THIS KIT IS NOT COMPATIBLE WITH THE RADIUM FUEL DELIVERY SYSTEM FOR THE MKIV SUPRA.  This Radium Engineering kit completely replaces the OEM fuel pulse damper (below) found on the JZA80 Supra 2JZ-GTE engine. It also replaces the fuel feed line from the filter to the fuel rail eliminating 4 restrictive banjo fittings. Because this kit uses -6AN size hoses, it can be used with an aftermarket fuel rail, or with the factory fuel rail (adapters are included for both options). This is a great option when an aftermarket fuel pulse damper cannot be mounted directly to the fuel rail. Anodized aluminum adapter fittings are included to permit the use of the OEM fuel rail or an aftermarket 8AN ORB fuel rail. The Radium fuel pulse damper (FPD-R) mounts to the OEM location using a stainless steel bracket. The FPD-R has a vacuum reference for high boosted engines. NOTE: The larger FPD-XR is not compatible as it would interfere with the starter.
