EVIL ENERGY 8AN PTFE Fuel Line Kit, AN8 E85 Nylon Braided Hose 10FT

In this review of the EVIL ENERGY 8AN PTFE Fuel Line Kit, the bottom line is simple: this hose set is aimed at enthusiasts and professionals who need a high temperature, high pressure replacement or upgrade for fuel delivery. The review finds the kit valuable for applications that require chemical resistance and strength, because the PTFE core with nylon braid tolerates extreme temperatures and pressures while covering common automotive fuels and lubricants. Measure fittings carefully before buying, since the hose is relatively rigid and requires professional handling for best results.

Key Features

• Size and fit: The hose has an ID of 0.39in and an OD of 0.55in, providing a compact inner diameter for tight fuel systems where AN8 fittings are used.
• Length: At 10ft the kit supplies enough hose for many single-system runs or for cutting to length for custom installations.
• Temperature range: The PTFE construction works from -76F to 446F so it can handle engine bay heat and cold starts without degrading.
• Pressure capability: With a max working pressure of 1500psi and bursting pressure of 4500psi, the hose is built for high pressure fuel and boost-fed systems.
• Media compatibility: The PTFE core is compatible with almost all automotive fuels, lubricants, and coolants, making it versatile for performance swaps.
• Durability note: The PTFE nylon braided hose resists heat and abrasion, though it is relatively hard and must not be folded sharply.

Who It's For

The EVIL ENERGY 8AN PTFE Fuel Line Kit is best for automotive hobbyists, tuners, and professional mechanics who need a reliable, high temperature hose for E85, gasoline, or other fuel systems. It suits projects where chemical compatibility and pressure capacity matter, including turbocharged or EFI setups that run elevated pressures.

It is not ideal for casual DIYers who expect a highly flexible hose to route easily in very tight spaces, since PTFE tubing is relatively stiff and requires careful measuring and professional installation to avoid kinking or improper fittings.

Pros & Cons

Pros

• High temperature tolerance makes it suitable for demanding engine bay environments.
• Strong pressure ratings and high burst pressure provide a safety margin for performance applications.
• Compatible with E85 and a wide range of fuels and lubricants, increasing versatility.
• Comes in a full 10ft length so users can cut to fit for custom runs.

Cons

• PTFE hose is relatively hard and not easily folded, so routing can be challenging and professional assembly is advised.
• Some users report mixed experiences with fittings and potential leakage if fittings are not installed correctly.
