Radium Fuel Pulse Damper Kit - Toyota Supra JZA80 MK4 (1993-2002, 2JZ-GTE)
Suits:
- 1993-2002 Toyota Supra JZA80 (MK4) — 2JZ-GTE
The Radium Engineering Fuel Pulse Damper Kit is a complete replacement for the OEM fuel pulse damper on the JZA80 Supra 2JZ-GTE engine. It also replaces the fuel feed line from the filter to the fuel rail, eliminating 4 restrictive OEM banjo fittings in the process. OEM rubber hoses are replaced with E85-safe PTFE fuel lines, and anodised aluminium adapter fittings are included for compatibility with both the OEM fuel rail and aftermarket 8AN ORB fuel rails.
The Radium FPD-R (vacuum-referenced fuel pulse damper) mounts in the OEM location using a stainless steel bracket, using the factory threaded bosses with no permanent modifications required. The vacuum reference makes it ideal for high-boost applications.
Note: The larger FPD-XR is not compatible with this kit — it would interfere with the starter motor.
