Product Reviews
EVIL ENERGY 6AN PTFE Fuel Line Kit 20FT
The kit features a PTFE-lined fuel hose with a 6AN (5/16″ ID) specification. Working temperature ranges from -60°C to 230°C (-76°F to 446°F), supporting a maximum working pressure of 1,500 PSI and a bursting pressure around 4,500 PSI. It is suitable for automotive fuels, lubricants, and coolants. The kit length is 20 feet, providing ample length for multiple fuel runs or EFI feed lines. The included hose is designed for high-temperature environments typical of E85 use, aiding reliability in performance applications.
EVIL ENERGY 6AN PTFE LS Swap EFI Kit 26FT
Designed for LS engine swaps and EFI systems, this 26-foot PTFE hose kit uses 6AN fittings with a 5/16″ ID. It shares a similar temperature tolerance as the shorter kit, from -60°C to 230°C, with 1,500 PSI working pressure and 4,500 PSI bursting pressure. It includes fittings and components suitable for high-performance LS-based builds. This kit helps create clean, reliable fuel rails and lines for E85-compatible engines, reducing the risk of ethanol-related swelling or degradation in hoses.
Medoon 6AN PTFE Fuel Line Kit 26FT
Medoon’s 26-foot kit includes 26 feet of AN6 PTFE hose, plus 12 hose end fittings, four quick disconnects, six hose separators, and multiple adapters. The hose features a 3/8″ inner diameter and a 0.465″ outer diameter, with a working temperature range from -60°C to 230°C and pressures up to 3,000 PSI (burst 10,000 PSI). It is designed for broad EFI LS applications, including LS engine swaps and turbo installations, and supports E85-compatible fuels, lubricants, and coolants with robust chemical resistance.
EVIL ENERGY 8AN PTFE Fuel Line Kit 20FT
This kit uses an 8AN (13/32″ ID) PTFE hose with a 20-foot length. It includes matching high-strength fittings for high-pressure systems, making it suitable for ethanol-rich fuels like E85 and other alcohol-based fuels. The hose is rated for -60°C to 230°C and 1,500 PSI working pressure with 4,500 PSI bursting pressure, offering strong resistance to ethanol-induced degradation and heat in high-performance applications. The kit is ideal for longer runs from fuel tanks to rails or surge tanks in performance builds.
EVIL ENERGY 6AN 3/8″ PTFE LS Swap EFI Kit 25FT
This 25-foot LS swap EFI kit uses 6AN fittings with a 3/8″ ID, designed for LS-based engines and other EFI systems requiring robust, ethanol-compatible lines. Temperatures range from -60°C to 230°C, with a maximum working pressure of 1,500 PSI and bursting pressure near 4,500 PSI. The kit provides a comprehensive set of components for building or upgrading a high-performance fuel line network for E85-compatible engines, with strong resistance to ethanol solvents and heat exposure.
Buying Guide: Key Considerations for E85 Fuel System Kits
When selecting an E85-compatible fuel system kit, consider the following factors to ensure compatibility, safety, and performance:
- Fittings and hose size: Verify AN size (6AN, 8AN, etc.) and inner diameter to match your fuel rails, pump, and return lines. Mismatched sizes can create flow restrictions or leaks.
- Material and compatibility: PTFE-lined hoses are preferred for ethanol fuels due to chemical resistance and reduced permeation. Ensure hoses tolerate ethanol blends without swelling.
- Temperature and pressure ratings: Look for wide operating temperatures (-60°C to 230°C) and high working pressures (≥1,000 PSI) to handle high-performance fuel systems and potential surges.
- Length and routing: Choose lengths that minimize splices and potential leaks. Plan routing to avoid heat sources and movement hazards while allowing for maintenance access.
- LS swap vs. standard EFI: LS swap kits are tailored for LS engines and may include fittings optimized for specific EFI configurations; confirm compatibility with your engine platform.
- Installation components: Some kits include fittings, clamps, quick disconnects, and wrenches. A complete kit reduces additional shopping and mismatch risk.
- Ethanol content and future use: If you plan to switch blends or fuels, select hoses with robust chemical resistance and proven E85 compatibility.
For buyers focusing on E85 systems, these kits offer reliable PTFE hoses and durable fittings designed to withstand ethanol exposure and elevated temperatures typical in performance environments. Always consult your engine builder or mechanic for installation guidance and to ensure all components work together safely and efficiently.
