Medoon PTFE Fuel Line Kit 3/8" 26FT — Stainless-Steel Braided Hose for EFI & LS Swaps

Medoon 6AN PTFE Fuel Line Kit is a complete 26-foot stainless-steel braided PTFE hose system with fittings for EFI, LS swaps, E85, turbo oil feed and other high-performance fuel or fluid lines.

This kit combines a long run of 3/8" (inner) PTFE-lined hose with corrosion-resistant stainless-steel braid and a full complement of AN fittings to simplify fuel system installs. Built for high temperature and pressure environments, the set includes adapters, quick-disconnects, clamps and the basic tools needed to assemble and route custom lines for engine swaps, fuel-injection upgrades and auxiliary oil or coolant lines.

How does this kit handle different fuels like E85 and gasoline?

The PTFE inner liner resists chemical attack and works with a wide range of automotive fluids, including gasoline, ethanol blends such as E85, lubricants and coolants. The stainless-steel braid and nylon jacket protect the liner from abrasion and external damage while fittings use T6061 aluminum to resist corrosion in typical engine bay environments.

• Compatible with gasoline, E85, diesel blends, oil, and coolant.
• PTFE liner resists swelling and degradation from ethanol and fuels.
• Stainless-steel braid adds abrasion resistance and pressure containment.
• T6061 aluminum fittings balance strength with light weight.

What sizes, temperatures and pressures can I expect?

The hose has a 3/8" inner diameter and a 0.465" outside diameter, offering a practical size for many EFI and LS swap applications. It is rated for wide operating temperatures and high pressures so it can be used in demanding under-hood conditions when installed correctly.

• Inner diameter: 3/8"; outside diameter: 0.465".
• Working temperature range: -76°F to 446°F (-60°C to 230°C).
• Working pressure: up to 3,000 psi; burst pressure approximately 10,000 psi.
• Total hose length supplied: 26 feet for multiple runs or long-routing jobs.

What is included and what tools are provided for assembly?

The kit is packaged to be installation-ready for many custom projects. In addition to the 26 feet of braided PTFE hose, you receive multiple fittings and a couple of basic tools to make assembly and routing simpler for experienced installers.

• 12 PTFE AN6 hose end fittings and 4 quick-disconnect fittings for fast service points.
• 6 hose separator clamps to keep lines neat and secure during routing.
• 2 x 6AN male couplers, 1 standard wrench and 1 way reaming tool for prepping hose ends.
• Lightweight union adapter and all aluminum T6061 hardware for corrosion resistance.

Who this kit is for: Automotive fabricators, performance builders and DIY mechanics doing LS engine swaps, EFI upgrades, turbo oil feed installations or custom fuel-system work will find this Medoon kit useful. It provides a long, chemically compatible PTFE hose and a broad assortment of AN fittings and hardware so you can create multiple runs or serviceable connections. Note: the PTFE-lined hose is relatively stiff; professional or experienced installation is recommended to avoid kinks and ensure leak-free terminations.
