The Radium Engineering VQ fuel rails are a high-flow upgrade for Nissan and Infiniti VQ35DE, VQ35HR and VQ37VHR V6 engines. Machined from 6061 aluminium and black anodised, each rail features a large internal bore and is compatible with all common fuel types including E85.

Each rail has four 8AN ORB ports (two on the ends and two on the bottom) and 14mm injector bores. The extra ports accept accessories such as a pressure transducer or fuel pulse dampers, and the rails can be plumbed in parallel, in series or as a return-style system. The rails mount with stainless steel brackets and hardware, and the OEM injector clips can be reused on the VQ35DE and VQ35HR.

Important Notes

• This listing is for the fuel rails only – plumbing kits, fittings, regulators and pulse dampers are sold separately
• This is an upgrade rail – OEM or OEM-equivalent injectors must be used. Radium does not make injector recommendations
• VQ35DE only: two Radium 14-0150 8AN ORB plugs must be fitted to the centre ports of one rail due to the OEM intake manifold bosses
• The VQ37VHR is not compatible with any Radium aftermarket fuel pulse damper – only the OEM dampers can be used
• VQ rail fitment has very tight clearances, so pulse dampers can only be fitted in certain positions – refer to Radium's fitment chart and dimensional drawings
• Top feed conversion rails for side-feed or air-assist applications are a separate product
• Installation instructions are available in the Instructions tab
