Subaru FA20F vehicles use a returnless fuel system with a different OEM fuel unit, so the fuel level float is also unique. The Radium 20-0850 provides the correct mount for the OEM fuel level sensor on Radium's late-model Subaru fuel pump hanger.
A stainless cover plate is included to block the unused holes on the hanger's collector box. The adaptor is required when fitting the Radium hanger to the FA20F WRX and Forester XT.
