Radium Engineering Toyota 3UZ-FE/1UZ-FE VVT-I Fuel Rails for 1998-2010 Lexus GS400 GS430 SC430 LS400 LS430

Radium Engineering fuel rails deliver precise even fuel distribution to all cylinders on Toyota 3UZ-FE and 1UZ-FE VVT-I engines found in Lexus models. They install directly on 1998-2000 GS400, 2001-2005 GS430, 2002-2010 SC430, 1998-2000 LS400, and 2004-2006 LS430 without modifications. High-flow passages and integrated ports handle boosted or high horsepower builds while maintaining factory fuel rail height.

Key Features

  • CNC Machined Aluminum: Built from 6061-T6 aluminum with black anodized finish for strength, light weight, and resistance to fuel corrosion and heat.
  • 8AN ORB Ports: Three ports per rail enable simple connections for fuel pressure regulators, sensors, and return lines in custom fuel systems.
  • Direct Bolt-On Fit: Aligns perfectly with OEM mounting points, no drilling or alterations required for seamless integration.
  • Injector Compatibility: Works with OEM Toyota injectors and aftermarket options using supplied air-assist delete seats for reliable sealing.

Fuel Delivery

Fuel Delivery

A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...

Fuel Rails

Fuel Rails

Fuel rails are the high-pressure manifolds that distribute fuel from the supply line to each injector on the engine, and upgrading from factory rails is one of the most impactful fuel system improvements for high-output EFI builds. Factory plastic or cast aluminum rails are designed to adequate specifications for stock fuel demand but often lack the integrated AN fittings, pressure sensor ports, and internal volume needed for modified engines running elevated fuel pressure or higher-flow injectors. Billet aluminum fuel rails machined from 6061 aluminum provide the rigidity and smooth bore finish that maintains consistent pressure distribution across all injector feeds, preventing the pressure standing waves that cause cylinder-to-cylinder fueling variation at high RPM. Whether you are building a show engine with a clean plumbing aesthetic or a race engine demanding maximum fuel flow reliability, the right fuel rails are the backbone of a well-designed EFI system.
