The Radium Engineering FPD Adapter allows the OEM VQ35HR and VQ37VHR fuel pulse dampers to be reused with Radium aftermarket fuel rails. One adapter is required per fuel pulse damper. The adapter installs into any fuel rail port with adequate clearance.

Important Notes:

• If the Radium 20-0469 plumbing kit was purchased, these adapters are already included — do not purchase separately.
• For the VQ35DE engine, use the 20-0460 OEM FPD Adapter instead.
• The VQ37VHR engine is not compatible with any Radium aftermarket dampers — only the OEM dampers can be used with this adapter.
