EVIL ENERGY 3/8 in OD Aluminum Fuel Line Kit 25ft - Durable Hard Line

In this review the EVIL ENERGY 3/8 in OD Aluminum Fuel Line Kit is evaluated for DIY mechanics and automotive shops that need a reliable, lightweight hard line for fuel and fluid routing. The bottom line: this 25ft coil of 1060 grade aluminum tubing stands out for its balance of flexibility and strength, making it a practical option for fuel return lines, transmission lines, and other low- to mid-pressure applications where corrosion resistance and thermal conductivity matter.

Key Features

• Size and capacity: The 3/8 in OD tube with 0.32 in ID and 0.05 in wall thickness provides a consistent internal flow and works up to 700 PSI, suitable for many automotive fluid duties.
• Material quality: Constructed from 1060 grade aluminum that meets ASTM B210 specifications, the seamless tubing is corrosion resistant and thermally conductive for longer service life in underhood environments.
• Temperature range: Rated from -58F to 392F, the tube handles hot engine bays and cold starts without brittle behavior or softening within that window.
• Complete kit: The 25ft coil ships with a tube cutter, bender, deburring tool, four tube clamps, and six 6AN female to 3/8 in compression fittings to allow independent installation and fitting fabrication.
• Versatile application: Usable with diesel, gasoline, E85, transmission oil, water and air, the tubing adapts to practices like fuel returns, AC lines, and air compressor plumbing.

Who It's For

The kit is aimed at gearheads, restoration builders, and small shops that want a lightweight, corrosion-resistant metal hard line they can bend and cut on the bench or in the garage. It suits those replacing rubber hoses with a firmer line or fabricating custom runs for fuel returns, transmission cooling or accessory air lines.

It is less appropriate for high-pressure injection fuel rails or applications requiring crimp-style fittings not supported by compression fittings included here. If a builder needs pre-formed rigid lines or lines certified for extremely high pressures beyond the listed burst rating, they should look elsewhere.

Pros & Cons

Pros

• Lightweight aluminum construction resists corrosion and reduces weight compared with steel hard line.
• Comes with tools and six compression fittings so a user can cut, bend and deburr without sourcing extras.
• Wide temperature tolerance and compatibility with common automotive fluids adds installation flexibility.

Cons

• The 700 PSI working pressure is adequate for many uses but is not intended for high-pressure direct injection fuel systems.

Our Verdict

For DIY installers and small shops needing a flexible, corrosion-resistant hard line, this 25ft EVIL ENERGY aluminum tube kit delivers good value thanks to its material grade, included tools and fittings, and broad fluid compatibility. It is a practical choice for fuel return, transmission, AC and air lines, provided the user does not require extremely high pressure ratings or preformed tubing.

Frequently Asked Questions

Can this tube be used with gasoline and E85?
Yes, the 1060 aluminum tube is compatible with gasoline and E85 as listed for common automotive fluid use.

Are fittings and tools included to install the line?
Yes, the kit includes a tube cutter, bender, deburring tool, four tube clamps and six 6AN female to 3/8 in compression fittings for on-vehicle bending and fitting.

Is this suitable for high-pressure fuel injection systems?
No, the working pressure of 700 PSI and the included compression fittings make it unsuitable for modern high-pressure direct injection rails that require far higher ratings and specific fittings.
