Application: Subaru Impreza / WRX / STI, Forester, Legacy and Outback – see Vehicle Fitment
Part Type: Fuel pump hanger (single or dual pump)
Part Number: 20-0780-00, 20-0781-00, 20-0782-00

The Radium Late Model Subaru Fuel Pump Hanger replaces the OEM hanger and fuel hold-down flange (reusing the OEM gasket) and supports one or two high-flow aftermarket fuel pumps. It is safe with E85 and other alternative fuels and requires no permanent modifications.

An anodised aluminium collector box keeps fuel around the pumps to help prevent starvation, fed by two one-way fill valves and a venturi jet pump with an integrated pressure relief valve that moves fuel from the passive to the active side of the tank without restricting the return. Each pump merges internally into a single outlet, so no external line merging is needed.

Key Features

• Single or Dual Pump: Supports one or two high-flow aftermarket pumps
• Collector Box: Anodised aluminium, with two 355 LPH one-way fill valves (710 LPH total)
• PRV Jet Pump: Venturi jet pump with integrated pressure relief valve transfers fuel without restricting the return
• Duckbill Valve: One-way valve prevents backflow and reduces fuel spray noise
• Merged Outlet: 8AN ORB (3/4"-16) pump-out port with preinstalled SAE quick connect male fitting
