20-0459 FPD Adapter, 8AN ORB, 27mm Bore
The OEM VR38DETT fuel pulse damper can be reused with this adapter. These can install into any fuel rail port provided there is adequate clearance.

NOTE: If the 20-0556-PK plumbing kit (listed above) was purchased, this adapter can be used in the spare top port, as shown below.

The OEM VQ35HR and VQ37VHR fuel pulse dampers can be reused with these adapters. One is required for each fuel pulse damper. NOTES:
1. If the 20-0469 plumbing kit (listed above) was purchased, these adapters are already included and thus, not necessary.  
2. Use the 20-0460 OEM FPD adapter for the VQ35DE engine.
3. The VQ37VHR engine is NOT compatible with any Radium aftermarket dampers. Only the OEM dampers can be used using this adapter.

These can install into any fuel rail port provided there is adequate clearance. The Nissan VQ35HR is shown below.
