This fuel rail adapter makes it easy to install an external adjustable fuel pressure regulator on the factory fuel rail of a wide range of Mazda, Nissan, and Subaru engines. The adapter mounts directly to the end of the factory fuel rail and provides an AN6 connection, making it ideal for upgrading to an aftermarket EFI fuel system.
The adapter is CNC-machined from aluminium and anodized for excellent corrosion resistance and long service life. Its precision-machined design ensures a leak-free and reliable installation while allowing the use of external fuel pressure regulators from AEM, Nuke Performance, DeatschWerks, Turbosmart, and other leading manufacturers.
The fuel rail adapter fits a range of popular turbocharged Mazda, Nissan, and Subaru engines and is an excellent choice for motorsport, tuning, and EFI upgrades where the factory return system is replaced with an adjustable fuel pressure regulator.
