Radium Fuel Rail Plumbing Kit | Nissan VQ35DE (20-0468)

The VQ35DE rails have eight ports and a factory hard line waiting; this kit wires them together.

The Radium Engineering Fuel Rail Plumbing Kit for the Nissan VQ35DE completes the 20-0458 rail installation on the factory fuel system: an SAE adapter connects the OEM hard line under the vehicle, PTFE hoses route the feed to the rear rail ports, 6AN adapters and plugs dress every port correctly, and the 20-0460 adapter reuses the OEM pulse damper so factory pressure smoothing carries over. Engine-specific by design, this DE version routes to the rear ports, while HR and VHR engines use the separate 20-0469 front-port kit. Fuel rails sold separately.

What You'll Feel

• A plug and play rail install on the factory feed system, no fitting research required
• OEM pulse damping retained through the included 20-0460 adapter
• All-fuel confidence from PTFE hoses, E85 included
• Every unused rail port properly plugged and reserved for future accessories

The Details

The engine-specific split exists because Nissan moved the plumbing between generations, with the DE feeding from the rear and the HR/VHR from the front, so kit selection follows the engine code stamped on the block rather than the chassis badge. One DE-specific rail note carries over from the rail listing: the OEM intake manifold mounting bosses require two 14-0150 plugs occupying one center port per rail, sold separately, a quirk unique to the DE. Radium's install documentation covers the SAE quick connect release procedure at the hard line, and the usual disciplines apply, with ORB O-rings lubricated and the OEM damper transferring to its new adapter home. Together with the rails, the result is a factory-serviceable fuel system with aftermarket headroom.
