radium ENGINEERING Fuel Hanger Tank, WALBRO & AEM (Mitsubishi Evolution X)

The 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.

FEATURES
-8AN ORB Female Pump-Out Port
-6AN ORB Female Return Port
-Collector Box with 1-Way Fill Valve
-Venturi Jet Pump Siphon
-Single Merged Fuel Pump Outlet
-High Current Electrical Connections
-Black Anodized Adapter Fittings
-Fuel Level and Temp Sensor Mount
-Twin Fuel Pump Compatibility
-Stainless Hardware and Clamps
-Alternative Fuel Compatibility

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. Radium Engineering recommends upgrading the feed and return lines when using multiple pumps.

NOTES: There is an OEM pressure sensor (Mitsubishi 8651A025) found on the top hat to meet North American emission standards. For international vehicles that did not come with this standard, 20-0421 EVO X FUEL TANK PRESSURE PLUG is required.

PREVENTING 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). 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.

NOTES ABOUT THE VENTURI JET PUMP
1. The OEM venturi jet pump in the return line creates a restriction with the stock EVO X fuel pump module.
2. 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.
3. Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps.
4. If it is important for fuel pressure to hold steady after the engine is shut down, install a CHECK VALVE somewhere in the fuel system.

NOTES ABOUT PUMP CONFIGURATION
There will be enough components included with this option to use 1 or 2 fuel pumps. Depending on the setup, some parts will simply not be used. A pliable fuel pump filter sock must be used for proper fitment. This system is compatible with the following fuel pumps:

20-0642-00
Walbro F90000267
Walbro F90000274
Walbro F90000285

20-0640-00
Walbro GSS342 255lph
AEM 50-1220

20-0644-00
Deatschwerks DW400

NOTES ABOUT FILTRATION
1. 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.
2. This kit eliminates the OEM "post" fuel pump filter. A low-micron aftermarket fuel filter should be installed downstream to protect the injectors from debris.
3. The optional fuel plumbing kits include a post-pump filter.

NOTES ABOUT WIRING
1. Single fuel pump installations can re-use the OEM fuel pump controller wiring.
2. Radium recommends upgrading the wiring to ensure the pumps are operating at their full potential.
