What You'll Learn
Using compression fittings for plastic fuel lines
Compression fittings are a great way to deal with plastic fuel lines, especially on older vehicles. They are a good solution when you need to cut and splice a fuel line, for example, when dealing with rust or a small fire that has damaged the line.
Compression fittings allow for a degree of error in the cut, as they can still seal the line even if it is cut a few degrees off-square. This is an advantage over other methods, such as flaring, which can be difficult and messy.
When using compression fittings with plastic fuel lines, it is important to consider the type of fitting and line you are using. Some common brass compression fittings are designed for use with soft metals like copper and may not be ideal for plastic lines. You can get fittings with plastic ferrules that are designed to crush/seal correctly around plastic or nylon lines. It is also important to ensure that the line you are using is rated for fuel and can handle the pressure. For example, rubber fuel hose is not recommended for pressures above 10 psi, while fuel injection systems can have pressures of 40-70 psi.
To install a compression fitting on a plastic fuel line, you can follow these steps:
- Cut the plastic line with a suitable cutter, ensuring it is straight.
- Softened the end of the nylon line with hot water.
- Push the softened end of the nylon line onto the barbs of the fitting. The nylon will push on very hard, and when it hardens, it will create a strong seal.
- Allow the nylon to harden and you're good to go! No clamps or additional tools are needed.
This method provides a safe and effective way to splice plastic fuel lines using compression fittings.

Replacing metal fuel lines with rubber lines
First, assess the condition of your existing metal fuel lines. If they are heavily rusted or damaged, it is best to replace them entirely with new metal lines or opt for rubber lines. If the damage is localized, you can choose to cut out the affected sections and splice in new rubber lines.
When splicing in rubber lines, it is crucial to ensure a secure connection between the metal and rubber sections. One common method is to use barbed fittings and clamps. However, some people dislike this method due to the potential for leaks. An alternative is to flare the ends of the metal line and then slip the rubber hose over, securing it with clamps. This creates a tighter seal and reduces the risk of slippage.
It is important to select the appropriate type of rubber hose for your application. Choose a high-pressure, diesel-rated hose if your vehicle uses diesel fuel. For biofuels, you can find specific hoses designed to handle these types of fuel. Additionally, consider the inner diameter (I.D.) of the hose to ensure it matches the line it is replacing. A smaller I.D. may restrict fuel flow, while a slightly larger I.D. is typically not an issue.
Finally, always double-check your connections and keep an eye on your repairs for any signs of leaks. Leaking fuel can be a safety hazard and can cause damage to your vehicle. Regularly inspect your fuel lines and consider using push-lok fittings, which are known for their reliability and ease of maintenance.
In conclusion, replacing metal fuel lines with rubber lines is a viable option, especially for older vehicles or when dealing with localized leaks. Rubber lines offer flexibility and ease of installation, but it is crucial to use the correct type of hose and ensure secure connections to prevent leaks.

Using a repair kit for plastic lines
Repair kits are available for fuel lines made of steel or plastic tubes with an outside diameter of 8 or 10 mm. These kits can be used to repair smaller defective spots on fuel lines, such as rusted areas, broken plugs, or junctions of different materials. When using a repair kit, it is important to follow safety regulations for handling fuels.
- Identify the defective spot on the fuel line. Turn off the fuel supply and relieve the pressure in the line before beginning any repair work.
- If the plastic fuel line is broken or cracked, use a repair kit with epoxy putty specifically designed for plastic fuel lines. Make sure the area is clean and dry before applying the epoxy.
- Use your fingers to cover the entire defective area with the epoxy putty. Smooth out the epoxy to create an even line where the glued part ends.
- Let the epoxy set for at least 30 minutes, or longer depending on the manufacturer's instructions.
- Once the epoxy is dry, reconnect the fuel line to the gas tank and other components.
- Prime the fuel pump and start the engine. Carefully inspect the repair work for any leaks while the engine is running.
It is important to note that this is a general guide, and specific instructions may vary depending on the type of repair kit and the vehicle's make and model. Always refer to the manufacturer's instructions and safety guidelines when working with fuel lines.
In addition to repair kits, some other methods for splicing plastic fuel lines include using compression fittings, brass barbed splices, or automotive fuel line clamps. However, it is important to use caution and consult with automotive professionals or mechanics to ensure safe and effective repairs.

Using metal tubing for low-pressure applications
When it comes to using metal tubing for low-pressure applications, there are several options to consider. Metal tubing is commonly used for fuel lines, and the specific type of metal chosen depends on various factors such as strength, corrosion resistance, thermal conductivity, and cost. Here are some of the commonly used metals for low-pressure applications:
Steel Tubing
Steel tubing is widely known for its high strength and durability, making it suitable for fuel lines. It is highly malleable, allowing for easy bending to follow the typical routing through a vehicle. Steel tubing is also relatively easy to flare, creating reliable, leak-free connections. However, steel is susceptible to corrosion, especially when exposed to moisture and road salt, so regular maintenance and protective coatings may be necessary to prevent rust.
Stainless Steel
Stainless steel is a harder material than regular steel and offers better corrosion resistance. It is often considered a more durable alternative, but it tends to be more costly and can be more challenging to work with if the right tools are not available.
Copper
Copper exhibits good thermal conductivity, which helps dissipate heat generated during braking. However, copper is softer than steel and stainless steel, so it may require thicker walls for high-pressure applications. Copper is generally more expensive than regular steel but may be less costly than stainless steel. Over time, copper can develop a patina, which may affect its appearance.
Aluminum Tubing
Aluminum is another popular choice for fuel lines. It is easy to bend, cut, and flare, and it can even be polished to a high sheen. However, it can be challenging to get it perfectly straight, especially when purchased in rolls. The standard 45-degree double flare method is not commonly used with aluminum due to its softness. Instead, the 37-degree single flare method is typically used, requiring tube sleeves and tube nuts to ensure a quality seal.
Copper-Nickel Alloy Tubing
This type of tubing, such as Earl's Easy-Form tubing, combines the benefits of copper and nickel. It is strong like steel but much easier to cut, bend, and flare, similar to aluminum. It is highly resistant to rust and corrosion and is approved for use on hydraulic brake systems and fuel lines.
When using metal tubing for low-pressure applications, it is important to consider the specific requirements of your project and select the metal that best suits your needs in terms of strength, corrosion resistance, ease of use, and cost. Additionally, proper techniques, such as flaring and bending, should be employed to ensure reliable and leak-free connections.
