EVIL ENERGY 6AN PTFE Fuel Line Kit 16ft - High Temp, High Pressure

In this review of the EVIL ENERGY 6AN PTFE Fuel Line Kit, the bottom line is simple: this kit is for builders and tuners who need a durable, high temperature and high pressure fuel line that handles modern fuels. The kit's 16 ft length and PTFE core with nylon braid make it well suited to custom installs and E85-capable systems, and the single biggest reason to buy is its temperature and pressure resistance which reduces fuel-line downtime in demanding applications. Measure fittings carefully before purchase and plan for professional installation for best results.

Key Features

• Size and length: The 5/16 in ID and 16 ft length provide ample run for most custom fuel routing and allow flexibility when planning hose runs.
• Temperature range: Rated from -76F to 446F, the hose handles extreme underhood heat and cold without losing integrity.
• Pressure capacity: With a max working pressure of 1500 psi and bursting pressure of 4500 psi, the line tolerates high-pressure fuel systems used in performance builds.
• E85 compatibility: The PTFE core is compatible with E85, gasoline, lubricants, and coolants, making it suitable for modern ethanol blends.
• Durability: The nylon braid adds abrasion resistance for routed runs through engine bays, helping the hose resist wear in tight installations.

Who It's For

This kit is aimed at experienced DIYers, tuners, and professional installers building or upgrading fuel systems that demand heat and pressure resilience, such as turbocharged or E85-converted engines. The length and AN6 sizing make it a practical choice for custom plumbing where a long continuous run of PTFE-lined hose is desired.

Those who should look elsewhere include beginners who expect an easily bendable hose for tight, folding runs and anyone unwilling to deal with fiddly fittings; the hose is relatively stiff and professional or careful installation is recommended to avoid routing problems or fitting issues.

Pros & Cons

Pros

• High temperature rating provides reliability in hot engine bays.
• Strong pressure ratings suit performance and high-pressure fuel setups.
• Broad chemical compatibility, including E85, makes it versatile for modern fuels.
• Generous 16 ft length reduces the need for multiple joins in custom installations.

Cons

• The PTFE nylon braided hose is relatively stiff and cannot be folded in half, which can complicate tight bends.
• Some users report the fittings can be fiddly and may require care or professional attention to avoid leaks.
