8AN Braided Fuel Line Kit 12ft Nylon - Durable High-Pressure Hose

In this review the EVIL ENERGY 8AN Fuel Line Kit is evaluated for drivers and fabricators who need a versatile, high-pressure braided hose for fuel, oil or coolant routing. The single biggest reason to consider this kit is its combination of a CPE rubber inner hose with 304 steel wire and a nylon outer braid, which delivers a robust hose assembly rated for a 750psi working pressure and wide temperature range, making it suitable for many under-hood and cooler applications.

Key Features

• Versatile application: The kit can be used as a transmission oil cooler line, fuel return or supply line, coolant hose, vacuum or turbo cooler line, offering flexibility across projects.
• Durable construction: The hose uses a CPE rubber inner core with a 304 steel wire layer and nylon braid, providing abrasion resistance and durability under engine-bay conditions.
• Fitting selection: The package includes six swivel hose ends (two straight, two 45 degree, two 90 degree) which simplifies routing and fitting to existing components.
• Pressure and safety margins: With a maximum working pressure of 750psi and a bursting pressure of 2250psi, the hose offers a reliable safety margin for higher-demand systems.
• Temperature range: Rated from -22F to 248F, the hose handles a broad range of operating environments without rapid degradation.

Who It's For

This kit is ideal for automotive enthusiasts, mechanics and small fabrication shops that need an all-purpose 8AN line for fuel systems, coolers, or oil feeds. The included swivel fittings and 12ft length make it convenient for retrofits and custom plumbing where flexibility and a black-on-black appearance matter.

Those working with extreme temperatures beyond the stated range or requiring stainless steel fittings rather than aluminum should look elsewhere, as the fittings provided are aluminum alloy and the hose temperature limits are specified.

Pros & Cons

Pros

• Solid construction with CPE inner and 304 steel wire braid improves longevity under typical automotive fluids.
• Good value with a 12ft length and a mix of straight and angled swivel fittings for adaptable routing.
• High working and bursting pressures provide confidence for higher-pressure applications like return lines or oil feeds.

Cons

• Some users report challenges getting fittings to attach perfectly, so careful assembly and inspection are required to avoid leaks.
• Fittings are aluminum alloy, which may not suit every high-end racing or marine application that prefers stainless fittings.

Specifications

Our Verdict

The EVIL ENERGY 8AN 12ft braided fuel line kit is a practical, cost-effective option for car builders and technicians who need a flexible, durable line for fuel, oil or coolant routing. Its construction and pressure ratings make it a strong choice for general automotive and performance plumbing, though installers should take care during assembly and may prefer different fittings for extreme applications.

Frequently Asked Questions

Can this hose be used with diesel or race gas?
Yes, the nylon and stainless steel braided hose with a CPE inner is compatible with diesel, race gas and many automotive fluids.

Are the fittings reusable?
The kit fittings are aluminum alloy swivel ends intended for assembly; reuse is possible if inspected for damage but fresh fittings are recommended for critical systems.

Will 12 ft be enough for a vehicle install?
12 ft covers many installations and cooler lines, but longer runs or multiple circuits may require additional hose or a second kit.
