Description
The Radium fuel pump hanger allows the use of 1 or 2 aftermarket pumps.
The machined assembly mounts in the factory fuel tank using the OEM gasket and hardware. The fuel level sender and temperature sensors are retained, as shown below. The pumps merge into a single port outlet with 8AN ORB threads. The crossover and return uses 6AN ORB threaded ports. To simplify plumbing, the kit includes OEM hose adapter fittings for all model years listed. Shown below is the configuration for older models which use all barbs.
Shown below is for mid model years which use a SAE quick disconnect fuel feed. There is also a return line SAE quick disconnect fitting included for newer models. Lastly, -6AN male fittings are included for those that use aftermarket feed and return hoses.
Wire connections are done with specially designed stainless steel studs. As shown, all in-tank wiring is high quality PTFE insulated for use in gasoline and ethanol. Stainless steel crimp-on ring terminals and heat shrink are provided for external wiring connections.
The kit includes a Radium venturi jet pump with interchangeable orifices that is optimized for high flow pump(s). The kit also includes a streamlined anodized aluminium collector box.
Unlike the 2004-2007 WRX STi OEM variation, the Radium Engineering collector box has been optimized to work in ALL gas tanks. Shown below is the smallest OEM gas tank baffle found in the model list above. It improves the fuel supply around the pump(s) inlet. There is a 1″ check valve incorporated on the front side of the tank that serves as a trap door 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 OEM fuel level and fuel temperature sensors secure to the mounting bracket.
Single pump applications can reuse the OEM fuel pump controller, but it is recommended to upgrade the wiring as high flow fuel pumps draw additional current requiring larger gauge wire.
