The Radium fuel pump hanger includes Radium's own proprietary venturi jet pump with interchangeable orifices to minimize back pressure.
When using aftermarket high-flow fuel pumps, the OEM jet pump becomes too restrictive creating unwanted backpressure in the regulator return line causing excessive fuel rail pressure. One major issues with the OEM EVO X fuel pump hanger is the restrictive return port and venturi jet pump. Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE. Nylon acorn nuts are provided to prevent any accidental short circuits. The low profile design keeps all wiring tucked nicely underneath the OEM cover plate. These serviceable connections are properly sealed and impervious to all standard and exotic fuels. The custom designed stainless electrical studs easily handles the high current demand that compact bulkhead connectors lack. Electrical hardware is included for the fuel pump power, OEM level sender, and OEM temperature sensor. A single 8AN male pump feed port and 6AN male return port simplify aftermarket -AN hose plumbing. The machined assembly drops-in the factory fuel tank using the OEM hold-down flange. NOTE: the optional fuel hanger plumbing kits listed below include this necessary post pump filter.The Radium Engineering fuel pump hanger allows the use of 1 or 2 aftermarket pumps in the stock Mitsubishi Evo X fuel tank. A low micron aftermarket fuel filter should be installed downstream to protect the injectors from debris. NOTE: This kit eliminates the OEM hanger's "post" fuel pump filter. Depending on the setup, some parts will simply not be used (20-0345-10 shown below). There will be enough components included with this option to use 1 or 2 fuel pumps.
