EVIL ENERGY 6AN PTFE Fuel Hose Line 20ft - High-Temp, High-Pressure

In this review the EVIL ENERGY 6AN PTFE fuel hose line is evaluated for installers and enthusiasts who need a long, durable PTFE hose for fuel systems and related lines. The single biggest reason to consider it is its combination of broad chemical compatibility and high temperature and pressure ratings, which make it suitable for E85, methanol and other demanding fluids. The 20ft length and included installation instructions aim to make routing easier, though buyers should measure fittings and plan bends before cutting.

Key Features

• Size and length: The 6AN hose provides 20ft of PTFE-lined hose with a 0.31in inner diameter for long runs without jointed sections.
• High temperature range: Rated from -76F to 446F, the hose tolerates extreme ambient and engine-compartment heat for wider application options.
• Pressure capability: With a 1500 psi working pressure and 4500 psi burst rating, it handles higher-pressure fuel systems and some boost or injection uses.
• Chemical compatibility: PTFE construction is compatible with E85, methanol, diesel, engine oil and many other fluids, reducing worry about degradation.
• Versatile uses: Suitable as a fuel injection hose, return line, vacuum or vapor line and for LS swaps where a long, reliable run is required.
• Included guidance: Installation instructions are provided to help with fitting and safe routing for professional or experienced DIY installers.

Who It's For

The EVIL ENERGY 6AN PTFE hose is best for automotive enthusiasts, engine-swappers and professional installers who need a long, chemically resistant hose that stands up to high heat and pressure. It is particularly useful for E85 and methanol applications where standard rubber hoses can fail.

Those who should look elsewhere include users who require a very flexible hose for tight coils or frequent bending, since the braided PTFE hose is relatively stiff and has a minimum bend radius of about 3.5in. Also double-check AN sizing if you rely on adapters or mixed fittings to avoid fit issues.

Pros & Cons

Pros

• Excellent chemical compatibility with fuels like E85 and methanol, reducing fuel-swelling concerns.
• High temperature and pressure ratings make it suitable for demanding engine-bay use.
• Long 20ft length reduces the need for multiple joins and simplifies routing for swaps.
• Customers report good value, dependable leak resistance and a clean appearance.

Cons

• Relatively stiff construction limits tight bending; maintain at least a 3.5in bend radius and consider fittings for tight runs.
• Some users reported fit disagreements when mixing with non-matching AN fittings, so verify connector sizes before purchase.
