The Radium Engineering Fuel Rail Plumbing Kit includes all of the individual pieces needed for a bolt-on solution for VQ35DE models when using the Radium Engineering VQ Fuel Rails.

When used with the base fuel rail kit (PN: 20-0458) this permits a bolt-on, plug and play affair for the VQ35DE engines. An SAE adapter connects to the OEM hard line underneath the vehicle. PTFE hoses route fuel to the rear fuel rail ports. 8AN ORB plugs and 6AN adapter fittings are included for all fuel rail ports. Additionally, adapter (PN: 20-0460) is included to allow the OEM fuel pulse damper to be reused.

Install Note: Because of the OEM intake manifold mounting bosses, two Radium 14-0150 8AN ORB plugs must be used in 1 of each of the center ports for VQ35DE engines ONLY. This is optional below and ONLY applies to DE applications.
