Product details

Description

The VK56DE holds 2,000hp on a stock block. Its factory fuel rails were not designed with that in mind.

The Radium Engineering fuel rails for the Nissan VK56DE replace the factory rails with CNC machined billet aluminum carrying AN ORB ports. The VK56 is found in the Titan, Armada, and Patrol and has become a popular swap engine precisely because it supports massive forced induction builds up to 2,000hp on stock internals, which is exactly when factory fuel delivery becomes the limit.

Choose Your Part

  • Fuel rails (20-1056)
  • Fuel rail plumbing kit (20-1056-PK): bolt-on replacement for the OEM rail system

What You'll Feel

  • Fuel flow that keeps up with a boosted VK56 rather than capping it
  • A bolt-on swap when paired with the plumbing kit, with nothing else required
  • Factory hoses and pulse dampers retained rather than replaced
  • PTFE crossover hose that handles E85 without permeation

Features

  • CNC machined billet aluminum fuel rails
  • AN ORB threaded ports with plugs supplied for unused ports
  • 8AN crossover manufactured from PTFE hose, compatible with all fuel types including E85
  • Plumbing kit reuses all OEM fuel hoses and pulse dampers

The Details

The plumbing kit is what makes this a straight swap. Radium's framing is that 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 PTFE, and plugs come with it for every unused port.

Buying the rails alone suits custom builds sourcing their own fittings and hose. For anyone adapting an OEM fuel pressure regulator to these rails, the 20-1459 VK56DE FPD adapter covers that connection. Leave clearance around any port destined to carry a regulator, gauge, or damper.

Kit Includes

  • 20-1056: fuel rails with mounting hardware
  • 20-1056-PK: 8AN PTFE crossover hose, adapter fittings, and ORB plugs for unused ports
  • NOT included: fuel injectors

Applications

  • Nissan VK56DE engines, including the Titan, Armada, and Patrol
  • VK56DE engine swaps

Important Notes

  • The plumbing kit is designed for use with the 20-1056 rails
  • Confirm your engine is VK56DE rather than the later VK56VD before ordering
