Fitment with aftermarket intake manifolds is not tested and cannot be verified. These fuel rails follow OEM mounting and positioning.

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.

20-1070 Fuel Rail, Honda D-Series

FUEL INJECTOR COMPATIBILITY

This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, they must maintain the OEM height and O-ring dimensions for proper fitment. Consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating "OEM equivalent".

PORTS AND FITTINGS

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

• 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.
