Radium Fuel Pulse Damper Kit - Toyota Supra JZA80 (2JZ-GTE)

The Radium Engineering 20-1389 Fuel Pulse Damper Kit completely replaces the OEM fuel pulse damper on the Toyota Supra JZA80 2JZ-GTE. It also replaces the fuel feed line from the filter to the fuel rail, eliminating four restrictive banjo fittings.

Using 6AN hoses, the kit works with either the factory fuel rail or an aftermarket 8AN ORB rail — anodised aluminium adapter fittings for both are included. It is a great option when an aftermarket fuel pulse damper cannot be mounted directly to the fuel rail.

The Radium FPD-R mounts in the OEM location on a stainless steel bracket and has a vacuum reference for high-boost engines.
