What You'll Learn
A 6-foot roll of fuel line is common for basic fuel systems
A 6-foot roll of fuel line is a common length for basic fuel systems on go-karts. This length is typically used to plumb the fuel system, including the catch cans, main fuel line, in-tank plenum, and overflow bottles. It is important to note that the fuel line should be replaced each season to prevent excessive hardening, which can lead to cracking, pinching, fraying, or air leaks.
When choosing a fuel line for your go-kart, consider the type of fuel system you have. If you have a high-flow fuel system or one that uses return lines, you may need more than 6 feet of fuel line. Additionally, the size of the fuel line itself is important to ensure optimal engine performance. If the line is too small, an external fuel pump may not receive enough fuel.
To address this, many aftermarket fuel pumps will list the required fuel line sizes. If your pump does not specify the line size, you can refer to sizing tables or guidelines provided by manufacturers or experts. As a general rule, it is recommended to keep the pump below the tank's outlet and as close to the tank as possible to ensure gravity feeds fuel to the pump effectively.
The fuel line material is also an important consideration. Clear, flexible polyurethane-based plastic fuel lines are commonly used in go-karts. This material is ideal for racing kart fuel systems as it allows for visual inspection and can help prevent scratches on components like tie-rods and brake/throttle cables.
In summary, a 6-foot roll of fuel line is a standard length for basic go-kart fuel systems, but the specific needs may vary depending on the fuel system configuration and performance requirements. Regular maintenance and proper sizing of the fuel line are crucial to ensure the optimal operation of your go-kart's engine.

Use more than 6 feet for high-flow fuel systems
For a basic go-kart fuel system, a 6-foot roll of fuel line is typically sufficient for the main fuel line, catch cans, in-tank plenum, and overflow bottles. However, if you have a high-flow fuel system or one that uses return lines, it is recommended to use more than 6 feet of fuel line.
The extra length is necessary to accommodate the increased fuel flow and the potential use of return lines in the system. High-flow fuel systems are designed to deliver a greater volume of fuel to the engine, and as a result, require a larger or longer fuel line to handle the increased flow effectively. Return lines are used in some fuel systems to circulate unused fuel back to the tank, which also requires additional fuel line length.
By using more than 6 feet of fuel line, you can ensure that the fuel system has the necessary capacity and flexibility to handle the high-flow demands. This helps maintain proper fuel pressure and flow rate, ensuring optimal engine performance. Additionally, the longer fuel line can provide more routing options, allowing for a more efficient and neat installation.
It is also important to consider the material and quality of the fuel line when dealing with high-flow fuel systems. A flexible, durable, and resistant fuel line is crucial to withstanding the increased fuel flow and pressure. Polyurethane-based plastic fuel lines, for example, offer flexibility and clarity, making them a popular choice for go-kart fuel systems.
Finally, remember to replace your fuel line regularly, especially if you are using a high-flow fuel system. Over time, the fuel line components can harden, crack, or become damaged, leading to leaks and other issues. Regular maintenance, including replacing the fuel line, will help ensure the reliability and performance of your go-kart's fuel system.

Prevent issues by replacing the fuel line each season
Go-kart fuel systems typically require a 6-foot roll of fuel line to plumb a basic setup. However, if you have a high-flow fuel system or one that uses return lines, you may need more than 6 feet.
While the frequency of fuel line replacement depends on various factors, including the type of fuel used and the maintenance routine, it is generally recommended to replace the fuel line on your go-kart at the end of each season as a preventive measure.
Over time, the fuel line components can harden, making them susceptible to cracking, pinching, fraying, or air leaks. By replacing the fuel line regularly, you can avoid these issues and maintain the optimal performance of your go-kart.
Additionally, certain types of fuel can leave residue or cause gumming, which can lead to blockages in the fuel line. Lower octane fuels, for example, tend to leave more residue, requiring more frequent cleaning or replacement of the fuel line.
Therefore, by replacing the fuel line each season and using fresh, high-quality fuel, you can prevent potential issues and ensure a smooth and reliable performance from your go-kart. This proactive approach can save you time and money in the long run, allowing you to focus on enjoying your go-karting experience without unexpected breakdowns or maintenance hassles.

Clear fuel lines are ideal for racing karts
For racing karts, clear fuel lines are the ideal choice for several reasons. Firstly, they are made from flexible polyurethane-based plastic, which offers a good balance between durability and pliability. This material is also caustic chemical and UV-ray resistant, ensuring that the fuel line remains intact even when exposed to various chemicals and sunlight. The clear colour of the fuel line is advantageous as it allows for easy inspection and detection of any fuel leaks or blockages. This can help racers identify potential issues before they become bigger problems, ensuring the fuel system runs smoothly and reducing the risk of mid-race breakdowns.
Additionally, the clear fuel lines are available in a variety of lengths, ensuring they can accommodate different kart designs and fuel system configurations. The standard length required for a basic fuel system is approximately 6 feet, but for high-flow fuel systems or those with return lines, longer lengths may be necessary. The inner and outer diameters of the tubing are also important considerations, with standard sizes being 1/4" Outer Diameter (OD) and 3/16" Inner Diameter (ID).
Clear fuel lines are not just functional but also help protect other components of the kart. They can be used for fuel catch cans and radiator overflow bottles, preventing fuel or coolant spills that could damage the kart or pose a safety hazard. The clear lines also help prevent scratches on sensitive components such as tie-rods and brake/throttle cables, as their flexibility reduces the risk of abrasion.
To maintain the performance and integrity of clear fuel lines, it is recommended to replace them regularly, ideally at the end of each racing season. Over time, the fuel line components can harden, leading to cracking, pinching, or fraying, which may result in air leaks. Therefore, regular replacement ensures that the fuel system remains in optimal condition, reducing the risk of performance issues or unexpected breakdowns during races.
