EVIL ENERGY 6AN 3/8-inch PTFE LS Swap EFI Fuel Line Fitting Kit | E85 Nylon Braided Fuel Hose With Fittings 10-26FT

Upgrade your fuel system with the EVIL ENERGY PTFE Fuel Hose—a 6AN 3/8 LS Swap EFI Fuel Line Fitting Kit engineered for clean installs, high pressure, and long-term reliability. Built around an E85 nylon braided fuel hose with PTFE core, this kit is ideal for LS swaps, EFI conversions, and high-demand gasoline lines on street or track.

Why it works: PTFE = chemical + heat resistance; nylon-braided, stainless-reinforced jacket = abrasion protection; precision PTFE fittings + adapters = leak-free sealing.

Key Features

• PTFE Fuel Hose, built for EFI: 6AN PTFE braided fuel line maintains stable flow under EFI pressures—perfect as a 3/8 high pressure fuel line.
• E85 & ethanol-safe: True E85 nylon braided fuel hose resists ethanol, methanol, gasoline, and modern fuel blends.
• Complete 6AN fuel line kit: Includes reusable PTFE Fittings (straight/90°/6AN 45° PTFE fitting) for tight-radius routing.
• NPT & quick-connect ready: Versatile NPT fitting adapters and 6AN to 3/8 quick-connects integrate pumps, filters, regulators, and GM LS fuel rails.
• Clean 'gasoline lines' upgrade: A durable 3/8 braided fuel line kit for return/returnless EFI systems and carb return lines.
• Braided fuel line kit durability: Nylon over steel braided reinforcement resists heat, abrasion, and vibration for long service life.

About this item

• Wide Application: The EVIL ENERGY PTFE nylon braided fuel line kit is ideal for EFI LS systems, LS engine swaps, and EFI conversions. It can also be used as a fuel injection hose, turbo oil feed line, boost line, transmission oil cooler line, carburetor fuel line, fuel return line, vapor return line, vacuum line, fuel supply line, and turbocharger fuel line—perfect for high-temperature, high-pressure automotive applications.
• High Performance: The AN-6 nylon braided high-pressure PTFE fuel line withstands extreme heat, high pressure, and harsh conditions without degradation, ensuring consistent flow and reliable performance.
• Universal Compatibility: The PTFE fuel hose is resistant to gasoline, E85, ethanol, methanol, diesel, lubricants, and coolant—making it suitable for virtually all automotive fuel systems.
• Durable Construction: Compared with rubber hoses, the braided PTFE fuel line offers superior resistance to abrasion, heat, and corrosive fuels—providing longer service life in demanding builds.
• Installation Notice: PTFE hose is relatively rigid and should not be bent or folded in half. Professional installation is highly recommended to ensure a leak-free and long-lasting setup.

Compatibility & Use Cases

• LS Swap EFI fuel line kit (return/returnless rails), EFI conversions, boosted builds
• Pumps, filters, fuel pressure regulators (via NPT fittings), hard-to-reach bays (use 6AN 45° PTFE fitting for compact turns)
• Works as 3/8 fuel line / 3/8 PTFE fuel line / 3/8 steel braided fuel line replacement in performance applications

Installation Tips

• Cut PTFE hose with a dedicated cutter; pre-fit the olive/ferrule; avoid twisting the liner.
• Check flow direction on filters/regulators; pressure test before driving.
• PTFE is stiffer than rubber—professional installation recommended for best results.
