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.

NOTES

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

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.

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 valves somewhere in the fuel system. NOTE: The fuel filter provided with the 20-0946-0X feed kits include an integrated check valve.

FUEL FILTRATION 

• 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.
• 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 plumbing kits listed below include a post-pump filter.

ELECTRICAL 

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