EVIL ENERGY 20AN Fuel Line Kit
Brand: EVIL ENERGY
Features: 20AN braided fuel line kit suitable for transmission oil cooler lines, fuel return and supply lines, coolant hoses, vacuum lines, and more. The nylon and stainless braided hose handles a range of fluids including transmission fluid, oil, race gas, vacuum, hydraulic fluid, and diesel. Maximum working pressure: 350 psi; bursting pressure: 1000 psi. Temperature range: -22°F to 248°F. Minimum bend radius: 203.2 mm. Design supports high-flex routing with durable construction for automotive applications.
EVIL ENERGY 20AN Hose End Fitting 45 Degree Swivel
Brand: EVIL ENERGY
Features: Aluminum 6061-T6 body with a 20AN thread (1 5/8-12 UNF). Swivel capability for flexible hose routing and leak reduction. The 37-degree sealing angle on the AN side supports secure connections with nylon or stainless braided hoses. Suitable for high-performance fuel and oil systems requiring reliable swivels.
Podavelle 20AN 90 Degree Elbow Swivel
Brand: Podavelle
Features: 90-degree AN20 elbow, welded-on bung joint, and lightweight 6061-T6 billet aluminum with an anodized finish. One-piece design minimizes leakage points and improves flow. Compatible with stainless braided and nylon braided hoses, but not with push-lock or PTFE hoses. Designed for durable, corrosion-resistant performance in fuel and oil lines.
AC PERFORMANCE 20AN 90 Degree Swivel
Brand: AC PERFORMANCE
Features: 20AN 90-degree hose end with a 1-5/8-12 UNF thread. Lightweight 6061-T6 aluminum and black anodized finish. Reusable hose ends with durable construction for repeated assembly and reliable sealing in compact engine bays where space is constrained.
Autofit 20AN Line Kit
Brand: Autoutfit
Features: 5-foot braided hose with AN fittings, including 90-degree, 45-degree, and straight adapters. The hose is compatible with fuel and oil lines and designed for durable long service life. Aluminum fittings are anodized for strength and corrosion resistance, and the kit aims to simplify complex routing in performance builds.
Buying Guide: Key Purchase Considerations And Comparisons
- Material and finish: Aluminum 6061-T6 bodies with black or anodized finishes offer corrosion resistance and light weight. Choose fittings designed for automotive fluids like fuel, oil, and coolant.
- Fitting angles and compatibility: Consider 90-degree, 45-degree, and straight options to fit your engine bay routing. Ensure the hose end threads match your hose, typically 20AN (1 5/8-12 UNF).
- Hose compatibility: Nylon braided versus stainless braided hoses perform differently in terms of heat resistance, DU resistance, and flexibility. Confirm the kit supports your intended fluids (fuel, transmission fluid, coolant, etc.).
- Pressure ratings: Look for higher working pressures than your system’s operating pressure. Typical 20AN assemblies support up to several hundred psi for racing or boosted applications.
- Leak prevention: One-piece or welded bung designs reduce leakage risk. Swivel ends help avoid kinking and improve flow at tight angles.
- Installation considerations: Weld-on bungs require welding skills and proper mounting. Pre-measured lengths (like 5-foot hoses) simplify routing, but verify fitment for your specific vehicle layout.
- Durability and reliability: Seek brands with documented seals and O-rings, temperature ranges suitable for your climate, and compatibility with the fluids you plan to run.
- Maintenance and replacement: Reusable hose ends reduce replacement costs, but ensure the fittings are designed for repeated disassembly and reassembly without degrading seals.
The selections above provide a mix of full kits and individual components to suit various project needs—from a complete EVIL ENERGY kit with high versatility to solid weld-on options from Podavelle and Autoutfit. Each item emphasizes reliable aluminum construction, secure sealing, and flexible routing to address the common constraints of performance vehicle builds. When selecting, match your hose type, desired angles, and operating environment to maximize both safety and efficiency.
