Connectors: Use barbed or brass fittings, or compression sleeves
When connecting a rubber fuel line to a nylon fuel line, it is essential to use the correct connectors to ensure a secure and leak-proof joint. There are several options available for connectors, including barbed fittings, brass fittings, and compression sleeves.
Barbed fittings, also known as barbed connectors, are commonly used to join fuel lines. They are designed with raised ridges or barbs that grip the inner surface of the hose, creating a tight seal. When using a barbed fitting, it is important to slide the hose onto the fitting carefully to avoid damage. Some users prefer to use a compression fitting over the nylon that goes to a barb to connect the rubber hose for added security.
Brass fittings, such as brass barbed splice fittings, are specifically designed for hard nylon lines. To install a brass fitting, it is recommended to heat the fitting in boiling water or with a hair dryer to soften the nylon line and allow for a secure connection. This method helps prevent the fitting from sucking the heat out of the plastic line, causing it to cool and shrink too quickly.
Compression sleeves, like the 1/4" brass compression sleeve, can be used in conjunction with clamps to create a secure connection. In this method, the compression sleeve is inserted into the nylon line, which is then pushed into the rubber hose and clamped down using a fuel hose clamp.
It is important to note that preparation is key when connecting fuel lines. Before beginning the installation, ensure you have the correct connectors, clamps, and tools. Measure and cut the fuel lines to the appropriate length, and always wear safety gloves to protect your hands. Additionally, inspect your connectors for any cracks or damage before use.
By following these instructions and using the appropriate connectors, you can confidently connect a rubber fuel line to a nylon fuel line, ensuring a reliable and leak-proof joint.

Hose clamps: Secure the connection with multiple clamps
Hose clamps are an essential component in securing the connection between fuel lines and their fittings. They are designed to prevent leaks, vibrations, and movement of hoses, ensuring efficient fluid flow and system integrity. When connecting a nylon fuel line to a rubber one, hose clamps are necessary to secure the two lines together.
To ensure a tight and secure connection, multiple hose clamps may be required, depending on the size and type of fuel lines being used. It is important to select hose clamps made from durable materials such as stainless steel or aluminum, which offer corrosion resistance and long-term durability. The clamps should also be the appropriate size and style to accommodate the diameter and type of hoses being connected.
Worm-drive clamps are the most common type of hose clamp. They consist of a stainless steel band with a screw mechanism that tightens the band around the hose, providing consistent pressure and forming a secure and leak-proof seal. Ear clamps, or Oetiker clamps, are another option. These are tightened by crimping the "ear" or tab on the clamp, creating a permanent, non-adjustable, and tamper-proof seal.
When securing the connection between nylon and rubber fuel lines, it is crucial to follow the proper steps. First, measure and cut the fuel lines to the required length using a sharp utility knife or hose cutter. Then, use a heat gun to soften the nylon fuel line before sliding it onto the rubber fuel line. Ensure that the connection is snug but not too tight, as this could lead to leaks or damage to the fuel line. Finally, secure the connection with multiple hose clamps, tightening them appropriately to create a tight seal and prevent fuel leaks.

Cutting: Use a knife or cutter to cut the lines to the required length
Cutting the lines to the required length is a crucial step in the process of connecting nylon to rubber fuel lines. It requires precision and the right tools to ensure a proper fit and prevent leaks.
First, you must measure the length of the old fuel line to determine the required length of the new line. Mark the desired length on the new line using a measuring tape or ruler and a pencil or marker. It is important to choose fuel lines with the correct diameter and wall thickness for your specific application.
When it comes to the cutting tool, it is recommended to use a sharp utility knife or a hose cutter for a clean cut. A razor blade or a tubing cutter can also be used for a very sharp cut, ideal for precise applications. These tools provide the necessary precision to cut the lines without crushing or deforming them. Hacksaws, for instance, are not suitable as they can crush or deform the line. Always handle blades with care and wear safety gloves to protect your hands from potential cuts or abrasions.
For curved applications, use a utility knife or razor blade to cut along the inside of the curve, creating a gradual taper. Cut at a 45-degree angle to facilitate easier insertion into fittings and smooth any rough edges with fine-grit sandpaper if needed. Apply even pressure throughout the cut to prevent the line from bending or buckling.

Heat: Use boiling water or a heat gun to soften the nylon
When connecting a nylon fuel line to a rubber one, you will need both the nylon and rubber fuel lines, hose clamps, a utility knife or hose cutter, and safety gloves. The process can be challenging, but with the right tools and preparation, it can be done successfully.
One crucial step in the process is softening the nylon fuel line. This can be done using a heat gun or boiling water. If you choose to use a heat gun, be cautious and follow safety precautions, especially when working near the fuel tank. The heat gun should be used to soften the nylon fuel line, making it easier to slide onto the rubber fuel line. It is important to ensure that the connection is snug but not too tight to avoid leaks or damage to the fuel line.
Boiling water is another method to soften the nylon fuel line. Soak the nylon in water at 180-185°F (or 70-90°F if using Orcosoft NQ 150™), and then immediately pull the nylon back to its original length and let it cool. This process can be repeated if needed. However, some people have found that boiling water alone may not be sufficient to soften the nylon enough, and additional heat from a hair dryer or heat gun may be necessary.
When using boiling water or a heat gun, it is important to be cautious and avoid overheating the nylon, as this could affect its properties. The ideal temperature range for softening nylon is above its glass transition temperature (Tg) but below its melting point. For nylon 6, the melting point is around 216°C, so be sure not to exceed this temperature.
Additionally, when softening nylon with heat, it is crucial to consider the environment you are working in. Avoid areas with fuel vapors or open flames, as they can pose safety hazards. Always work in a well-ventilated area and follow safety guidelines for handling fuel lines and heat sources.
