Overview

The AMS Evo X / Ralliart Fuel Pressure Regulator Kit (part number AMS.04.07.0001-1) is for Lancer Evolution X and Lancer Ralliart owners running an upgraded fuel pump, larger injectors or both. It lets you set base fuel pressure where your tune needs it: lower it if the car is running rich, or raise it if your injectors are running out and the car is lean.

The kit is built around a Fuelab 1:1 black fuel pressure regulator and includes a vibration-resistant, liquid-filled 0-100 psi gauge so you can monitor fuel pressure at a glance. A return line mates to the factory steel return line, and the feed line and fittings bolt to any stock or stock-replacement fuel rail.

Everything mounts on the included plate with -6 AN fittings, and installation needs no cutting or modification, so the kit can be removed later if you ever return the car to stock. Detailed installation instructions are available from AMS.
