New from Radium Engineering – a fuel pump hanger for the Mitsubishi Evo X. This product allows  the use of one or two aftermarket pumps in the stock fuel tank, and works with the OEM fuel level and temperature sensor.

Official Release:

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. An electrical bulkhead connector is included for the fuel pump power, OEM level sender, and OEM temperature sensor.

One of the main issues with the stock 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 Radium’s own proprietary venturi jet pump with interchangeable orifices 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 online. Select qty1 for single pump applications and qty2 for dual pump applications.
