Description

NOTE: Many vehicles outside of North America did not come standard with the OEM fuel tank pressure sensor. If your hanger does not have this, please add the Radium # 20-0421 plug to cart.

 

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 sensors 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 fittings
  • Fuel Level and Temp Sensor Mount
  • Compatible with Twin Pumps
  • Fluorosilicone Duckbill Return Valve
  • Stainless Steel Hardware and Clamps
  • Compatible with alternative fuels such as E85

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, shown below, for installing aftermarket -AN style hoses. Radium Engineering recommends upgrading the feed and return lines when using multiple pumps.

 

PREVENTING FUEL STARVATION

The kit includes a 1-piece anodized aluminum collector box that makes installation a breeze and keeps fuel trapped around the fuel pumps. 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 collector box also stay full from the 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 one check valve somewhere in the fuel system.

NOTE: The fuel filter provided with the 20-0946-0X feed kits (listed below) include an integrated check valve.

 

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. This system is compatible with the following fuel pumps:

  • Walbro GSS342 255lph
  • AEM 50-1220 340lph

 

NOTES ABOUT FILTRATION

  • The kit will include 65 micron sock filters to be installed on the fuel pump inlets.
  • 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.
  • The optional fuel feed kits listed below include a post-pump filter.

 

OPTIONAL ADD-ONS (Sold Separately):

20-0246-XX FUEL HANGER FEED, EVO X

  • The feed kit provides a high-flow 8AN PTFE hose and fuel filter for a restriction-free fuel feed line. The engine must be equipped with a fuel rail that can accept an 8AN feed hose, such as this one. Depending on the kit selected (-01,-03,-05), the fuel filter will be assembled with one of three different elements.

20-0249 FUEL HANGER RETURN, EVO X

  • 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 (Part number 20-0623-0X) 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.
