Why Upgrade to a PTFE Fuel Line Kit?

Traditional rubber fuel hose breaks down over time when exposed to ethanol-blended fuels and modern additives. PTFE-lined hose provides superior resistance to chemical degradation, fuel permeation, pressure fatigue, and heat exposure.

Translation: fewer fuel smells, fewer leaks, and dramatically less regret later.

Perfect for LS Swaps

LS swaps commonly require custom fuel plumbing due to chassis differences, aftermarket fuel rails, return-style systems, and upgraded fuel pumps. This AN6 PTFE kit simplifies installation while supporting the flow demands of modern EFI engines.

Especially useful when your “budget LS swap” somehow became a full custom build.

Built for Modern Performance Fuels

PTFE hose systems resist fuel permeation and chemical breakdown far better than traditional rubber-lined hoses. This makes them ideal for gasoline, E85, methanol, race fuel, and aggressive ethanol-blended applications.

Because modern ethanol fuels absolutely destroy cheap fuel hose over time.

Appropriate for Wide Usage: The PTFE nylon braided fuel line is perfect to be used in more than a few prime-temperature and prime-pressure applications.
Notice: The PTFE LS fuel hose is rather hard and cannot be bent or folded in half. Professional installation is extremely advisable.

Nylon Braided Exterior

The nylon braided outer layer provides excellent abrasion resistance while remaining lighter and more flexible than traditional stainless braided hose. This simplifies installation while maintaining a clean motorsports appearance.

Translation: fewer shredded hands and slightly less emotional damage during assembly.

Designed for High-Flow EFI Systems

The AN6 sizing supports modern EFI fuel delivery requirements for upgraded pumps, larger injectors, turbocharged applications, and aggressive tuning combinations while maintaining excellent flow characteristics.

Basically designed for cars where fuel consumption resembles industrial equipment operation.

Why Choose EVIL ENERGY?

EVIL ENERGY continues to provide enthusiasts with affordable PTFE plumbing hardware, AN fittings, and performance fuel system solutions. Their PTFE fuel line kits deliver reliable sealing, strong chemical resistance, and installation flexibility for both street-driven and motorsports applications.

Because rebuilding a leaking fuel system after final assembly is not the kind of character development anyone requested.
