EVIL ENERGY Fuel Pressure Regulator

The EVIL ENERGY Adjustable Bypass Fuel Pressure Regulator is a critical component for fine-tuning EFI (Electronic Fuel Injection) systems, delivering precision fuel control for high-demand performance setups. Ideal for custom performance engines, fuel system upgrades, and racing vehicles, it ensures consistent fuel pressure under varying conditions—optimizing fuel delivery, engine efficiency, and overall performance.

  • Wide Adjustable Pressure Range: Tailor fuel delivery to your engine's specific needs with 3 optional ranges—20-120PSI, 30-70PSI, 30-140PSI—perfect for optimizing performance across street driving, track use, or off-road conditions.
  • Bypass EFI Design: Prevents pressure spikes and maintains stable fuel pressure even in high-load scenarios (e.g., turbo boost, rapid acceleration), ensuring reliable EFI system operation.
  • Universal Compatibility: Equipped with 6AN/10AN inlet/outlet fittings and 6AN/10AN bypass return port, it seamlessly integrates into most aftermarket and custom fuel systems—suitable for LS swaps, turbo setups, and other performance modifications.
  • Durable & Versatile Build: Crafted from high-strength aluminum, it withstands harsh engine bay conditions (heat, vibration, chemicals) for long-lasting use. Compatible with gasoline and ethanol-based fuels (including E85), offering versatility for modern performance builds.
  • Easy Installation & Tuning: Intuitive adjustment design allows quick pressure fine-tuning without complex tools; fits a wide range of applications from street cars to race cars and off-road vehicles.

Applications

  • EFI System Upgrades: Perfect for fine-tuning fuel systems in performance vehicles with EFI setups, correcting pressure inconsistencies and boosting efficiency.
  • Custom Engine Builds: Ideal for high-performance engine builds (e.g., modified muscle cars, import tuners) that require precise fuel pressure control to match power upgrades.
  • Racing & Off-Road Vehicles: Designed to meet the demanding fuel system requirements of racing engines (drag, circuit) and off-road vehicles, where stable pressure is critical for reliability.

Why Choose EVIL ENERGY Regulator?
Engineered for precision, its bypass feature eliminates pressure fluctuations, while easy adjustability and universal compatibility make it a hassle-free upgrade. Whether you're building a custom ride or upgrading an existing EFI system, it delivers consistent performance to maximize your engine's potential.

Fuel PSI Regulator. EFI -

I purchased Evil fuel pressure regulator for an EFI set up, it comes with a nice gauge extra fittings. The packaging is really nice. The regulator itself as soon as you pick it up it’s very durable. It’s very well-made. I was very impressed. It works perfect perfectly. This is a high dollar regulator at an affordable price. I would definitely recommend this product.
