Radium: 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.
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.
