Radium Engineering Fuel Pulse Damper Kit for Toyota Supra JZA80 2JZ-GTE

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

Application: Toyota Supra MK4 (JZA80) – 2JZ-GTE
Part Type: Fuel pulse damper kit (OEM damper and feed line replacement)
Part Number: 20-1389

The Radium 20-1389 Fuel Pulse Damper Kit completely replaces the OEM fuel pulse damper on the JZA80 Supra 2JZ-GTE, and 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, with anodised aluminium adapter fittings for both included. The Radium FPD-R mounts in the OEM location on a stainless steel bracket and has a vacuum reference for high-boost engines – a great option when an aftermarket damper can't be mounted directly to the fuel rail. It can also be used as a feed line kit to plumb a Radium fuel rail into the OEM fuel lines.

Key Features

• OEM Damper Replacement: Radium FPD-R with vacuum reference replaces the OEM fuel pulse damper
• Eliminates 4 Banjo Fittings: New 6AN feed line from the filter to the rail
• OEM or Aftermarket Rail: Adapters included for the OEM rail and 8AN ORB aftermarket rails
• OEM Location: Stainless steel bracket reuses the factory threaded bosses
• No Permanent Modifications: Works with the OEM fuel filter

What's Included

• Radium FPD-R fuel pulse damper
• Stainless steel damper mounting bracket
• Anodised aluminium adapter fittings (OEM rail and 8AN ORB rail)
• 6AN PTFE fuel hose
• EFI rubber hose
• Stainless steel hardware

Important Notes

• The larger FPD-XR damper is not compatible with this kit – it interferes with the starter
• Per Radium's instructions: if total fuel pressure may exceed 70psi, connect the damper's vacuum port to the intake manifold; otherwise plug it with the #10-32 screw
• The metric adapter is for the OEM side feed rail; the 8AN ORB adapter suits aftermarket rails with a 3/4in-16 (8AN ORB) rear port
• Installation instructions are available in the Instructions tab
