Description
xPQY's adjustable EFI fuel pressure regulator kit is built from billet aluminum and designed for reliable fuel delivery in modern EFI systems. It features AN8 feed port, AN6 return port, a 1/8" NPT gauge port, and a vacuum boost line connection to support accurate readings and responsive pressure control. The regulator can be tuned across a wide range from 3 to 70 psi, letting you dial in your target fuel curve as your engine needs evolve. The internal springs provide two primary ranges—3-20 psi for light throttle and drivability, and 45-70 psi for higher-load applications—giving you tuning options without swapping components. The top-mounted adjustment bolt makes on-car tuning straightforward, while the end cap option allows you to simplify plumbing if you only require a single feed. With E85 compatibility, this regulator is ready to support flex-fuel setups when paired with proper lines and fittings. The included installation instructions walk you through the setup, and the compact billet design fits a range of engine bays while maintaining a clean, professional look.
