Radium - Fuel Rails for Nissan VK56DE

Manufactured with large internal bores, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. There are provisions for the retaining clips for proper indexing of all OEM fuel injectors. 

Each fuel fail has five 8AN ORB ports (ten total). 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.

The fuel rail plumbing kit allows for an OEM bolt-on affair. Nothing else is required to fully replace the OEM fuel rail system. All OEM fuel hoses and pulse dampers are reused. The 8AN crossover is manufactured from high quality PTFE hose compatible will all fuel types including E85. Plugs are included for all unused ports.
