Fuel Pump Hanger Mitsubishi EVO 7-8-9 Walbro F90000267/274/285 Radium Engineering

The Radium Engineering fuel pump hanger allows the use of 1 or 2 aftermarket pumps in the stock Mitsubishi Evo 7-8-9 fuel tank.

The machined assembly drops-in the factory fuel tank replacing the OEM hold-down flange. A single 8AN male pump feed port and 6AN male return port simplify aftermarket -AN hose plumbing. However the preassembled adapter fittings are compatible with the OEM fuel lines. This system is ONLY compatible with the following pumps:

20-0345-00
Walbro F90000267
Walbro F90000274
Walbro F90000285

One major issue with the OEM EVO 7-8-9 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 integrated pressure-relief valve to minimize back pressure.

All returning fuel from the pressure regulator and crossover hose exit the jet pump keeping the OEM gas tank baffle full for starvation protection.

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

Pump Configuration Selection

- 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 (20-0345-10 shown below).

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