When upgrading or modifying your vehicle’s fuel system, a high-quality fuel line is essential to ensure consistent fuel delivery, durability, and leak-free performance. Evil Energy fuel line have gained a reputation in the automotive industry for providing affordable, high-quality fuel lines that work well in high-performance, racing, and daily driver applications.

In this article, we’ll dive into what makes Evil Energy fuel lines a great choice, their key features, how to choose the right one for your setup, and installation tips.

What is an Evil Energy Fuel Line?

An Evil Energy fuel line is a high-performance aftermarket hose designed to transport fuel efficiently while withstanding high pressures, extreme temperatures, and harsh conditions. Available in different materials, these fuel lines work with:

• Gasoline, diesel, and ethanol (E85) fuels
• Carbureted and fuel-injected systems
• High-performance engines, turbocharged, and supercharged setups
• Oil and transmission fluid applications

Evil Energy fuel lines are also AN-compatible, making them an excellent choice for AN (Army-Navy) fuel fittings and high-performance fuel systems.

Key Features of Evil Energy Fuel Lines

✅ Durability & High-Pressure Resistance

Evil Energy fuel lines are designed to withstand high fuel pressures, making them ideal for fuel-injected and high-performance applications. They are tested to handle up to 1000 PSI in some cases, ensuring reliable fuel flow without leaks or bursting.

✅ Available in PTFE, Nylon Braided, and Stainless Steel

Evil Energy offers different fuel line materials, each with unique benefits:

• PTFE (Polytetrafluoroethylene) Fuel Lines – Best for E85, methanol, and high-temperature applications. PTFE resists fuel permeation and prevents vapor leaks.
• Nylon Braided Fuel Lines – Lightweight and flexible, ideal for street cars and performance builds.
• Stainless Steel Braided Fuel Lines – Provides maximum durability and heat resistance, great for racing and off-road applications.

✅ Compatibility with Multiple Fuels

Evil Energy fuel lines can safely transport:
✔ Gasoline
✔ Diesel
✔ E85 (Ethanol-based fuel)
✔ Methanol
✔ Race fuels

This versatility makes them a great option for both stock and modified fuel systems.

✅ Leak-Proof & Corrosion-Resistant

• Designed for AN fittings (AN-6, AN-8, AN-10) for secure, leak-free connections.
• PTFE-lined fuel lines prevent fuel odor and vapor leaks, making them ideal for enclosed spaces.
• Resistant to corrosion, ensuring longevity even in extreme environments.

✅ Handles Extreme Temperatures

Evil Energy fuel lines can withstand:
High temperatures up to 450°F (depending on material)
❄ Cold temperatures as low as -76°F
This makes them suitable for daily driving, racing, and off-road performance applications.

How to Choose the Right Evil Energy Fuel Line

When selecting an Evil Energy fuel line, consider the following factors:

1. Fuel Line Size (AN Fitting Size)

Evil Energy fuel lines are available in multiple sizes, with the most common being:

• AN-6 (3/8") – Best for fuel-injected and street-performance setups.
• AN-8 (1/2") – Suitable for turbocharged or high-horsepower applications.
• AN-10 (5/8") – Used in high-flow fuel delivery systems.

Tip: Always match the AN size of your fuel line to your fuel pump, injectors, and fuel pressure regulator.

2. Material Type

✔ For daily drivers and mild performance builds: Nylon braided fuel lines are lightweight and flexible.
✔ For race cars and high-performance applications: Stainless steel braided PTFE fuel lines offer maximum durability and resistance to heat and pressure.
✔ For ethanol-based fuels (E85/Methanol): PTFE fuel lines prevent fuel degradation and vapor leaks.

3. Compatibility with AN Fittings

Evil Energy fuel lines are designed for AN fittings, which provide secure, high-pressure fuel connections. Be sure to use AN-compatible fittings for a leak-proof installation.

4. Intended Use & Pressure Rating

• Stock or mild performance cars: A standard AN-6 nylon braided fuel line works well.
• High-performance, turbo, or supercharged engines: An AN-8 or AN-10 stainless steel braided PTFE fuel line is ideal.
• Track and drag racing applications: High-pressure stainless steel fuel lines provide the best performance and reliability.

How to Install an Evil Energy Fuel Line

Tools & Materials Needed:

✔ Evil Energy fuel line (PTFE, nylon, or stainless steel braided)
✔ Matching AN fittings
✔ AN wrench set (to prevent damage to fittings)
✔ Hose cutter or angle grinder (for clean cuts)
✔ Fuel line clamps for securing connections

Step-by-Step Installation:

1️⃣ Plan Your Fuel Line Routing

• Ensure the fuel line is placed away from heat sources (exhaust manifolds, turbochargers, or radiators).
• Choose a secure mounting location to avoid movement or vibrations.

2️⃣ Cut the Fuel Line

• Use a hose cutter or angle grinder to get a clean, straight cut.
• For stainless steel braided lines, wrap the cutting area with electrical tape to prevent fraying.

3️⃣ Install AN Fittings

• Slide the AN fitting collar over the fuel line.
• Insert the fitting socket and tighten securely using an AN wrench.

4️⃣ Secure the Fuel Line

• Use clamps or brackets to prevent rubbing and movement.
• Avoid sharp bends or kinks in the line.

5️⃣ Check for Leaks & Test

• Start the fuel pump and inspect all connections for leaks.
• If necessary, tighten any loose fittings.

Is an Evil Energy Fuel Line Worth It?

Yes! Evil Energy fuel lines offer an affordable, high-quality solution for performance fuel systems. Whether you’re a weekend racer, daily driver, or tuning a high-horsepower build, Evil Energy fuel lines provide reliable fuel flow, high-pressure resistance, and leak-proof durability.

Key Takeaways:

✔ Affordable compared to high-end brands
✔ Available in PTFE, nylon, and stainless steel options
✔ Compatible with E85, gasoline, and methanol fuels
✔ Easy installation with AN fittings
✔ Resistant to heat, pressure, and fuel degradation

If you're looking to upgrade your fuel system reliability and performance, an Evil Energy fuel line is a cost-effective and high-performance choice.
