So you've made the decision to go with a forced induction system....comgratulations! The fuel system is one area that most of the forced induction kits on the market do not adequately address. Altered has stepped up to the plate with their awesome billet fuel system for the 350Z. They offer 3 different kits to suit your particular needs. The first kit is a more "Tuner" oriented setup, as it provides the rails themselves, thus allowing the user to select their own regulator, and pump upgrade. Their next setup steps you up into a more "complete" system, featuring the billet rails, an external fuel pressure regulator, full -AN fittings. For those looking for a complete solution that will easily handle 500 + whp, we also offer the full system kit. This includes everything mentioned above, but also includes an upgraded, high flow fuel pump. Detailed instructions are included with all kits. Usually ships in 1-5 days. Fuel rails only fit 2003-2006 Z/G models - does not fit 2007+ cars. See listing below for the return fuel kit for the 2007-2008 cars with HR engine.
