Description

1G DSM regulators use a mount spacing nothing else does, which is why this adapter exists.

The Radium Engineering FPR adapter, 8AN ORB with 16mm bore and 50mm spacing, M6 lets a first generation DSM fuel pressure regulator be reused on an aftermarket fuel rail. It threads into any fuel rail with an 8AN ORB female port and enough surrounding space, presents M6x1.0mm mounting on a 50mm 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
  • 50mm mount hole spacing, 16mm 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 16mm bore, 50mm spacing, M6, which covers first generation DSM 4G63 regulators. Second generation DSM and Evo IV through IX regulators use 39mm spacing instead and need the 20-0302. The generation split matters more than the engine code here, since both are 4G63. Your fuel rail must have an 8AN ORB female port with room around it for the regulator body.
