EVIL ENERGY 8AN Fuel Line, 20FT
The EVIL ENERGY 8AN Fuel Line features a CPE inner layer, a 304 stainless steel wire layer, and a nylon outer braid for robust durability. It is designed to withstand high pressure with a maximum working pressure of 750 PSI and a bursting pressure around 2250 PSI. Temperature tolerance ranges from -22°F to 248°F, suitable for fuel, oil, transmission fluid, vacuum, and diesel lines in performance applications. This 20-foot braided hose provides ample length for routing in tight engine bays.
EVIL ENERGY 8AN Fuel Line Kit, 8AN Nylon Braided 20FT
This 8AN fuel line kit includes a 20-foot nylon-braided hose that is widely used for transmission oil cooler lines, fuel supply and return lines, coolant hoses, and vacuum lines. The hose supports a maximum working pressure of 750 PSI and bursting pressure of 2250 PSI, with a temperature range of -22°F to 248°F. Compatibility spans transmission fluid, oil, race gas, vacuum, hydraulic fluid, diesel, and regular fuel, making it versatile for many performance setups.
EVIL ENERGY 8AN Fuel Line, 5FT
This 5-foot 8AN braided fuel hose uses a CPE inner layer with a 304 steel wire and nylon outer braid. It mirrors the same high-pressure capabilities as the longer EVIL ENERGY lines, with a maximum working pressure of 750 PSI and a bursting pressure of 2250 PSI. The temperature range remains from -22°F to 248°F, making it suitable for high-temperature fuel and oil routes in compact engine bays where length is at a premium.
Ucreative 8AN CPE Fuel Hose, 10FT
The Ucreative 8AN CPE fuel hose pairs CPE synthetic rubber with nylon braiding, and includes multiple fittings in the kit (straight, 45-degree, 90-degree swivel ends, and a hose separator clamp). Hose dimensions are ID 0.43 inch (11mm) and OD 0.64 inch (16.25mm). Length is 10 feet. Note the fittings are not compatible with PTFE hoses, E85, or rubber hoses. The kit-style approach is ideal for users who want a complete install solution for a new routing plan.
EVIL ENERGY 8AN PTFE Fuel Hose Line, 10FT
The EVIL ENERGY PTFE 8AN hose uses a PTFE braided lining with an outer braid designed for high-heat fuel systems. The ID is 0.39 inch and the OD is 0.55 inch, with a 10-foot length. Its temperature tolerance ranges from -76°F to 446°F and a maximum working pressure of 1500 PSI, with bursting pressure around 4500 PSI. Compatible with a wide variety of fuels and fluids, including E85 and biodiesel, this hose is ideal for high-performance, high-temp applications that demand excellent chemical resistance.
Buying Guide: 8AN Hose Purchase Considerations
- Compatibility: Verify which fluids your system carries (gasoline, diesel, oil, transmission fluid, coolant) and ensure the hose material is compatible with those fluids.
- Pressure and Burst Resistance: Select hoses with a suitable maximum working pressure and bursting pressure for your setup. Higher performance engines may require hoses rated well above typical fuel pressures.
- Material and Construction: CPE, nylon braided, and PTFE-lined hoses offer different balances of flexibility, abrasion resistance, and chemical compatibility. PTFE variants excel in high-heat and chemical environments but can be stiffer to route.
- Temperature Range: Consider the engine bay temperature and potential heat exposure. Extreme temperatures can affect hose life and seal integrity.
- Length and Bend Radius: Measure available space and select hose lengths that avoid sharp bends. Minimum bend radius guidance helps prevent early failure.
- Fittings and Ends: Ensure fittings match your barbed, AN, or swivel interfaces. Some kits include a full assortment of ends, which simplifies installation but check compatibility with PTFE hoses if mixing materials.
- Installation Considerations: Use proper clamps, routing away from hot exhaust components, and avoid kinking. Some hoses require specific crimp or compression fittings for a secure seal.
- Maintenance: Regularly inspect hoses for signs of wear, cracking, or swelling, especially in high-heat or high-pressure zones. Replace aging hoses proactively to prevent leaks.
- Regulatory and Safety: Follow vehicle manufacturers’ guidelines and local regulations when upgrading fuel and oil lines, and ensure compatibility with any emissions components.
In summary, the best 8AN hose choice depends on your project’s temperature, pressure, and fluid needs. For extreme heat and chemical resistance, PTFE-lined hoses provide robust performance. For flexible routing and broad compatibility, nylon braided or CPE hoses offer strong value. Kits that include a variety of fittings simplify installation, while standalone hoses allow precise customization. Selecting the right combination will help maintain reliability and performance in demanding automotive applications.
