Radium Fuel Rail Plumbing Kit | Nissan VQ35HR & VQ37VHR (20-0469)

Radium rails on an HR or VHR deserve plumbing engineered to the same standard.

The Radium Engineering Fuel Rail Plumbing Kit for the Nissan VQ35HR and VQ37VHR completes the Radium rail installation on the late VQ platforms: the hoses, fittings, and hardware connecting the rails to the vehicle's fuel supply in the configuration the 350Z HR, 370Z, and G35/G37 sedans and coupes run. Rails sold separately.

What You'll Feel

• The rail install finished with matched, engineered plumbing instead of pieced-together fittings
• Correct interfaces at the vehicle's fuel supply and both rails
• E85-ready materials through the whole path

Features

• Plumbing kit for Radium VQ35HR/VQ37VHR fuel rails (sold separately)
• Hoses, fittings, and hardware for the platform's supply configuration
• All fuel types including E85

The Details

The HR-generation VQ revised the fuel architecture from the earlier DE cars, which is why this kit exists separately from Radium's VQ35DE plumbing: interfaces, routing, and damper provisions all differ across the generational split, and matching the kit to the engine code matters more than matching the badge. The 20-0459 FPD adapter and FPD-R damper slot naturally into the same install for builds adding pulse damping, and flex fuel sensors splice per the standard return-path pattern. Standard discipline throughout: ORB O-rings lubricated, flares dry, leak check before first start.
