Mitsubishi Evolution X Fuel Pump Hangers for Walbro GSS342 and AEM 50-1000/1200 Fuel Pumps by Radium Engineering

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 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.
