EVIL ENERGY 6AN Fuel Line Kit 25ft Black — CPE Nylon-Braided Hose with 10 Swivel Fittings, 750 psi

EVIL ENERGY 6AN Fuel Line Kit is a complete 25-foot CPE nylon-braided hose system with ten 6AN swivel fittings designed for durable, high-pressure fluid routing in automotive and racing applications.

This kit delivers a ready-to-install solution for fuel, oil, coolant and other fluid lines where flexibility, abrasion resistance and reliable connections matter. The hose combines a CPE rubber core with a 304 stainless wire layer and a nylon outer braid for strength, while the anodized aluminum 6AN fittings provide swivel ends in multiple angles to simplify routing. Rated for a 750 psi working pressure and a wide temperature range, it covers many aftermarket plumbing needs from fuel supply to turbo cooling lines.

How robust is the hose for high-pressure or racing environments?

The hose is engineered to tolerate demanding conditions: a maximum working pressure of 750 psi and a burst pressure near 2250 psi offer a large safety margin for most automotive uses. The combination of a CPE inner tube, stainless steel reinforcement and nylon braid balances flexibility with resistance to kinking and abrasion. Temperature performance spans from -22°F up to 248°F, making it suitable for cold starts and hot engine bays.

• Working pressure: 750 psi for sustained use.
• Burst pressure: 2250 psi safety threshold.
• Temperature range: -22°F to 248°F for varied climates.
• Construction: CPE core, 304 stainless wire, nylon outer braid.

Which fluids and systems can this 6AN kit handle?

This assembly is compatible with a broad range of automotive fluids including gasoline (race and pump), diesel, transmission fluid, engine oil, hydraulic fluid, coolant and vacuum lines for gauges or boost systems. The materials were selected to resist chemical attack common to fuel and lubricants while preserving flexibility. However, always confirm compatibility with specialty chemicals before long-term use.

• Suitable for: fuel supply, fuel return, oil feed, transmission cooler and turbo cooler lines.
• Compatible with race gas, diesel, transmission fluid, oil and hydraulic fluids.
• Also works for vacuum lines and fuel gauge lines.
• Not intended for unknown aggressive chemicals without verification.

What fittings and lengths are included — how does installation look?

The kit includes 25 feet of 6AN hose (0.31" inner diameter, 0.56" outer diameter) plus ten swivel aluminum 6AN hose ends and two clamp separators to tidy runs. Fittings are provided in straight, 45°, 90° and 180° swivel styles to minimize twisting during tightening and to ease routing in tight spaces. With the included fittings and separators you can build multiple runs or replace damaged lines without sourcing extra parts.

• Hose length: 25 feet, ID 0.31" / OD 0.56" for versatile routing.
• Fittings: 10pcs 6AN swivel ends (4 straight, 2×45°, 2×90°, 2×180°).
• Extras: 2 hose separator clamps to secure parallel lines.
• Fittings made from lightweight aluminum alloy for corrosion resistance.

How do I maintain and protect these lines for long life?

Keep the braided hose free of chafing and avoid sharp edges that can abrade the nylon braid. Inspect fittings and hose runs periodically for leaks, hardening, or compression near clamps; re-torque fittings after initial heat cycles. Replace any section that shows swelling, cracking, or fuel smell to maintain safety and reliability.

• Inspect regularly for abrasion and leaks, especially after first heat cycles.
• Use provided separators and proper clamps to prevent chafing on metal parts.
• Avoid contact with extreme heat sources; route away from exhaust where possible.
• Replace sections showing damage rather than attempting patch repairs.

Who is this for: This EVIL ENERGY 6AN Fuel Line Kit suits performance tuners, race teams, and DIY mechanics who need a durable, flexible 25-foot solution for fuel, oil, transmission cooler or vacuum lines. It’s ideal for projects requiring multiple fittings and varied swivel angles—such as custom fuel systems, turbo plumbing, or transmission cooler reroutes—where dependable pressure ratings and corrosion-resistant materials are essential. If you require certified plumbing for specialized chemicals or aviation use, confirm suitability with the fluid manufacturer before installing.
