The Fuel Press Reg In-L Mini EFI 25-90psi 6AN/6AN from FUELAB Fuel Systems is a compact inline fuel pressure regulator designed for EFI fuel system tuning and engine modifications. This component is essential for builders and mechanics who require precise fuel pressure control across a wide operating range, whether upgrading to larger fuel injectors or fine-tuning carbureted-to-EFI conversions.
The adjustable 25–90 psi range accommodates everything from stock fuel system pressures to high-flow performance applications. Built with FUELAB's reputation for reliability, this mini inline regulator uses a direct-acting poppet design to maintain consistent fuel pressure regardless of fuel flow demand or engine load conditions. The dual 6AN inlet and outlet ports ensure compatibility with modern fuel line sizing and support higher flow rates without restriction.
Its compact footprint and lightweight construction allow flexible mounting in engine bays where space is limited. This regulator benefits fuel system installers, engine tuners, and performance shops supporting naturally aspirated and boosted applications requiring independent pressure control. Installation involves simple inline placement between the fuel pump and rail.
