Fuelab Regulator Adjustable Electronic (1) -8 inlet (1) -8 return Black

Fuelab Adjustable Electronic Fuel Pressure Regulator -8AN Inlet/Return Black | 25-90 PSID Adjustable Range | EFI Fuel Pressure Regulator

Overview

The Fuelab Adjustable Electronic Fuel Pressure Regulator is a precision-engineered component designed to provide accurate and responsive fuel pressure control for EFI systems. Featuring an 8AN inlet and return fitting, this regulator offers a wide adjustable pressure range of 25 to 90 PSID, making it suitable for a variety of fuel delivery setups. It is ideal for Subaru enthusiasts and tuners seeking consistent fuel pressure management to support high-performance builds or upgraded fuel systems.

Built with a patented demand-based flow control technology, this regulator anticipates changes in fuel demand before fluctuations in rail pressure occur, delivering quick and stable fuel pressure response akin to mechanical regulators but with the added benefits of electronic control. Constructed from billet aluminum with a durable black anodized finish meeting military MIL-A-8625 Type II standards, it combines robust build quality with precise adjustability via a fine thread pitch mechanism.

Compatible with gasoline, diesel, methanol, and ethanol fuels, this regulator integrates seamlessly with Fuelab Prodigy fuel pumps and select Fuel Pump Controllers, offering independent operation without the need for additional control boxes or calibration. For Subaru owners, this means reliable fuel pressure regulation that supports tuning flexibility and consistent engine performance under varying load conditions.
