Fuel Rail Radium Engineering for Toyota UZ VVT-i

PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB.

• 8AN ORB Adapter Fittings
• 8AN ORB Direct Mount Regulators
• 8AN ORB Fuel Pulse Dampers
• Fuel Pressure Gauge Adapters

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

OVERVIEW

Manufactured with 0.7" large internal bores, the Radium Engineering fuel rails can support all necessary engine power requirements. The modular billet aluminum mounting feet make these fuel rails compatible with the early and late VVT-i intake manifolds.

FUEL INJECTOR COMPATIBILITY

OEM TOYOTA INJECTORS 

The Radium Engineering fuel rail features 11mm injector bores making it compatible with ALL factory Toyota UZ fuel injectors. No modifications are needed. 

AFTERMARKET INJECTORS ON 2UZ-FE ENGINES (WITHOUT AIR-ASSIST)

For engines that do NOT use Toyota air assist equipment, use your preferred injector manufacturer's suggestion for OEM equivalent fuel injectors. DO NOT USE THE INJECTORS LISTED BELOW WHICH ARE FOR AIR-ASSIST ENGINES ONLY.

AFTERMARKET INJECTORS ON 3UZ-FE AND 1UZ-GE VVT-I ENGINES WITH AIR-ASSIST

These engines use Toyota air-assist emissions equipment. These engines use a unique OEM fuel injector that is not replicated in the aftermarket. Air-assist intake manifolds require the provided injector seats in order to use universal aftermarket fuel injectors.

When the included injector seats are installed into these air-assist intake manifolds, an aftermarket injector that is 60mm long with 11mm upper O-ring and 14mm lower O-ring must be used. The following universal injectors have been verified to be compatible, however there are others on the market that will work that are not listed here.

• Injector Dynamics ID1050-XDS-60-11-14
  
• Injector Dynamics ID1300-XDS-60-11-14
  
• Injector Dynamics ID1700-XDS-60-11-14
  
• Injector Dynamics ID2600-XDS-60-11-14

FUEL RAIL PORTS

Each fuel rail has three 8AN ORB (3/4"-16) ports or 6 total.

Adapter fittings and fuel hose will need to be purchased separately.

FEATURES

• Anodized surface finish for wear and corrosion resistance
• Lighweight aluminum construction
