8AN PTFE Fuel Line Kit 26ft - High-Pressure LS Swap Fuel Hose

In this review of the 8AN PTFE Fuel Line Kit the bottom line is clear: this kit is for builders who need a high-performance, fuel-compatible hose run for EFI, LS swaps, turbo oil feed or transmission cooler lines. The most compelling reason to buy is the complete 26ft of PTFE-lined, nylon stainless steel braided hose paired with a wide set of fittings and tools, which removes the hassle of sourcing parts separately. This review looks at durability, fitment, and the practical tradeoffs of a relatively stiff PTFE assembly.

Key Features

• Complete kit: Delivers 26ft of AN8 PTFE hose plus 12 hose end fittings, quick disconnects and separators so most EFI and LS swap jobs can be started immediately without extra parts.
• High pressure capability: The hose is rated to a maximum working pressure of 2500psi and a bursting pressure of 8000psi, which covers demanding fuel injection and turbo oil feed applications.
• Temperature range: Works from -76F to 446F so it tolerates both cold starts and high underhood temperatures for gasoline, ethanol blends and lubricants.
• Durable construction: PTFE synthetic rubber inner with nylon stainless steel braid and T6061 aluminum fittings provides corrosion resistance and chemical compatibility across fuels and coolant.
• Installation tools included: The kit ships with a standard wrench and way reaming tool to help seat fittings cleanly, reducing trips to the bench for additional tools.

Who It's For

This kit suits car builders swapping an LS engine, tuners running EFI or E85, and anyone needing a long run of AN8-rated hose for fuel, vapor return or turbo oil feed. The full set of fittings and clamps makes it useful for custom installations where source continuity matters.

It is not ideal for someone seeking a soft, highly flexible hose for tight bends or simple OEM replacement where a factory-style rubber hose is preferred. Because PTFE hose is relatively hard, professional installation or at least some experience with AN fittings is recommended.

Pros & Cons

Pros

• Comprehensive kit reduces extra shopping and ensures matched AN8 components for a clean system build.
• High working and bursting pressures provide confidence for high-flow EFI and turbo oil lines.
• Wide temperature tolerance and PTFE inner tube provide chemical compatibility with fuels and lubricants.
• Includes useful installation tools and hose separators to tidy routing and secure fittings.

Cons

• PTFE hose is relatively stiff and does not fold in half, which makes routing in very tight spaces more difficult.
• Proper assembly benefits from experience; novices may want professional help to avoid leaks.

Our Verdict

The 8AN PTFE Fuel Line Kit is a sensible purchase for DIY engine swaps and high-performance fuel system builds because it pairs a long run of chemically compatible, high-pressure hose with matching fittings and basic tools. It delivers strong value when buyers need durability and pressure capacity, but expect stiffer routing and plan for careful assembly or professional installation.

Frequently Asked Questions

Is this hose compatible with E85?
The PTFE inner lining is compatible with E85 and most automotive fuels and lubricants.

Can the hose be bent tightly around sharp corners?
The PTFE hose is relatively hard and does not fold in half; tight bends require planning or additional fittings to avoid kinks.

Are installation tools included?
Yes, the kit includes a standard wrench and way reaming tool along with separator clamps and couplers to aid assembly.
