Description

Manufactured with 0.7" large internal bores, the Radium Engineering fuel rails can support all necessary engine power requirements.

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.

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.

 

FUEL INJECTORS
FOR ENGINES WITHOUT AIR ASSIST
The Radium Engineering fuel rail features 11mm injector bores making it compatible with ALL factory Toyota UZ fuel injectors. No modifications are needed. The machined injector ports are compatible with 11mm upper injector O-rings. The fuel rails are compatible with OEM fuel injectors (or OEM equivalent). This means that the injectors being installed must match the OEM height and o-ring dimensions. Radium can not make injector recommendations other than stating "OEM equivalent".

DO NOT USE THE INJECTORS LISTED BELOW WHICH ARE FOR AIR-ASSIST ENGINES ONLY.

FOR ENGINES WITH AIR ASSIST
These engines use Toyota air-assist emissions equipment, and use a unique OEM fuel injector that is not replicated in the aftermarket. With this rail the OEM air-assist fuel injector can be reused, or universal aftermarket fuel injectors can be used with the provided air-assist injector seats.

When the provided Radium 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. Consult your injector supplier for more information and recommendations.
