What You'll Learn
Compatibility with fuel pumps and fuel systems
Universal fuel line kits are designed to offer flexibility and are generally compatible with a wide range of fuel pumps and systems. For example, the Tanks Inc. universal fuel line kit provides all the necessary fittings to plumb a FI-Tech system and most fittings required for systems with external fuel regulators, such as MSD Atomic, Holley Terminator, and FAST EZ-EFI. This compatibility allows for easy integration with various fuel pump and regulator setups, making it a versatile option.
Additionally, some universal fuel line kits are specifically designed for custom fuel systems, ensuring the right fit and performance. Summit Racing Equipment, for instance, offers a range of fuel line kits to cater to diverse fuel system configurations. These kits often include AN fuel lines and fittings, filters, regulators, distribution blocks, pumps, and rails, providing a comprehensive solution for custom plumbing requirements.
When it comes to fuel pumps, compatibility is crucial for ensuring optimal performance and easy installation. EVIL ENERGY, a renowned brand in the fuel system space, offers universal fuel line kits that are compatible with LS swap EFI systems. Their kits include a high-flow fuel pump with a capacity of 300LPH, a 10-micron fuel filter, and durable fuel lines made from CPE or PTFE. This compatibility ensures that the fuel line kit can be effectively utilized with LS swap EFI setups, enhancing the vehicle's fuel delivery system.
It is important to note that while universal fuel line kits strive to provide broad compatibility, there may be exceptions or specific requirements for certain vehicles or fuel systems. For instance, in the case of an LS engine, the universal fuel line kit may not include fuel rail adapter fittings, necessitating additional considerations or adaptations. Therefore, it is always advisable to refer to the manufacturer's instructions and specifications to ensure complete compatibility with your fuel pump and fuel system.

Hose length and type
When it comes to hose length and type, there are a variety of options available for universal fuel line kits. The length of the hose will depend on the specific application and the distance between the fuel tank and the engine. Common lengths for fuel hoses include 5, 10, 12, 16, 20, and 25 feet. It's important to choose a hose that is long enough to reach the necessary components, with some flexibility for manoeuvring.
Different types of hoses are available, such as nylon braided, rubber, or Teflon/PTFE-lined hoses. Nylon braided hoses, for example, are known for their durability and ability to withstand high pressure and temperature variations. They are constructed from high-quality nylon and synthetic rubber, ensuring safety and reliability. Rubber hoses, on the other hand, are more affordable and suitable for standard parts, available in both low and high-pressure options.
Teflon/PTFE-lined hoses are designed to prevent the escape of fuel vapour, making them suitable for use inside and outside the car. They feature an outer stainless-steel over-braid and come in different sizes, such as dash 6 (-6) or dash 8 (-8), which relate to the hose bore and the thread of the fitting. This type of hose also has low internal friction, making it ideal for long lengths, and its small outside diameter makes it a good choice for tight installations.
Another option is the push-on hose, which is low-cost and easy to install. It can be used on standard parts without any modifications and is available in various internal diameters, including 6mm, 8mm, 10mm, 12mm, 15mm, and 19mm. Push-on hoses can be secured with hose clips or swaged on, but they are not recommended for use inside the car as they allow vapour and fumes to escape.
Some fuel line kits may also include a push lock hose, which is flexible, lightweight, and compatible with various fuels and additives. This type of hose is easy to assemble and can be used with reusable push lock hose ends, making it suitable for most fuel and oil systems.

Fittings and adapters
First and foremost, it's important to note that the fittings included in a universal fuel line kit will depend on the specific kit you've purchased. Some kits may provide fittings compatible with specific fuel pump brands, such as Tanks Inc., while others offer fittings suitable for a range of fuel pump and fuel system configurations. For example, the Tanks Inc. kit includes all or most fittings needed to plumb a FI-Tech system and many fittings for systems with external fuel regulators like MSD Atomic, Holley Terminator, and FAST EZ-EFI.
The fittings in your kit may vary in shape and angle. Some kits offer straight fittings, while others provide 45-degree fittings. These angles are important to consider as they dictate how your fuel lines will be routed and connected. 45-degree fittings, for instance, can be useful when you need to access the fuel pump in a recessed bowl, providing easier accessibility.
Universal fuel line kits typically include a variety of adapters to facilitate connections between different types of fuel lines and system components. For example, the iBuildRacecars.com 6AN Flex Fuel Line Kit comes with straight fittings and quick-connect adapters to connect the fuel line to OEM fuel hard lines and flex fuel sensors. These adapters vary in size and angle, ensuring you can make the necessary connections in your fuel system.
When using fittings and adapters, it's crucial to follow the manufacturer's instructions and take the necessary precautions. Before making any final cuts or installations, it's recommended to mock-up all fittings and hose lengths to ensure a proper fit. Additionally, after trimming the hose, inspect the line for any debris or residue caused by the cutting process to prevent contamination in the fuel system.
Lastly, depending on your specific fuel system setup, you may need additional fittings or adapters not included in the universal fuel line kit. For instance, if you have an LS engine, you may require separate fuel rail adapter fittings to complete the installation. Always refer to the kit's compatibility information and your fuel system's requirements to determine if any supplementary fittings or adapters are needed.

Custom fuel systems and plumbing
- Planning and Diagramming: Before starting, create a simple diagram of where you intend to mount the various components. This visualization helps identify potential issues and ensures that all necessary parts are accounted for.
- Hose Selection: The hose is the vital link that joins all components together. Choose a hose that suits your system's pressure requirements and intended use. For example, a Teflon/PTFE-lined hose can be used inside and outside the car, preventing the escape of fuel vapour and eliminating stale fuel smells.
- Fittings and Accessories: Select fittings and accessories that match your hose and system requirements. Brands like Earl's offer high-quality components, including hoses, fittings, and plumbing accessories. Ensure the fittings are compatible with your hose and consider factors such as pressure ratings, especially when dealing with fuel injection systems.
- Fuel Tank Considerations: If your car has a replacement tank, it may have a built-in regulator, common in single-point injection cars. If the car doesn't run properly after plumbing, try clamping the return pipe. If it runs well, add a regulator to the return line to pressurize the fuel system.
- Heat Considerations: Keep hoses away from extreme heat sources. If they must be placed near heat, use insulating panels and fire-resistant sheathing. Do not run fuel lines near hot fluid lines to avoid issues like hot fuel, low power, or vapour lock.
- Assembly and Installation: During assembly, avoid over-tightening hose ends onto adapter fittings. Use the appropriate wrenches designed for this purpose. For metal lines, consider using a double flare tool and bendable lengths of hard metal line, transitioning to flexible lines with the appropriate fittings.
- Fuel Sampling Kits: For cars used in rallying, consider adding a fuel sampling kit to the system. These can be push-on hose types or threaded connections. The kit includes a dry break coupling that allows fuel to flow when the drain hose is connected.
- Fuel Line Kits: Consider using fuel line kits from brands like Summit Racing, which offer a wide variety of options to hook up your custom fuel system. These kits can include filters, regulators, distribution blocks, pumps, and rails, simplifying the plumbing process.
