EVIL ENERGY 4AN Fuel Line Kit — 10FT Black Nylon-Braided CPE Core with Aluminum Swivel Fittings

EVIL ENERGY 4AN Fuel Line Kit is a 10-foot, CPE-core nylon-braided fuel hose assembly with aluminum 4AN swivel fittings and clamps designed for high-pressure fuel, oil, and coolant routing.

This complete 4AN hose and fitting kit gives you a robust route for fuel supply and return, transmission cooler lines, oil feed, vacuum and sensor lines, or turbo cooler plumbing. Built with a CPE inner core, 304 stainless wire braid and nylon outer braid, plus anodized aluminum swivel ends, the set is engineered to balance flexibility, abrasion resistance and serviceable connections for automotive and motorsport use.

What components are included in the kit?

The kit contains the hose plus a selection of fittings and clamps so you can build multiple runs without sourcing extra parts. Standard swivel ends and adapters are included to let you orient connections in tight or angled spaces.

• 10 ft of 4AN braided hose (inner diameter 0.22" / outer diameter 0.44")
• 10pcs 4AN swivel hose ends: 4 straight, 2 × 45°, 2 × 90°, 2 × 180°
• 6 hose separator clamps for secure routing
• 2 × 4AN-to-4AN fittings for inline connections

How does the hose hold up to pressure, temperature and fluids?

The assembled hose and fittings are tested for typical automotive operating envelopes and offer a high safety margin versus daily-use pressures. Materials were selected to resist common fuels and lubricants while tolerating heat in engine bays and cooling circuits.

• Maximum working pressure: 750 psi; burst pressure: 2250 psi
• Operational temperature range: -22°F to 248°F (-30°C to 120°C)
• Compatible with gasoline, race gas, diesel, oil, transmission fluid, hydraulic fluid and vacuum applications

How easy is installation and routing with this 4AN kit?

The aluminum swivel fittings let you rotate and angle connections without twisting the hose, simplifying tight installations. The kit includes multiple angled ends and clamps so you can custom-route runs and secure them to chassis or manifolds.

• Swivel hose ends allow final alignment after installation
• Angled fittings (45°, 90°, 180°) reduce stress at bends and save space
• Included separator clamps help prevent chafing and streamline tidy routing

What materials and construction features matter for longevity?

This hose uses a layered build to combine chemical resistance with mechanical strength and abrasion protection. Fittings are aluminum alloy for light weight, and the stainless wire braid supports burst resistance while the nylon cover guards against cuts and UV exposure.

• CPE (chlorinated polyethylene) inner tube for chemical compatibility
• 304 stainless steel wire braid for burst strength
• Nylon outer braid for abrasion and environmental protection
• Aluminum alloy swivel fittings for corrosion resistance and low weight

Who this is for: This EVIL ENERGY 4AN fuel line kit suits DIY mechanics, race teams, tuners and fabricators who need a modular, serviceable 4AN plumbing solution. It works well for building fuel supply and return systems, oil or transmission cooler lines, turbo cooler plumbing, vacuum lines and sensor feeds where flexible, high-pressure hose and adjustable swivel ends are preferred.
