What You'll Learn
Cutting and crimping
Cutting:
Before cutting, ensure you have the right tools for the job. It's recommended to invest in a good tube cutter to make clean, square, and burr-free cuts. This will help ensure a proper fit when assembling the new fuel line. Start by removing the existing fuel line from your vehicle. Take note of the routing and length of the original fuel line, as this will be your template for the new one. Remove all the fittings attached to the line, as you'll be reusing some of them.
When cutting the new fuel line, use the original line as a guide to measure and mark the required length. Cut the new fuel line to the exact size, ensuring it matches the original line's length. It's important to work with precision to avoid any discrepancies that could affect the performance of your vehicle.
Crimping:
Before crimping, ensure that your new fuel line is properly aligned and "bottomed out" on the fittings. This means making sure the line is fully inserted and seated correctly in the fittings. If the line is not bottomed out, your measurements may be thrown off, resulting in a line that is too long or too short.
Once your fuel line is properly positioned, it's time to crimp. Grab your ferrule crimping tool, typically a 1/2" size for fuel lines. Place the tool over the ferrule you want to crimp and start screwing the plastic knob in a clockwise direction until the ferrule is securely crimped. This process creates a strong and leak-proof connection between the fuel line and the fittings.
It's worth noting that crimping tools and techniques may vary slightly depending on the specific type of fuel line and fittings you're working with. Always refer to the manufacturer's instructions or seek guidance from experienced professionals when in doubt.
Additionally, consider the type of tubing you'll be using. Plastic-coated steel tubing, for example, is more expensive but significantly easier to bend and work with. Practising on some extra tubing can help you perfect your technique before tackling the final assembly.

Using high-quality materials
When making a custom fuel line, it is important to use high-quality materials to ensure safety and durability. Using low-quality materials can end up costing you extra time and money.
For instance, the latest convoluted PTFE (polytetrafluoroethylene) fuel hose from Earl's is considered a good option for a custom fuel line. The PTFE is impregnated with carbon, which makes the inner liner a darker colour. This carbon addition makes the material conductive, preventing static electricity discharge. This material is used in all new OE production cars as it is impervious to all fuels and additives. It also offers a good vapour barrier, preventing fuel evaporation through the fuel line.
Another option is the TechAFX PTFE hose, which is also carbon-impregnated but not convoluted. This type of hose requires a larger bend radius due to its stiffer nature. The Ultra-Pro hose is another choice, offering durability and longevity. However, it is more expensive, with a 20-foot length costing over $180.
When it comes to tools, investing in a good tube cutter is essential. A tube cutter helps achieve square and burr-free cuts, making it easier to work with the tubing. Additionally, consider getting extra tubing to practice on and perfect your cutting and bending techniques. Practising on tubing flares is also recommended.

Choosing the right tools
When it comes to choosing the right tools for crafting a custom fuel line, there are several factors to consider. Firstly, it's essential to use high-quality materials to ensure the safety and durability of the fuel line. Using low-quality materials can lead to potential hazards and additional costs in the long run.
For those who prefer to purchase a ready-to-install fuel line assembly, there are options available in the market, such as the latest offering from Earl's, which features a convoluted PTFE (polytetrafluoroethylene) fuel hose. This material, similar to Teflon®, is infused with carbon, making it conductive and eliminating the risk of static electricity discharge. It is also impervious to fuels and additives, providing a reliable vapor barrier.
However, if you intend to create a custom fuel line, investing in the right tools is crucial. A good tube cutter is essential for making precise, square, and burr-free cuts. Additionally, consider purchasing extra tubing to practice your cutting and bending techniques. Mark the tube at regular intervals to better understand how much the tube will bend. The routing of the fuel line is often considered the most challenging part of the process. Using a plastic-coated steel line can make bending significantly easier, although it tends to be more expensive.
For those working with fittings, a Mastercool kit can be useful for creating barbs that retain the hose during routing. It is important to note that you should not go all the way with the die, leaving the barb slightly rounded instead of sharp and flat. Additionally, companies like Inline Tube and Classic Tube offer custom stainless steel brake lines that can be purchased for specific classic cars.
Finally, for those seeking a more hands-off approach, companies like LinesToGo offer custom-built fuel lines. They provide directions and tools to help you create your own fuel line or offer a complete installation service to meet your specific requirements.

Measuring and marking
First, ensure you have the right tools for the job. It is recommended to have a good tube cutter, which makes a significant difference in achieving a square and burr-free cut. Additionally, having extra tubing to practice on is a good idea. Mark this practice tubing in 1" increments to get a sense of how much the tube will bend. Practising on the tube flares will also help you perfect your technique.
Next, remove the existing fuel line from your vehicle. Take precautions to ensure the line is free of any fuel or gas residue to avoid any safety hazards. Once the line is removed, carefully take off all the existing fittings attached to it and set them aside. You will be reusing these fittings, except for the ferrules and the fuel line itself.
Now, it's time to measure and mark the new fuel line. Use the original bare fuel line as a template. Measure its total length, and then cut your new fuel line to the exact same size. It is crucial to be precise in your measurements to ensure a proper fit. Mark the new fuel line accordingly, indicating the exact cut points.
After marking the new fuel line, you can begin cutting it to size. A tube cutter will help you achieve a clean, square cut. Take your time with this step, as accurate cutting is essential for a well-fitting fuel line. Once you're done cutting, double-check the length to ensure it matches the original fuel line.
In conclusion, measuring and marking are critical steps in creating a custom fuel line. By taking careful measurements, marking the tubing accurately, and practising your cutting technique, you can ensure a precise fit for your new fuel line. Remember to use high-quality materials and follow all safety precautions throughout the process.

Bending and routing
First, you need to determine the route of your new fuel line. This involves carefully planning the path the fuel line will take from the fuel tank to the engine. Consider the location of the fuel tank, the engine, and any obstacles or tight spaces the fuel line needs to navigate through. This step is crucial as it ensures that your new fuel line fits perfectly and functions properly.
Next, you should purchase or create a fuel line that is slightly longer than your intended route. This will give you some flexibility during the bending and installation process. It is recommended to use high-quality materials, such as the latest PTFE (polytetrafluoroethylene) fuel hoses, which offer better durability, safety, and vapour barrier properties.
When you are ready to start bending, mark the tube at regular intervals (about 1-inch increments) to help you visualise and control the bend. Practice bending on extra tubing first if you can, to perfect your technique and not risk damaging your final fuel line. The use of a tube cutter is also recommended to achieve square and burr-free cuts.
The actual bending process can be physically demanding, and it is important to work with caution and patience. Take your time and avoid forcing the tube to bend abruptly, as this may cause kinks or damage. If you are using a rigid material for your fuel line, consider the bend radius required and use appropriate tools or equipment to achieve the necessary bends without compromising the integrity of the tube.
Finally, once you have successfully bent the fuel line to match your desired route, it's important to double-check all your measurements and fittings before finalising the installation. Ensure that the fuel line is secure, properly connected, and free of any leaks.
Remember, creating a custom fuel line can be challenging, and it is always recommended to seek professional guidance or assistance if you are unsure about any aspect of the process.
