  • 20-75 & 75-120 PSI: Designed for aggressive street and modified setups in an LS Swap Fuel System Package.
  • 30-80 & 80-140 PSI: Perfect for high-horsepower racing or turbo systems; this Fuel Pressure Regulator includes a vacuum interface for full boost compatibility.
• Premium Build & Multi-Fuel Compatibility: Each Adjustable EFI Fuel Pressure Regulator is precision-crafted from 6061-T6 aluminum alloy to resist heat, vibration, and corrosion. This high-performance Fuel Pressure Regulator is compatible with gasoline, E85, and alcohol. When integrating this into your LS Swap Fuel System Package, please use a PTFE fuel line for E85 compatibility. To ensure a leak-free setup with your 300LPH External Fuel Pump, the kit includes tailored fittings (6AN/8AN/10AN ORB) for custom routing of your fuel injection lines.

Precise Fuel Pressure Regulator Methods

You can choose the installation direction of your Fuel Pressure Regulator based on your specific engine bay layout. This method allows the system to distinguish between the 'Supply' path (Red), representing active PSI, and the 'Return' path (Blue) for excess pressure bleed-off, keeping the pressure within your fuel injection lines perfectly stable.

3. Adjustable 3-16AN Fitting Wrench

• Surface Protection & High Functionality: No Complete Fuel Delivery System with Regulator is complete without the right tools for a damage-free assembly. This AN Fitting Adjustable Wrench features interchangeable hex and flat nylon jackets, allowing you to grip AN fittings across a 3-16AN range without scratching or damaging the anodized finish. As a Universal AN Fitting Tool for Fuel Lines, this AN Fitting Wrench Adjustable ensures that your fuel injection lines and evil energy fuel pump fittings remain in pristine, show-quality condition during installation.
