Medoon 6AN PTFE Fuel Line Kit — 3/8" ID 26ft Stainless-Steel Braided Hose with AN6 Fittings, E85/EFI Ready

Medoon 6AN PTFE fuel line kit is a 26-foot, 3/8" internal-diameter stainless-steel-braided PTFE hose system with matching AN fittings and accessories designed for EFI, LS swaps, and E85-compatible fuel delivery.

This complete plumbing set bundles long-length PTFE-lined hose with AN6 aluminum fittings and installation hardware so you can route a durable fuel, oil, or vapor line for high-performance and retrofit builds. Engineered for wide temperature extremes and high pressures, the hose is suitable for fuel-injection applications, turbo oil feeds, and transmission cooler lines. The kit focuses on corrosion resistance and fuel compatibility while giving you the length and connectors needed for many swap and custom installations.

How does this kit support EFI and LS swap fuel systems?

The PTFE inner liner resists chemical attack from gasoline, E85 and most lubricants, while the stainless-steel braided outer layer maintains mechanical strength and abrasion protection. Matched AN6 fittings and included couplers let you create secure, leak-minimized connections commonly required in EFI conversions and LS engine swaps.

• 3/8" (0.375") inner diameter suited to typical EFI flow rates.
• 26 feet of hose to reach tanks, rails, and external pumps in swap layouts.
• 3000 psi working pressure and 10000 psi burst rating for robust performance.
• T6061 aluminum AN fittings for lightweight, corrosion-resistant joints.

What components are included and why they matter?

This kit supplies fittings and tools to finish multiple connections without hunting down parts. Along with the hose, you receive hose ends, quick-disconnect fittings, clamps, couplers, and a reaming/installation wrench—items intended to save time and help build safe, tidy lines.

• 12 PTFE hose-end fittings sized for AN6 terminations.
• 4 quick-disconnect fittings for serviceable connections.
• 6 hose-separator clamps to anchor and route lines cleanly.
• 2 AN6 male couplers, a standard wrench, and a reaming tool for proper assembly.

What are the performance and temperature limits?

The hose is rated to operate in extreme environments and handle high-pressure demands typical of performance fuel systems. Temperature tolerance and pressure ratings provide a wide operational window but follow installation guidance to avoid kinking or sharp bends that can compromise flow or fittings.

• Working temperature: -76°F to 446°F (-60°C to 230°C).
• Working pressure: up to 3000 psi; burst pressure up to 10000 psi.
• Outer diameter: approximately 0.465" for routing and clamp sizing.
• Materials: PTFE liner with nylon-wrapped stainless-steel braid and T6061 aluminum fittings.

How should I install and maintain the hose kit?

The PTFE-lined hose is relatively stiff compared with rubber lines and should not be sharply bent or folded. Professional or experienced DIY installation is recommended to ensure correct cutting, reaming, and fitting torque so connections remain leak-free and durable under vibration.

• Do not fold or sharply kink the hose—route with gentle bends and adequate support.
• Use the included way reaming tool for clean internal edges before fitting.
• Secure lines with provided clamps and inspect fittings for tightness after initial runs.
• Replace damaged sections rather than attempting repairs on compromised hose.

Who is this for: The Medoon 6AN PTFE Fuel Line Kit is aimed at mechanics, performance enthusiasts, and garage fabricators completing EFI systems, LS engine swaps, turbo oil feeds, or custom transmission cooler and return line projects. It suits anyone needing a long, chemically compatible, high-pressure fuel hose with a broad complement of AN6 fittings and installation hardware—just plan the routing, follow installation best practices, and consider professional assembly if you’re unfamiliar with PTFE-lined hose procedures.
