6AN Fuel Line Kit Nylon Braided Hose 20FT - Durable, High Pressure

In this review the EVIL ENERGY 6AN fuel line kit is evaluated for DIY mechanics and performance shops that need a flexible, corrosion-resistant fuel or coolant hose solution. The single biggest reason to consider it is the combination of a CPE rubber inner hose with 304 steel wire and nylon outer braid that delivers a wide compatibility range and strong pressure ratings, making it useful as a fuel supply, return, cooler or oil feed line. The review looks at build, fittings, and real-world installation notes so buyers know what to expect.

Key Features

• Multi-purpose use: The kit works as a transmission oil cooler line, fuel return or supply line, coolant hose, vacuum line or turbo cooler line for flexible installation options.
• Material construction: A CPE rubber inner tube with 304 steel wire and nylon braid offers abrasion resistance and chemical compatibility with diesel, oil and race gas.
• Pressure and temperature range: Rated to 500psi working pressure and a 2000psi burst pressure with a -22F to 248F temperature range for demanding engine bay conditions.
• Complete fittings set: Includes 10 swivel hose ends in straight and angled orientations plus two 6AN to 6AN fittings and clamps to cover common routing needs.
• Length and sizing: The 20ft length with a 0.34in hose ID and 0.54in OD gives ample reach for multiple runs and custom setups.

Who It's For

This kit is best for automotive enthusiasts, fabricators and small shops who need a versatile run of 6AN hose for fuel, oil feed, transmission cooler or vacuum lines and prefer a braided appearance and stainless reinforcement. It is suited to projects requiring a durable, chemically compatible hose that holds up under elevated pressures and temperatures.

Those who should look elsewhere include owners who need pre-assembled, vehicle-specific lines or plug-and-play OEM replacements; this kit requires cutting, fitting and some plumbing skill, and a few buyers report variable ease of installation when working with swivel fittings.

Pros & Cons

Pros

• Good material build offers strong abrasion and chemical resistance for engine bay fluids.
• Comprehensive fitting assortment covers multiple routing angles for custom installations.
• High working and burst pressures provide confidence for high-demand applications.
• Long 20ft length and compact 0.34in ID make it adaptable to many runs.

Cons

• Installation experiences are mixed; some users find the fittings tricky to assemble and occasional leakage has been reported.
• Requires cutting and assembly tools, so not ideal for users wanting ready-made lines.
