Radium Engineering Fuel Rails - Nissan / Infiniti VK56DE 5.6L V8
Radium Engineering's VK56DE fuel rails replace the factory rails on the Nissan / Infiniti 5.6L V8 with large-bore billet units that support any realistic power target. They are CNC machined from solid 6061 aluminium, black anodised and laser etched, and keep the OEM 14mm injector bore with retaining-clip provisions so factory injectors index correctly (SKU 20-1056).
Each rail has five 8AN ORB ports (ten in total) for feed, return, regulators, gauges and dampers. The matching 20-1056-PK plumbing kit is available separately for a complete bolt-on install.
Note: Port fittings are sold separately and must be chosen to suit your application. Allow clearance around the ports for larger accessories such as regulators, gauges and pulse dampers. Installation by a professional is recommended.
