Radium Fuel Rail, Honda D-Series

The Radium Engineering 20-1070 Fuel Rail is designed for: Honda D-Series engines.

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

This fuel rail has 4 ports that are tapped with 7/8”-14 threads to accept 8AN ORB male fittings.

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. Dimensional drawings are available from Coore on request to verify clearance.
