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

In this review the EVIL ENERGY 6AN Fuel Line Kit is assessed for motorists and DIY tuners who need a durable, flexible and mid-pressure fuel hose for performance or replacement work. The single biggest reason to buy is its construction: a CPE rubber inner with a layer of 304 stainless wire and a nylon outer braid that delivers a clean black-on-black look while handling common automotive fluids safely. For anyone fitting a fuel pressure regulator, routing lines in tight engine bays, or replacing aging hoses, this kit balances strength and flexibility.

Key Features

• Size: The 10ft length with a 0.31in ID and 0.56in OD provides ample run for most small engine and accessory routing tasks without excess joins.
• Working pressure: Rated to 750 psi and 2250 psi burst pressure, the hose is suitable for many fuel and fluid systems used in road and race applications.
• Temperature range: Operates from -22F to 248F, allowing use in cold starts and high underhood temperatures without rapid degradation.
• Durable construction: The CPE rubber inner plus 304 steel wire and nylon braid resist abrasion and maintain shape under pressure, improving longevity.
• Fluid compatibility: Compatible with fuel, race gas, diesel, oil, transmission fluid and hydraulic fluid, making it a versatile choice for swaps and custom plumbing.
• Bendability: A minimum bending radius of 63.5mm helps when routing around tight corners without kinking.

Who It's For

This hose kit is best for car enthusiasts, track day drivers, and home mechanics who need a reliable 6AN line for fuel systems, pressure regulator feeds, or oil and transmission plumbing. The black nylon braid also appeals to those who want a tidy, aftermarket appearance in engine bays.

It may not be ideal for ultra-high pressure or exotic chemical environments beyond the stated compatibility, and buyers who require factory-original OEM fittings or preassembled lines should look elsewhere. Installers unsure about AN fitting installation should plan for some learning or professional help.
