The FUELAB Fuel Pressure Regulator Ultralight EFI 25-90 PSI is a precision in-line fuel pressure regulator engineered for EFI fuel systems running gasoline, diesel, E85, or methanol. This ultralight aluminum regulator delivers accurate pressure control from 25 to 90 PSI, making it suitable for both stock and modified fuel injection systems that demand reliable, consistent fuel delivery without weight penalty.
Built from black anodized aluminum, this regulator features dual 8 AN female inlet ports and a single 6 AN female return port, allowing flexible fuel line routing on custom EFI systems. The 1/8 inch NPT gauge port enables direct pressure monitoring via aftermarket fuel pressure gauges. The ultralight construction minimizes parasitic weight in the fuel system while maintaining the structural integrity required for consistent regulation across the 25–90 PSI operating range. The regulator's in-line configuration simplifies installation in engine bays with space constraints or alternative fuel cell locations.
This fuel pressure regulator is ideal for custom EFI conversions, street performance builds, and racing applications where precise fuel pressure control is critical to engine tuning and reliability. Builders working with alternative fuels—particularly E85 or methanol—benefit from the multi-fuel compatibility and the ability to set pressure independently of OEM constraints. The dual-inlet design accommodates dual-pump setups or system redundancy common in high-performance race vehicles.
FUELAB's fuel system components are recognized in the performance automotive market for precision manufacturing and consistent functionality under demanding conditions. The 25–90 PSI range covers most carbureted fuel pump pressures and modern EFI systems, providing flexibility for builders transitioning between fuel delivery technologies or tuning for specific injector flow rates and engine requirements.
