- 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.
- Avoid diesel fuel and nylon braided lines with E85 (use PTFE-lined hoses for E85).
- Always use sealant tape on NPT ports to prevent fuel leaks.
- Variant 1's 6AN to M12x1.25/M14x1.5 fittings are not for regulator installation.
Why Choose EVIL ENERGY EFI Fuel Pressure Regulator?
1. Durable, Performance-Proven Build
- 6061-T6 aluminum alloy resists corrosion and engine bay heat (up to 250°F), ensuring long-term reliability.
- Bypass return design prevents pressure spikes during acceleration/boost, protecting injectors and fuel rails.
2. Tailored to Your Build's Needs
- 3 variants cover all EFI scenarios: daily driving (30-70PSI), flexible modifications (20-75&75-120PSI), high-performance racing (30-140PSI).
- Replaceable springs (Variant 2/3) let you upgrade pressure without buying a new regulator.
3. All-in-One Kit Saves Time & Money
- Each variant includes all necessary parts (fittings, gauge, tape, tools) — no extra purchases for standard installation.
- Multi-size fittings adapt to existing fuel systems, reducing custom fabrication costs.
4. Safe & Easy to Install
- Clear installation notes (e.g., NPT sealant tape, fitting usage) minimize mistakes.
- Professional installation recommended for high-pressure to ensure optimal tuning and safety.
The EVIL ENERGY 1060 Aluminum Fuel Line Kit is a lightweight, durable solution for high-pressure automotive fluid systems. Whether you're routing fuel, transmission oil, or air, this 25FT hard line offers excellent corrosion resistance, heat transfer, and flexibility. Rated to 700 PSI working pressure and 2000 PSI burst, it's ideal for E85, diesel, gas, or AC retrofits. The kit includes essential tools—cutter, bender, deburring tool—so you can shape and install the line with ease. Perfect for LS swaps, restorations, or performance upgrades.
