Aftermarket intake manifold compatibility has not been tested or verified. These fuel rails follow the factory mounting and position.

Manufactured with a large internal bore, the fuel rail can support all engine power requirements. They are CNC machined from 6061 aluminum, anodized, and laser etched for a high-quality surface finish. Like the factory fuel rails, the injector bores are 11mm ID, so factory or any equivalent aftermarket injectors can be used.

FUEL INJECTOR COMPATIBILITY

This fuel rail is compatible with factory or factory-equivalent fuel injectors. If upgrading fuel injectors, they must maintain factory height and O-ring dimensions for proper fitment. Consult your aftermarket injector supplier for more details. Radium Engineering cannot specify additional dimensions for injectors, only states "OEM equivalent."

PORTS & CONNECTIONS

This fuel rail has 4 threaded ports with 7/8"-14 to accept 8AN ORB male connections.

8AN ORB Adapters.

8AN ORB Direct Mount Regulators.

8AN ORB Fuel Pulse Dampers.

Adapters for Fuel Pressure Gauges.

Appropriate connections must be selected based on the specific application. Sufficient clearance around the fuel rail ports is required for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, you can use the dimensional blueprints on the product pages as a reference guide.
