EVIL ENERGY 12AN PTFE Fuel Line Kit 10ft - High Temp Pressure Ready

In this review the EVIL ENERGY 12AN PTFE Fuel Line Kit is evaluated for users who need a high temperature, high pressure feed line for performance vehicles and motorsport applications. The single biggest reason to consider this kit is its combination of a PTFE core with a nylon braid that delivers a wide working temperature range and high burst strength, making it well suited where chemical compatibility and pressure resistance matter. The review notes installation stiffness and the need for professional fitting as practical considerations.

Key Features

• 12AN size: The 5/8' ID and 0.79' OD provide a generous flow capacity for upgraded fuel systems and high-volume pumps.
• 10 ft length: A full 10 foot spool covers long runs or multiple feed and return lines without splicing in many installations.
• Wide temperature range: Rated from -40F to 250F, the hose tolerates extreme underbonnet heat and cold in daily and track use.
• High pressure rating: With a 1000 psi working pressure and 3000 psi burst pressure, the line is designed for demanding fuel system pressures.
• PTFE core with nylon braid: The PTFE inner offers chemical resistance for fuels, lubricants and coolants while the braid adds abrasion protection.
• Complete kit as shown: The product includes the components pictured so buyers receive fittings and hose together for assembly.

Who It's For

This kit is aimed at enthusiasts, fabricators, and racers who need a robust, chemically compatible fuel line for E85 and other automotive fuels and lubricants. It is particularly useful when runs require high temperature resistance or where braided protection is desired.

It is not ideal for do-it-yourselfers who expect very flexible hose; the PTFE core is relatively stiff and cannot be sharply bent or folded, so buyers should consider professional installation or ensure routing allows gradual curves.

Pros & Cons

Pros

• High temperature and pressure capability for demanding engine bays.
• Durable PTFE inner provides broad chemical compatibility with fuels and coolants.
• 10 ft length and included parts make it convenient for full installations.
• Good value relative to specialty high-pressure PTFE lines, according to customers.

Cons

• PTFE hose is relatively hard and not suitable for tight bends, requiring careful routing or professional installation.
• Some customers reported mixed experiences with fittings and occasional leakage, so careful assembly and torqueing is important.

Specifications

Our Verdict

The EVIL ENERGY 12AN PTFE Fuel Line Kit is a practical choice for performance builds that require chemical compatibility and high pressure tolerance. It offers good value with a 10 ft length and solid temperature and pressure ratings, but buyers should plan installations to avoid tight bends and take care during assembly to prevent leaks. Recommended for fabricators and racers who can accommodate a stiffer PTFE hose.

Frequently Asked Questions
