A low-micron aftermarket fuel filter should be installed downstream to protect the injectors from debris. This kit eliminates the OEM "post" fuel pump filter. If a configuration with fuel pumps included is selected, the kit will come preassembled and 65 micron sock filters will be installed on the fuel pump inlets. When the unit is purchased with one pump included, additional parts will be needed to install a second pump. The unit will arrive ready to be dropped in with only minor assembly required. A pliable fuel pump filter sock like this HERE must be used for proper fitment. Depending on the setup, some parts will simply not be used. There will be enough components included with this option to use 1 or 2 fuel pumps. NOTE: If it is important for fuel pressure to hold steady after the engine is shut down, install one of these CHECK VALVES somewhere in the fuel system. This means higher flowing pumps can safely be used without issue from the return system. Radium Engineering has redesigned the siphon system to eliminate restriction but still effectively scavenge fuel. Many installers will simply drill out the OEM venturi jet pump to reduce the restriction, but this compromises how effectively the venturi functions. When using aftermarket high-flow pumps, the restriction in the fuel return creates unwanted backpressure resulting in unmanageable fuel pressure. It performs the important function of transferring fuel from the other side of the fuel tank to the pump module. One major issue with the stock EVO X fuel pump module is the restrictive venturi jet pump in the return line. The collector box also stay full from the fuel returning from the pressure regulator. As shown below, there is a 1-way fill valve incorporated in the bottom of the collector that allows fuel in, but not out. The kit includes a 1-piece anodized aluminum collector box that makes installation a breeze and keeps fuel trapped around the fuel pumps. Radium Engineering recommends upgrading the feed and return lines when using multiple pumps. The fuel hanger can also be used with the included 8AN and 6AN adapter fittings, shown below, for installing aftermarket -AN style hoses. Compatible with alternative fuels such as E85įor direct connection to the OEM fuel lines, adapter fittings (shown installed below) are included with all configurations. Radium Engineering recommends reviewing the installation instructions (posted in the link above) before purchase.įor a complete and comprehensive fuel delivery system for the EVO X, CLICK HERE. The OEM level sender, fuel temperature, and fuel tank pressure sensors are retained in order to maintain factory functionality. It completely replaces the factory in-tank fuel pump module and allows 1 or 2 aftermarket fuel pumps to be used. The new Radium Engineering fuel pump hanger for the Mitsubishi Evo X has been redesigned for improved fuel collection and easier installation. This product is compatible with the following:
