EVIL ENERGY 4AN Fuel Line Kit 10ft - Durable Nylon Braided Fuel Hose

In this review the EVIL ENERGY 4AN Fuel Line Kit is evaluated for enthusiasts and mechanics who need a reliable, compact fuel hose run for performance or replacement projects. The single biggest reason to consider this kit is its construction: a CPE rubber inner tube reinforced with 304 stainless steel wire and a nylon outer braid that delivers a balance of flexibility and strength suitable for fuel, race gas, oil, and transmission fluid. The review focuses on build quality, ease of assembly, and real-world compatibility for typical automotive installations.

Key Features

• Size: The 4AN inner diameter of 0.22 in and outer diameter of 0.43 in with a 10 ft length provides enough reach for most small fuel routing jobs without excessive bulk.
• Pressure Rating: The hose offers a working pressure of 750 psi and a burst pressure of 2250 psi, which gives confidence for many aftermarket fuel system setups.
• Temperature Range: Rated from -22F to 248F, the hose remains usable across a wide range of ambient and underhood temperatures for street and track use.
• Construction: A CPE synthetic rubber inner with a layer of 304 steel wire and nylon outer braid gives durability and abrasion resistance while maintaining flexibility for routing.
• Compatibility: The kit is compatible with fuel, race gas, oil, and transmission fluid, making it versatile for different fluid needs in performance builds.
• Fittings: Aluminum alloy hose fittings keep connections lightweight and corrosion resistant when properly installed.

Who It's For

This kit is aimed at DIY mechanics, track-day racers, and hobbyists who need a compact, resilient 4AN fuel hose run for aftermarket carburetor, regulator, or fuel pump installations. The 10 ft length and modest ID work well for smaller engines or when multiple bends and runs are required.

Those building high-pressure professional fuel systems requiring specialized PTFE or aviation-rated hoses, or users who need factory-specific OEM fittings, should look elsewhere. Also, installers who dislike trimming and assembly should note that proper attachment of fittings takes some care.

Pros & Cons

Pros

• High-quality materials provide strong resistance to abrasion and typical fuel system stresses.
• Good working and burst pressure ratings suitable for most aftermarket fuel setups.
• Flexible 10 ft length makes routing easier in tight engine bays and custom installations.
• Customers report the kit is easy to assemble and offers good value for money.

Cons

• Some users report occasional difficulty getting fittings to attach properly, so careful installation is required.
• The 0.22 in ID may not suit high-flow applications that demand larger inner diameters.
