It excels in high-pressure contexts, with a maximum working pressure of 750 psi and bursting pressure of 2,250 psi. Temperature tolerance spans -22°F to 248°F. The hose is compatible with transmission fluid, oil, race gas, vacuum, hydraulic fluid, diesel, and fuel, offering broad applicability for racing and street setups alike.
EVIL ENERGY 8AN Fuel Line Kit, 8AN Nylon Braided 20FT
The 8AN kit expands connection options for higher-performance systems, featuring a CPE inner lining, stainless steel wire layer, and nylon outer braid. It shares EVIL ENERGY’s emphasis on durability and reliability, with a maximum working pressure of 750 psi and bursting pressure around 2250 psi. Temperature tolerance runs from -22°F to 248°F. It is suitable for transmission fluid, oil, race gas, vacuum, hydraulic fluid, diesel, and general fuel lines, supporting demanding engine builds and high-heat environments.
GOIMGN 6AN Fuel Line Hose, 20FT Nylon Braided
GOIMGN’s 6AN braided fuel line uses a 3-layer construction: CPE synthetic rubber inner lining, a 304 stainless steel wire mesh middle, and a nylon braided outer cover. It withstands up to 500 psi working pressure and 2000 psi bursting pressure, with an extreme temperature range from -104°F to 248°F. Compatible with gasoline, diesel, coolant, hydraulic oil, fuel, and water, this hose suits high-performance vehicles, racing applications, and powertrain flexibility needs.
EVIL ENERGY 10AN Fuel Line Kit, 20FT Nylon Braided
The 10AN kit provides larger line diameter for increased fuel flow in high-performance builds. It comprises a CPE rubber inner layer, a stainless steel wire layer, and a nylon outer braid, with aluminum alloy fittings. Max working pressure is 625 psi, bursting pressure 1875 psi, and the temperature range is -22°F to 248°F. The kit’s broad compatibility includes transmission fluid, fuel, oil, and other race-ready fluids, making it suitable for turbocharged engines and high-performance platforms.
Buying Guide
Key purchase considerations for nylon braided fuel lines:
- AN size compatibility: Ensure the line size (6AN, 8AN, 10AN) matches the port fittings and intended flow requirements of your system.
- Inner lining and outer braid: Look for a robust inner material (CPE or PTFE) and a durable nylon outer braid with a corrosion-resistant metal layer for long-term reliability.
- Pressure ratings: Compare maximum working pressure and bursting pressure to meet your engine’s fuel pressure needs, especially in forced-induction or race settings.
- Temperature tolerance: Select lines rated for the expected operating range, including hot exhaust proximity or under-hood heat exposure.
- Compatibility: Confirm fluid compatibility (gasoline, diesel, race fuel, transmission fluid, hydraulic oil) to avoid chemical degradation.
- Length and routing: Measure required length and consider bending radii to prevent kinking and ensure clean routing in tight engine bays.
- Fittings material: Aluminum fittings are common for lightweight, corrosion resistance; ensure thread size and sealing method match your connections.
For most performance builds, opting for a kit with full-length hoses, proper fittings, and clear installation guidelines reduces setup time and helps maintain reliability across seasons. Consider the combination of AN size, material construction, and temperature and pressure specs to match your vehicle’s fuel system design and intended use.
