Radium Engineering's drop-in fuel pump hanger replaces the factory in-tank unit on late model Subaru vehicles and runs one or two DeatschWerks DW400 pumps. An anodized aluminum collector box with two one-way fill valves (355 LPH each) and a venturi jet pump with integrated pressure relief keeps the pumps fed, and a duckbill valve sits on the return path. Outlets are an 8AN ORB pump feed plus 6AN ORB return and crossover ports with SAE quick connect adapters preinstalled. It reuses the OEM gasket and factory fuel level sensor, and all components are safe with E85. Pumps are not included.
