Radium Engineering FPR Adapter – 8AN ORB 16mm Bore 39mm Spacing M6 – Evolution 8/9 4G63

The Radium Engineering FPR Adapter – 8AN ORB, 16mm Bore, 39mm Spacing, M6 lets you retain a compatible OEM fuel pressure regulator when converting to an aftermarket fuel rail with an 8AN ORB female port. It gives the regulator a proper mounting and sealing interface without forcing you to replace a functioning factory regulator just because the rail has changed.

This version uses a 16mm regulator bore, 39mm mounting-hole spacing, and M6x1.0 threads. Radium lists it as compatible with OEM fuel pressure regulators used on Mitsubishi Evo IV, V, VI, VII, VIII and IX, along with 2G DSM Mitsubishi Eclipse and Eagle Talon 4G63 applications. The adapter is machined from anodized billet 6061 aluminum and allows the regulator to be clocked into the position that best fits the installation.
