EVIL ENERGY 4AN Nylon-Braided Fuel Line Kit, 20ft Black CPE Hose with Aluminum Swivel Fittings, 750 psi

EVIL ENERGY 4AN Fuel Line Kit is a 20-foot nylon-braided CPE hose system with aluminum 4AN swivel fittings designed for high-pressure fuel, oil and coolant routing in automotive and racing applications.

This kit combines a chemical-resistant CPE inner hose, a 304 stainless wire layer and a durable nylon outer braid with a set of aluminum swivel ends to create a flexible, pressure-rated line useful for supply, return, cooler and vacuum runs. The assembly tolerates a wide temperature band and high working pressures, making it suitable for performance vehicles, marine projects and custom plumbing where reliability and routing flexibility matter.

How tough is the hose for high-pressure applications?

The hose is engineered for demanding environments: it has a maximum working pressure of 750 psi and a bursting pressure around 2250 psi, giving a strong safety margin for most automotive uses. The combination of a CPE rubber core, 304 stainless wire reinforcement and nylon braid provides resistance to kinking while maintaining structural integrity under pressure.

• Working pressure: 750 psi
• Burst pressure: ~2250 psi
• Reinforcement: 304 stainless steel wire plus nylon braid
• Inner material: chemical-resistant CPE rubber

Which fluids and temperatures can the kit handle?

The hose and fittings are compatible with a broad set of automotive fluids including gasoline, race fuels, diesel, transmission fluid, engine oil and many coolants. Temperature performance spans from about -22°F up to 248°F, covering cold starts through hot engine bays and many performance environments.

• Compatible fluids: fuel, oil, transmission fluid, coolant, diesel, vacuum lines
• Temperature range: -22°F to 248°F (-30°C to 120°C approximately)
• Suitable for fuel return, supply, oil feed and cooler lines
• Not for unlisted aggressive chemicals without testing

What fittings and lengths are included in the package?

The kit ships with 20 feet of 4AN braided hose and a balanced assortment of 4AN swivel hose ends to cover common routing needs. You also get two hose separator clamps to organize runs and prevent chafing in tight installations.

• Length: 20 feet of 4AN hose (0.22" ID, 0.44" OD)
• Fittings: 10 aluminum 4AN swivel ends (4 straight, 2×45°, 2×90°, 2×180°)
• Accessories: 2 hose separator clamps included
• Fitting material: lightweight aluminum alloy

Who this kit is for: racers, tuners, custom fabricators and hobbyists who need a flexible, pressure-rated 4AN line for fuel, oil or cooler plumbing will benefit from this EVIL ENERGY kit. It’s ideal for retrofit projects, oil and fuel cooler plumbing, turbo oil returns and any application where a resilient, braided hose assembly and an assortment of swivel angles save installation time and improve routing. If you require EPDM/other specific rubber or certified fittings for regulated systems, verify compatibility before installation.
