Radium Engineering Toyota 1JZ-GTE (VVT-I) Fuel Rail

Installation Instructions

The fuel rail ports are tapped for 8AN ORB.

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.

Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from 6063 aluminum, black anodized, and laser etched for a high quality surface finish. For flexibility, the fuel rail features three 8AN ORB ports and is compatible with all fuel types including popular alcohol mixtures such as E85.

The Radium fuel rail is compatible with the OEM 1JZ-GTE VVT-i top-feed fuel injectors and any aftermarket injectors that fit the OEM fuel rail. Injector bores are 11mm.

Lightweight billet aluminum mounting feet are provided for strength. To prevent corrosion, stainless steel hardware is included.

As shown below, the fuel rail re-uses the factory mounting bolts and plastic insulating spacers. Make sure these are present before beginning installation.

Unlike the previous 20-0268 fuel rail, this 20-0768 fuel rail is compatible with all 1JZ-GTE VVT-i engines including those using the ETCS-i throttle body (shown below).

To reuse the OEM fuel pressure regulator, select the 14-0285 8AN ORB to M12x1.25mm Fitting (shown below).
