Radium Introduces 2003-07 Lancer Evo In-Tank Fuel Pump Hanger Kit

New from Radium – the In-Tank Fuel Pump Hanger for 2003-07 Mitsubishi Lancer Evolution 8-9. This hanger increases pump flow capacity to feed high horsepower engines. See more details below.

Official Release:

Making more horsepower requires more fuel to be sent to the engine. The Radium fuel pump hanger increases the pump flow capability while offering other advantages as well.

The hanger drops right into the OEM fuel tank and can be configured to use one or two Walbro F90000267/274 (aka Walbro 450 E85) high-flow pumps, able to supply up to 1,400HP worth of fuel. THIS HANGER IS ONLY COMPATIBLE WITH WALBRO 450 E85 PUMPS.

As with other Radium in-tank hangers, this one includes a venturi jet pump that has been specially designed to operate with high flow pumps without causing high back pressure in the return line. The venturi jet pump uses the fuel returning from the regulator to create suction which draws fuel from the opposite site of the saddle fuel tank. The return fuel and the suction fuel is then deposited into the OEM collector box where the pump inlets are located. This system ensures there is always ample fuel around the fuel pump inlets.

The Radium fuel pump hanger packages nicely inside the OEM in-tank collector box. The OEM collector box uses a wrap-around tube to allow fuel in, but keep it trapped during aggressive driving.

The CNC machined aluminum top plate is designed to mimic the plumbing connections found on the OEM fuel pump hanger top plate. In most cases, this allows the OEM fuel lines and connections to be-reused. However, aftermarket high-flow -AN lines can also be used by swapping out the fitting adapters (included). Each electrical connection is clearly labeled for quick installation. Wiring terminals are included with the kit.

The fuel hanger kit includes all the hardware, fittings and pieces shown above for a complete installation. It can be purchased pre-assembled with pumps, or without pumps included. As with all Radium Engineering products, this item is compatible with all fuel types including E85.
