offering better fuel economy and resistance to seepage.
When purchasing a fuel hose, always refer to the SAE (Society of Automotive Engineers) specifications. These specifications ensure the hose's compatibility with the intended fuel type and application. Avoid hoses without clear SAE specifications, as they may not meet the required standards. By following these guidelines, you can ensure the safe and effective use of fuel hoses in your equipment.

Hose compatibility
For diesel fuel, it is generally recommended to use a hose that is specifically marked or rated for diesel. Diesel fuel contains additives and solvents that can break down certain types of rubber hoses over time, causing them to crack or disintegrate. To prevent this, look for a diesel-rated hose made from modern synthetic materials, such as the Gates RLA hose or the Goodyear R10 hose. If you are using biodiesel, a 30R9-rated hose is recommended, as standard diesel fuel hoses may not be compatible.
When using gasoline, the most common fuel line is the R6 hose. However, it is important to ensure that the hose is compatible with the specific type of gasoline you are using. For example, if you are using high-ethanol fuel, you will need a hose that can handle alcohol-blended fuels. Additionally, if your vehicle is fuel-injected, you will need to use a fuel injection hose rather than a standard fuel hose.
It is also important to consider the specific application of the hose. For example, if the hose will be connected to a fuel pump inside the gas tank, you will need a submersible in-tank fuel line that can resist breaking down when submersed in fuel. CARB-certified hoses are recommended as they resist seepage better and provide better fuel economy. For marine applications, look for a hose that meets USCG requirements for fire resistance, typically marked with "USCG" or "marine fuel hose" on the packaging.

Hose lifespan
The lifespan of a fuel hose depends on the type of fuel it carries and the material it is made of. Fuel hoses can be made of plastic, rubber, or metal. Hoses made of rubber are more susceptible to damage from the fuel they carry. Diesel fuel, for example, has been known to eat up, dry out, and crack rubber hoses. Gasoline, on the other hand, can cause rubber hoses to turn to mush.
The American Boat & Yacht Council (ABYC) recommends the Type B1 fuel hose for diesel-based applications, while the Type A1 hose is the best option for gasoline supply.
GoodYear, for instance, offers the R6 hose for gasoline, and the R10 hose, which is the only one they make that is rated for diesel.
Fuel hoses can last anywhere from 10,000 to 50,000 miles depending on their material composition. Metal fuel lines, for example, are more durable than rubber hoses and can withstand the harsh conditions of the engine. Therefore, it is important to inspect the hoses regularly to identify any repair issues before they become major problems.
In addition to the type of fuel and hose material, the lifespan of a fuel hose also depends on the engine's condition and usage. Engines that are properly maintained and operated within their design specifications will help extend the lifespan of the fuel hose. Conversely, engines that are subjected to harsh conditions, such as high temperatures and pressures, may reduce the lifespan of the fuel hose.
Furthermore, the lifespan of a fuel hose can be influenced by the quality of the hose and the accuracy of its installation. A higher-quality hose that is properly installed is likely to last longer than a lower-quality hose that is not installed correctly.
In summary, the lifespan of a fuel hose depends on various factors, including the type of fuel, hose material, engine condition, usage, quality, and installation. Regular inspection and maintenance of the fuel hose and engine can help extend its lifespan and ensure the safe and efficient operation of the vehicle.
