VWTNI 6AN Fuel Line
Material composition combines a CPE inner liner, stainless steel wire mesh intermediary, and nylon braided outer layer, delivering a robust 10 ft length suitable for transmission oil cooler lines, vapor return, fuel supply, coolant hoses, and turbo feed lines. The ID is 0.34 inches (8.8 mm) with an OD of 0.55 inches (14 mm). It supports temperatures from -104°F to 248°F (-40°C to 120°C) and a maximum working pressure of 500 PSI, with a bursting pressure around 2000 PSI. This flexibility makes it a solid all-around option for varied automotive applications.
3 FT 6AN 3/8″ ID Fuel Line Kit
This stainless steel braided CPE fuel hose is designed for racing and heavy-duty use, suitable for transmission oil coolers, fuel lines, coolants, carburetor hoses, turbo lines, and oil feeds. It handles up to 1000 PSI working pressure and up to 6000 PSI bursting pressure, with a temperature range from -40°F to 257°F (-40°C to 125°C). The kit includes a universal 3 ft hose and two swivel ends, with an inner diameter of 3/8″ (10.5 mm) and outer diameter of 5/8″ (17.5 mm). Check compatibility with your specific system before installation.
HEROFFIX 1Pcs 1/8 Fuel Line
This 1/8″ ID, 5 ft NPR rubber nylon braided fuel hose is designed for varied automotive uses, including coolant, fuel, diesel, oil, hydraulic fluids, and turbo systems. Constructed from NPR rubber and nylon braid, the hose prioritizes durability and resistance to wear, helping maintain system integrity under typical operating conditions. It serves as a compact option for tight engine bays or where smaller ID lines are needed.
EVIL ENERGY 6AN Nylon CPE 5FT
This 6AN braided fuel hose features a CPE rubber inner layer, a 304 stainless steel wire layer, and a nylon outer braid. It offers a maximum working pressure of 750 PSI, bursting at 2,250 PSI, and a temperature range from -22°F to 248°F. The hose is widely compatible with transmission fluid, oil, race gas, vacuum, hydraulic fluid, diesel, and other fuels, making it suitable for high-performance builds and varied fuel systems.
EVIL ENERGY 6AN Nylon CPE 20FT
An extended 20 ft length version of the 6AN nylon CPE line, this hose maintains the same internal CPE liner, 304 steel wire, and nylon outer braid construction with 750 PSI working pressure and 2,250 PSI bursting pressure. It retains compatibility with transmission fluid, oil, race gas, vacuum, hydraulic fluid, diesel, and other fuels, suitable for longer runs in engine bays, drag cars, or race ambulatory vehicles where extended length is preferred.
EVIL ENERGY 6AN PTFE Fuel Hose
This 6AN PTFE fuel line provides a ID of 0.31 inches and OD of 0.43 inches with a 10-foot length. It features installation instructions and a wide temperature range from -76°F to 446°F (-60°C to 230°C), a maximum working pressure of 1500 PSI, and a bursting pressure of 4500 PSI. Bend radius is 3.5 inches. It is compatible with transmission fluid, diesel, biodiesel, engine oil, E85, methanol, water, and general fuels, making it a strong choice for high-performance or specialized fuel systems requiring PTFE containment.
6AN Fuel Line Kit – 20FT
This kit includes 20 ft of 6AN braided fuel line with multiple swivel hose ends (straight, 45, 90, and 180 degrees). It’s designed for widespread use, including transmission oil cooler lines, fuel return and supply lines, coolant hoses, and turbo/ oil feed lines. The outer braid uses silver nylon stainless steel construction over a CPE inner liner. It’s broadly compatible with fuel, lube, ethanol, coolant, and air, with notable suitability for racing cars and motorcycles, but not intended for E85 in most configurations.
EVIL ENERGY 8AN Nylon CPE 5FT
This 8AN braided fuel hose employs a CPE inner layer with a stainless steel wire and nylon outer braid. It shares the same broad compatibility with transmission fluid, oil, race gas, vacuum, hydraulic fluid, diesel, and more. With high-pressure tolerance and robust materials, it supports more demanding setups that require larger ID/AN connections and higher flow to feed performance components.
Buying Guide
- Playing field and compatibility: Choose hoses with inner liners compatible with your fluid (gasoline, diesel, coolant, oil, transmission fluid) and that can withstand the operating temperatures of your engine bay.
- Strength and safety: Look for multi-layer constructions (inner liner, steel wire or mesh, and outer braid) that provide resistance to pressure, bursting, and abrasion in harsh environments.
- Pressure and temperature ratings: Ensure working pressure and bursting pressures meet or exceed your system’s requirements. PTFE-lined hoses tend to offer higher chemical and heat resistance but may be stiffer and more expensive.
- Length and routing: Plan hose lengths to minimize sharp bends and excessive slack. PTFE options often require careful bending due to lower flexibility at higher pressures.
- Fittings and compatibility: Confirm that fittings (AN6, AN8, etc.) match your device and that included end adapters suit your installation. Some kits include swivel ends for easier routing.
- Intended use: For street cars, standard nylon/CPE braided lines provide reliable performance for fuel and coolant. For race applications, higher pressure ratings and PTFE lines may be preferred.
- Maintenance and inspection: Regularly inspect hoses for cracking, wear, or swelling, especially near clamps and routing points, and replace if any damage is observed.
- Installation considerations: Follow manufacturer torque specs where applicable, and use compatible sealants or clamps designed for braided hoses to avoid leaks and ensure a secure fit.
