EVIL ENERGY 6AN Fuel Line Kit 20ft Black — Nylon‑Braided CPE Hose, 750 PSI with 10 Swivel Fittings

EVIL ENERGY 6AN Fuel Line Kit is a 20-foot CPE rubber inner, 304-steel-braided, nylon outer hose set with 10 aluminum 6AN swivel fittings for fuel, oil, coolant and vacuum lines.

This kit bundles a complete 6AN fuel and fluid-routing solution in a single package: a 20-foot length of 6AN braided hose (0.31" ID, 0.56" OD) rated for 750 psi working pressure and fittings in straight, 45°, 90° and 180° swivel styles. Built for automotive and motorsport environments, the hose construction combines a CPE rubber core with a 304-steel reinforcement layer and a nylon outer braid for abrasion resistance and reliability across a broad temperature range. The included clamps and ten swivel hose ends make it straightforward to build custom lines for fuel supply, return, oil feed, or coolant runs.

How durable and pressure-capable is this 6AN braided hose for automotive use?

The hose is engineered for demanding service: CPE rubber inner tubing resists many automotive fluids, a 304 stainless-steel wire braid provides structural strength, and a nylon outer braid adds abrasion protection. With a maximum working pressure of 750 psi and a burst pressure around 2250 psi, it suits many high-pressure feed and return applications when assembled correctly.

• Inner material: CPE rubber compatible with fuels, oils and coolant
• Reinforcement: 304 stainless-steel wire braid for strength
• Outer protection: Nylon braid for abrasion and wear resistance
• Pressure ratings: 750 psi working, ~2250 psi burst

What fittings and hardware come with the kit, and how do they simplify installation?

The kit includes 10 aluminum 6AN swivel hose ends arranged for versatile routing: straight, two 45° and two 90° to navigate tight spaces, plus two 180° ends for U-turn connections. Each fitting swivels to help prevent hose twisting during assembly, and two hose separator clamps help secure lines along chassis or engine mounts for neat, vibration-resistant routing.

• 10 swivel hose ends: 4 straight, 2×45°, 2×90°, 2×180°
• 2 hose separator clamps for tidy, secure mounting
• Aluminum alloy fittings reduce weight and resist corrosion
• Hose end swivel action eases alignment and prevents kinking

Which fluids and temperatures is the hose compatible with?

The CPE inner tube and construction make the hose suitable for a wide range of automotive fluids, including gasoline (race gas), diesel, engine oil, transmission fluid, hydraulic fluid, and coolant in many applications. The specified operating temperature range spans roughly -22°F to 248°F, covering typical engine-bay extremes and street or track conditions.

• Compatible with: fuel, diesel, transmission fluid, engine oil, hydraulic fluid, coolant, vacuum lines
• Temperature range: -22°F to 248°F for typical automotive environments
• Not intended for use with unknown aggressive chemicals without testing
• Verify fluid compatibility for prolonged exposure or specialty fuels

How do I size and use the hose for my project?

This kit's inner diameter is 0.31" (6AN), making it appropriate where 6AN fittings and clearances are specified. Cut to length, attach the included swivel hose ends using the proper assembly method, and secure lines with the provided separator clamps. Always double-check sealing, torque and leak-tight assembly before putting the system under pressure.

• Hose ID: 0.31" (6AN standard), OD: 0.56"
• Total hose length: 20 feet for multiple runs or long routing
• Use proper cutting tools and assembly technique for leak-free joins
• Pressure-test the assembled system before regular use

Who is this for: EVIL ENERGY’s 6AN Fuel Line Kit is aimed at automotive enthusiasts, fabricators, motorsport teams and DIY mechanics who need a flexible, durable 6AN-rated hose and a selection of swivel fittings for fuel, oil or coolant lines. It’s particularly useful for custom installations where routing flexibility, abrasion resistance and a compact fitting set are important. If you require SAE-approved or OEM-specific certified hoses for a regulated application, confirm specifications with your regulator or vehicle builder before installation.
