PORTS AND 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.
Manufactured with 0.69″ large internal bores, the Radium Engineering fuel rails can support all necessary engine power requirements. CNC machined aluminum mounting tabs are included for a factory fit and to maintain the original fuel rail height so both OEM or aftermarket equivalent injectors can work.
