EVIL ENERGY EFI Fuel System Kit – Adjustable Fuel Pressure Regulator (6AN, 20–140 PSI) + 25FT Aluminum Coiled Fuel Line Hard Tubing (3/8-inch & 5/16-inch)

• Durable Construction: Precision-machined 6061-T6 aluminum alloy, corrosion-resistant and heat-tolerant (withstands harsh engine bay conditions), ensuring long-term reliability.
• EFI System Compatibility： Fits most vehicles' electronic fuel injection (EFI) systems; maintains stable fuel pressure for optimized combustion, performance, and fuel economy.
• Fuel Compatibility：Works with gasoline, E85, and alcohol/ethanol;（not compatible with diesel fuel）note: nylon braided fuel lines are not E85-compatible (use PTFE-lined hoses for E85).
• Bypass Return Design：Prevents pressure spikes during acceleration, boost, or high-load scenarios, protecting fuel injectors and rails from damage.
• All-in-One Kit： Each variant includes essential components (fuel pressure regulator, pressure gauge, fittings, sealant tape, tools like Allen keys); no extra purchases needed for standard installation.
• Easy Installation & Tuning： Adjust pressure via top set screw (clockwise = increase, counterclockwise = decrease); use thread sealant tape on NPT gauge port to avoid leaks; professional installation highly recommended (especially for high-pressure variants).

The EVIL ENERGY EFI Bypass Fuel Pressure Regulator is a precision-engineered component designed to maintain stable fuel pressure for EFI systems, ensuring optimal combustion efficiency, engine performance, and fuel economy. Crafted from high-strength 6061-T6 aluminum alloy, it withstands harsh engine bay conditions (heat, vibration, corrosion) and is compatible with common performance fuels (gasoline, E85, alcohol/ethanol) — making it ideal for daily drivers, modified vehicles, and high-performance builds.

30-70PSI: Daily-Driven EFI Systems
This fixed-range regulator (30-70PSI) is tailored for standard EFI vehicles, providing reliable pressure control without extra adjustments. It includes 3×6AN braided CPE fuel lines and fuel rail-specific fittings (6AN to M12x1.25 / M14x1.5), eliminating the need for separate part purchases. Perfect for commuters or mild modifications where consistent, moderate pressure is required.

20-75&75-120PSI: Flexible Tuning for Modified Builds
With two pressure ranges (via replaceable spring), this variant adapts to diverse needs: 20-75PSI for street-focused setups, 75-120PSI for more aggressive modifications (e.g., turbocharged daily drivers). It comes with multi-size ORB fittings (6AN/8AN/10AN) for custom routing and an Allen key for easy spring replacement — ideal for enthusiasts who upgrade their engine over time.

30-80&80-140PSI: High-Performance Racing & Turbo Setups
Built for high-horsepower EFI systems (e.g., drag racing, track cars), this 10AN regulator offers extended pressure range (30-140PSI via replaceable spring) and a dedicated vacuum interface for precise pressure matching under boost. It includes 9 multi-size ORB fittings (AN6/8/10 to 10AN) for complex fuel system routing, ensuring stable pressure even in extreme load conditions.
