Radium FPR adaptors are anodised billet 6061 aluminium fittings that allow an OEM fuel pressure regulator (FPR) or fuel pulse damper (FPD) to be reused on a fuel rail other than the one it was designed for. They suit virtually any fuel rail with an 8AN ORB female port and enough surrounding space for the regulator, and every fitting allows the unit to be clocked into the correct orientation.
This version accepts OEM components with an 11mm bore and 32mm mounting hole spacing, using M5x0.8mm fasteners.
Key Features
- Reuse OEM Components: Fit an OEM FPR or FPD to an aftermarket fuel rail
- 8AN ORB Rail Side: Suits virtually any fuel rail with an 8AN ORB female port
- 11mm Bore / 32mm Spacing: Matches the listed OEM regulators and dampers
- M5x0.8mm Mounting Threads: For the OEM FPR/FPD mounting bolts
- Clockable: Can be clocked into the correct orientation
- Billet 6061 Aluminium: Anodised finish
Important Notes
- The OEM FPR/FPD must match both the 11mm bore and the 32mm mounting hole spacing
- The fuel rail needs an 8AN ORB female port with enough clearance around it for the FPR/FPD
