PRODUCT DESCRIPTION
This kit is not compatible with the Radium fuel delivery system for the Supra MKIV.
This Radium Engineering kit completely replaces the OEM fuel pulse damper (see below) on the JZA80 Supra 2JZ-GTE engine. It also replaces the fuel feed line from the filter to the fuel rail, eliminating four restrictive banjo connections. Since this kit uses -6AN sized hoses, it can be used with an aftermarket fuel rail or the factory fuel rail (adapters are included for both options). This is an excellent option when it is not possible to mount an aftermarket fuel pulse damper directly to the fuel rail.
Anodized aluminum adapters are included to allow for use of the OEM fuel rail or an aftermarket 8AN ORB fuel rail. The Radium Fuel Pulse Damper (FPD-R) mounts in the original location via a stainless steel bracket. The FPD-R features a vacuum reference for high boost engines.
NOTE: The larger FPD-XR is not compatible, as it would interfere with the starter motor.
