EVIL ENERGY AN10 PTFE Fuel Line Hose 20 ft Black — E85-Compatible Nylon-Braided, 1/2" ID High-Temp

EVIL ENERGY's AN10 PTFE fuel line kit is a 20-foot, E85-compatible, nylon-braided PTFE hose assembly built for high-temperature, high-pressure automotive fuel systems.

This AN10 (0.52" ID) PTFE fuel hose from EVIL ENERGY combines a smooth PTFE inner core with a protective nylon braid and black outer finish to deliver chemical resistance, wide temperature tolerance, and pressure capacity for performance vehicles. The kit supplies 20 feet (approximately 6 meters) of hose rated for fuels, lubricants, and coolants and is engineered to meet demanding conditions where durability and fuel compatibility matter.

How does this PTFE hose handle modern fuels like E85?

The PTFE inner liner resists chemical attack from ethanol blends, solvents, and additives, keeping fuel clean and preventing swelling or degradation common with some rubber hoses. Its construction reduces permeation and maintains consistent flow characteristics when used with gasoline, E85, diesel, and many lubricants.

• Compatibility: E85, gasoline, diesel, and most automotive lubricants.
• Material advantage: inert PTFE inner core resists chemical breakdown.
• Performance: minimizes fuel vapor permeation and maintains integrity over time.

What temperature and pressure conditions can this hose withstand?

This hose is rated to operate across a broad thermal window from -76°F to 446°F (-60°C to 230°C), making it suitable for under-hood heat and colder climates. It supports a maximum continuous working pressure of 1,250 PSI and a burst pressure up to 3,750 PSI, offering safety margins for fuel delivery systems and many high-pressure applications.

• Working temperature range: -76°F to 446°F (-60°C to 230°C).
• Working pressure: up to 1,250 PSI for steady operation.
• Burst pressure: up to 3,750 PSI for transient events.

What are the hose dimensions and installation considerations?

The hose measures 20 feet in length with an inner diameter of 1/2" (0.52") and an outer diameter of 0.69", corresponding to AN10 sizing commonly used in aftermarket fuel systems. Note that PTFE hoses are relatively stiff compared to rubber lines and should not be folded sharply; routing and fitting selection are important for a reliable, leak-free installation.

• Size: AN10 / 1/2" ID (0.52"), 0.69" OD, 20 ft (6 m) length.
• Handle with care: do not fold or crease the hose—use smooth bends.
• Recommendation: professional installation or experienced DIY routing to avoid stress points.

How will this hose improve my vehicle's fuel system performance?

Using a PTFE-lined hose reduces fuel contamination, resists swelling from ethanol fuels, and holds its shape under pressure—helping maintain consistent fuel delivery and system reliability. The nylon braid adds abrasion resistance and an extra layer of mechanical protection for tougher environments.

• Cleaner flow: smooth PTFE bore minimizes deposits and drag.
• Durability: nylon braid protects against chafing and external damage.
• Consistency: resists dimensional changes from heat or ethanol exposure.

Who is this for: EVIL ENERGY's AN10 PTFE fuel line kit is intended for performance vehicle owners, tuners, and professional mechanics who require ethanol-compatible, high-pressure fuel lines for aftermarket pumps, rails, fuel filters, and EFI systems. It’s ideal when chemical resistance, temperature tolerance, and pressure capacity are priorities; however, because PTFE hose is relatively stiff, installers should have experience or seek professional fitting to ensure safe routing and leak-free connections.
