Radium Engineering Fuel Pump Hanger Subaru WRX / STI (GR / GV / VA)

Radium Engineering Fuel Pump Hanger - Subaru WRX / STI (GR / GV / VA)

The Radium Engineering in-tank fuel pump hanger replaces the OEM fuel pump module on later Subarus including the Impreza WRX and STI (GR/GV) and WRX / STI (VA), running one or two high-flow aftermarket pumps. The CNC machined, anodised assembly uses the factory gasket, replaces the OEM hold-down flange and needs no permanent modifications.

2015 STI FUEL SYSTEM UPGRADE! Radium Hanger + Walbro 450 Install 🔥⛽

An anodised aluminium collector box traps fuel around the pumps, with two 355LPH one-way fill valves (710LPH total) and a venturi jet pump with integrated pressure relief that scavenges the passive side of the tank without restricting the return. Pump outputs merge internally to an 8AN ORB feed port, with 6AN ORB return and crossover ports, each fitted with an SAE quick connect adapter for the OEM lines. Use the variant selector to match your pumps: 20-0780-00 for Walbro GSS342 / AEM 50-1200, or 20-0782-00 for Walbro F90000267/274/285.

Note: Fuel pumps are sold separately. An external fuel pressure regulator is required, and the OEM post-pump fuel filter is eliminated – Radium plumbing kits include a replacement. Forester XT and 2015–2021 WRX require Radium 20-0850 fuel level sender adapter. Upgraded pump wiring is recommended. Installation by a professional is recommended.
