8AN 16FT PTFE Fuel Line Hose Kit - High-Pressure E85 Ready

In this review of the 8AN 16FT PTFE Fuel Line Hose Kit, the bottom line is clear: this kit is for anyone who needs a durable, high-pressure fuel hose that is compatible with E85 and a range of automotive fluids. The reviewer found the combination of a smooth PTFE inner liner and a nylon braided outer cover useful for clean flow and abrasion resistance, and the included assortment of 8AN hose ends and tools makes it a practical pick for retrofit work or custom fuel lines. Installation is best done by a professional if you have not worked with AN fittings before.

Key Features

• 16 ft PTFE hose: Provides ample length for most custom fuel routing tasks without splicing, reducing leak points and simplifying installation.
• High pressure rating: With a maximum working pressure of 2500 psi and a bursting pressure near 8000 psi, it suits high-demand fuel and fluid systems.
• E85 compatibility: The PTFE inner layer is chemically resistant and works with pump gas, diesel, E85, transmission fluid, oil, and coolant.
• Complete fittings set: The kit includes 8AN hose ends in straight, 45, 90 and 180 degree angles so users can make secure connections in tight or awkward spaces.
• Temperature range: Rated from -76F to 446F, it handles extreme underhood temperatures and cold starts without losing integrity.
• Installation tools included: Gloves and a wrench are provided to help with assembly and protect hands while tightening fittings.

Who It's For

This kit is aimed at automotive enthusiasts, fabricators, and professional mechanics who need a reliable, chemical-resistant fuel line for E85-capable systems or other high-pressure fluid applications. The 16 ft length and varied fittings make it a good choice for custom fuel routing, catch can lines, or fuel return systems on modified engines.

It is not ideal for a novice who expects a plug-and-play factory replacement without any fitting knowledge; if you have not installed AN fittings before, the product notes recommend professional installation. Also, those needing a stainless steel braided exterior rather than nylon should look at other options.

Pros & Cons

Pros

• Durable PTFE inner liner with a protective nylon braid provides chemical resistance and abrasion protection.
• High working and bursting pressures suit demanding fuel and fluid systems, including E85 setups.
• Comes with a comprehensive set of 8AN hose ends and basic tools for assembly, reducing the need to source fittings separately.
• Wide temperature tolerance ensures reliability across varied climates and engine bay conditions.

Cons

• Installation can be challenging for first-time users and professional fitting is recommended.
• The outer braid is nylon rather than stainless steel, which some users may prefer for extra abrasion resistance.
