EVIL ENERGY 6AN Fuel Line Kit - 10ft Braided Nylon Fuel Hose

Our review of the EVIL ENERGY 6AN Fuel Line Kit finds it best suited for DIY mechanics and performance-minded installers who need a durable, visually tidy fuel or fluid line for custom plumbing. The single biggest reason to buy is the kit's balanced combination of a CPE rubber inner tube, 304 steel wire reinforcement and a nylon outer braid that delivers useful working pressure and broad chemical compatibility while still being relatively easy to route and assemble. Overall it performs like a shop-ready replacement hose for fuel, oil and transmission fluid runs.

Key Features

• Size: The 6AN inner diameter of 0.31in and outer diameter of 0.56in makes the hose suitable for common aftermarket fuel and oil plumbing and fits standard AN6 fittings.
• Length: The 10ft length provides enough hose for many single-run installations without the need to join sections, simplifying routing.
• Construction: The CPE rubber inner with a 304 steel wire layer and nylon braid gives a good balance of flexibility and abrasion resistance for engine-bay use.
• Pressure rating: A working pressure of 750psi and burst rating of 2250psi offers a safe margin for typical fuel and transmission fluid systems in street and light performance applications.
• Temperature range: Rated from -22F to 248F, the hose tolerates cold starts and typical engine-room heat without hardening or rapid deterioration.
• Compatibility: The hose accepts fuels, race gas, diesel, transmission fluid, oil and vacuum applications, reducing the need to buy different lines for different fluids.

Who It's For

This kit is aimed at home installers, track-day builders and small shops that need an economical, attractive AN6 braided hose for fuel, oil or transmission plumbing. The black and red finish makes it a good fit where appearance matters as well as function.

It is not aimed at extreme racing teams needing PTFE or purpose-built hose for consistently higher pressures, nor is it intended as a direct OE replacement where manufacturer-specific fittings or certifications are required.

Pros & Cons

Pros

• High perceived quality thanks to the braided nylon finish and steel wire reinforcement that resists kinking.
• Good value: the 10ft length and broad compatibility cover many jobs without extra purchases.
• Easy to route and install for typical custom plumbing tasks, with a flexible minimum bending radius.
• Aesthetically pleasing black and red option that reviewers noted looks good.

Cons

• Some users report concerns about long-term durability and abrasion damage in harsher conditions, so it may need protective routing in demanding installations.
• Not a substitute for PTFE-lined hoses where extreme chemical resistance or ultra-high pressure is required.
