Radium EVO X Fuel Hanger, Walbro F90000267/274 E85

The Radium Engineering fuel pump hanger allows the use of 1 or 2 aftermarket pumps in the stock Mitsubishi Evo X fuel tank. The machined assembly drops-in the factory fuel tank using the OEM hold-down flange. A single 8AN male pump feed port and 6AN male return port simplify aftermarket -AN hose plumbing. Electrical hardware is included for the fuel pump power, OEM level sender, and OEM temperature sensor.

The custom designed stainless electrical studs easily handles the high current demand that compact bulkhead connectors lack. These serviceable connections are properly sealed and impervious to all standard and exotic fuels. The low profile design keeps all wiring tucked nicely underneath the OEM cover plate. Nylon acorn nuts are provided to prevent any accidental short circuits. Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE.

One major issues with the OEM EVO X fuel pump hanger is the restrictive return port and venturi jet pump. 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. The Radium fuel pump hanger includes a venturi jet pump with a new pressure-relief valve to minimize back pressure. 

The kit also includes a 2-piece anodized aluminum collector box that sits at the bottom of the OEM fuel tank. This container is NOT a total solution to fuel starvation, but does improve the fuel supply around the pump(s) inlet. There are two 1" ball check valves incorporated on the front and rear of the box that serves as trap doors keeping the pump(s) supplied with fuel during aggressive driving. Furthermore, all returning fuel from the pressure regulator return and the crossover hose enter the collector box keeping it full. The collector box also permits a mounting solution for the OEM fuel level and fuel temperature sensors. Also included are 2 mating connectors for the sensors making the kit easily serviceable.

Single pump applications can reuse the OEM fuel pump controller wiring, but it is recommended to upgrade the OEM wiring as high flow fuel pumps draw additional current requiring larger gauge wire. Fuel pump wiring kits can be purchased . Select qty1 for single pump applications and qty2 for dual pump applications.

Pump Configuration Selection 

If supplying your own pumps, select the option "Pumps Not Included" from the menu. 
Notes:
1. 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.
2. A pliable fuel pump filter sock like this  must be used for proper fitment.

Next, select the type of pumps that will be used so the appropriate internal wiring connectors will be included in the kit. If pumps are needed, the kit will come preassembled and 65 micron sock filters will be installed on all fuel pumps. 

This kit eliminates the OEM hanger's "post" fuel pump filter. A low micron  should be installed downstream to protect the injectors from debris. NOTE: the optional fuel feed kits listed below include a post pump filter.
