Description

Your factory regulator works fine. It just has nowhere to bolt once the OEM rail comes off.

The Radium Engineering FPR adapter, 8AN ORB with 7mm bore and 39mm spacing, M6 lets an OEM fuel pressure regulator be reused on an aftermarket fuel rail instead of thrown away. It threads into any fuel rail with an 8AN ORB female port and enough surrounding space, presents M6x1.0mm mounting for the regulator on a 39mm hole spacing, and lets the unit be clocked to whatever orientation the engine bay demands. Machined from billet 6061 aluminum and anodized.

Features

  • Fitting threads: 8AN ORB male
  • FPR threads: M6x1.0mm
  • 39mm mount hole spacing, 7mm bore
  • Clocks the regulator to any orientation
  • Billet 6061 aluminum, anodized

The Details

Three numbers decide whether an adapter fits your regulator: bore, mount hole spacing, and thread size. This one is 7mm bore, 39mm straight spacing, M6, which is what separates it from the 20-0595 at 7mm bore with offset 39mm spacing. Both cover Honda regulators but they are not interchangeable, so match your part rather than the engine family. Your fuel rail must have an 8AN ORB female port with room around it for the regulator body to sit.
