RADIUM Engineering 20-1389 Fuel Pulse Damper Kit for MK4 Supra 2JZ-GTE

This RADIUM Engineering kit completely replaces the OEM fuel pulse damper 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 that limit flow in the factory setup.

The opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors.

Key Features:

• Uses 6AN size hoses and can be used with an aftermarket fuel rail or with the factory fuel rail (adapters included for both options)
• OEM rubber hoses are replaced with E85 safe PTFE fuel lines
• 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
• No permanent modifications required
• Stainless steel hardware included

This is a great option when an aftermarket fuel pulse damper cannot be mounted directly to the fuel rail. RADIUM Engineering FPDs use a vacuum/boost reference port which allows for proper fuel pulse damper performance even at elevated fuel pressures. This becomes essential for boosted systems that use a 1:1 rising rate fuel pressure regulator.
