[30-70PSI][30-70PSI,Black]
EVIL ENERGY Fuel Pressure Regulator 6AN EFI Bypass Return Adjustable 20-140psi Black&Red - Red

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).
