EVIL ENERGY PTFE-Lined AN4 Fuel Hose Kit, 10 ft Black — E85 Compatible, High-Temp Strength

EVIL ENERGY 4AN PTFE Fuel Line Kit is a 10-foot, AN4 (ID 3/16") PTFE-lined, nylon-braided fuel hose engineered for high-temperature, high-pressure automotive fuel systems including E85 mixtures.

This kit provides a durable fuel delivery solution when you need chemical resistance, wide temperature tolerance, and the strength of nylon braid. The PTFE inner liner resists most fuels, lubricants, and coolants while the braided outer cover protects the hose from abrasion and helps maintain shape under pressure. It's intended for installations that require a compact 4AN (AN4) diameter with reliable performance across extreme environments.

What are the core specifications and performance limits?

The EVIL ENERGY 4AN hose has an inner diameter of 3/16" (0.19 in) and an overall outside diameter of 0.36". The kit contains a continuous 10-foot length suitable for routing fuel lines in many vehicle layouts. Temperature and pressure ratings let you match the hose to demanding engine bay conditions.

• Inner diameter: 3/16" (0.19 in); outside diameter: 0.36"
• Length: 10 feet continuous hose
• Operating temperature range: -76°F to 446°F (-60°C to 230°C)
• Working pressure: up to 1,500 PSI; burst pressure: approximately 4,500 PSI

Is this hose compatible with E85 and other common automotive fluids?

Yes — the PTFE liner provides broad chemical resistance, making it suitable for ethanol-blended fuels like E85 and many other automotive fluids. The hose is designed to handle fuels, lubricants, and coolants without rapid degradation, which helps maintain safe fuel delivery in modified or stock systems alike.

• Compatible with E85 and gasoline blends
• Resists common engine oils and coolant additives
• PTFE liner minimizes fuel permeation and swelling

How should I install and route this PTFE braided hose?

Because the PTFE-lined hose is relatively stiff compared with rubber fuel lines, it can't be folded sharply. Plan a smooth routing path and use appropriate fittings and clamps for AN4 sizes. Professional installation is recommended to ensure leak-free connections and to avoid kinking the hose.

• Avoid tight bends; use gentle curves or fittings to change direction
• Use AN4-compatible fittings, clamps, or adapters for secure connections
• Inspect fittings for proper seating and perform pressure checks after install

Will this hose work in high-heat engine bays and performance applications?

The hose is engineered for a wide temperature envelope, so it tolerates elevated engine bay heat and cold starts alike. Combined pressure ratings and the protective nylon braid make it suitable for turbocharged, supercharged, or other higher-stress fuel delivery systems where durability matters.

• Temperature tolerance down to -76°F and up to 446°F
• Nylon braid adds abrasion resistance and structure under pressure
• High working pressure (1,500 PSI) supports demanding fuel systems

Who is this kit for? EVIL ENERGY's 4AN PTFE Fuel Line Kit is aimed at performance enthusiasts, tuners, and professional mechanics who need a compact AN4-sized hose that resists ethanol blends and withstands high temperatures and pressures. If you plan tight engine-bay routing that requires flexibility, consider whether this stiffer PTFE-lined option suits your layout; otherwise, it's an excellent choice for robust, chemically resistant fuel lines in modified and high-performance vehicles.
