Using this fuel rail kit is straightforward. First, check your vehicle's compatibility - it fits specific Nissan 350z, 370z and Infiniti G35, G37 models and certain VQ engines. When installing, use the stainless - steel brackets and hardware provided to mount the fuel rails. You can reuse the OEM injector clips if you have a VQ35HR or VQ35DE engine. Since there are multiple ports on each rail, you have the freedom to choose different plumbing configurations according to your needs. Remember, no fittings are included in the kit. For VQ35DE engines, make sure to use two Radium 14 - 0150 8AN ORB plugs in one of each center ports because of the OEM intake manifold mounting bosses. For maintenance, keep the fuel rails clean. Since they are anodized black and made of 6061 aluminum, they are resistant to corrosion from popular fuels like E85. Periodically check the ports and connections for any signs of wear or leakage.
