[PN: 20-164] Radium Fuel Pump Hanger, Mitsubishi EVO X

The new Radium Engineering fuel pump hanger for the Mitsubishi EVO X has been redesigned for improved fuel collection and easier installation. It completely replaces the factory in-tank fuel pump module and allows 1 or 2 aftermarket fuel pumps to be used. The OEM level sender, fuel temperature, and fuel tank pressure sensor are retained in order to maintain factory functionality. Please note that product may differ slightly from what is shown in photos and videos.

PLUMBING

For direct connection to the OEM fuel lines, adapter fittings are included with all configurations. The fuel hanger can also be used with the included 8AN and 6AN adapter fittings for installing aftermarket AN style hoses.

FUEL STARVATION

The kit includes a 1-piece anodized aluminum collector box that makes installation a breeze and keeps fuel trapped around the pump inlet(s). As shown below, there is a 355 LPH 1-way fill valve incorporated in the bottom of the collector that allows fuel in, but not out. The collector box is constantly replenished with fuel returning from the pressure regulator.

VENTURI JET PUMP

• The OEM venturi jet pump in the return line creates a restriction with the stock EVO X fuel pump module.
• Radium Engineering has redesigned the siphon system to eliminate this restriction but still effectively scavenges fuel. This means higher flowing pumps can safely be used without fuel pressure issues.
• Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps.
• 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. NOTE: The fuel filter provided with the 20-0946-0X feed kits (listed below) include an integrated check valve.

The feed kit provides a high-flow 8AN PTFE hose and fuel filter for a restriction-free fuel feed line (kit contents shown below). The fuel filter incorporates an integrated check valve. The engine must be equipped with a fuel rail that can accept an 8AN feed hose, such as this one. The included fuel filter will be assembled with a 10 micron stainless fuel filter element. The kit includes a specially designed mounting bracket for the fuel filter which uses OEM mounting holes, so no drilling or chassis modifications are required for installation. 

The fuel hanger return kit provides all of the necessary hose, fittings, and hardware to convert the OEM Evo X fuel feed line to be used as the return line. Exact contents of this kit are shown in the photo below. This is a method to replace the restrictive 1/4' (6.5mm) OEM return hose, critical for proper regulator function. In the engine bay, the -6AN PTFE return hose will attach directly to a Radium Direct Mount Regulator when mounted in the top port of a Radium fuel rail. The two SAE quick connect fittings allow each end of the OEM feed line to be connected in an easy, leak-free manner to the rest of the kit.

Many vehicles outside of North America did not come standard with the OEM fuel tank pressure sensor. This part is necessary to plug the port hole on the fuel hat top. To secure, use the 2 button head bolts provided with the fuel pump hanger.
