Radium Fuel Rail Plumbing Kit w/Filter - Subaru WRX 08-14/STI 08-21/FXT 08-13/LGT 04-09

Application: 2008-2021 Subaru Impreza / WRX / WRX STI / Forester with the Radium Late Model Subaru fuel pump hanger
Part Type: Fuel hanger plumbing kit with high-flow fuel filter
Part Number: 20-0629-03, 20-0629-05


The Radium Fuel Hanger Plumbing Kit adds the post-pump filtration needed when running the Radium Late Model Subaru fuel pump hanger. The hanger does not use an internal filter, so an external filter is required.

An 8AN PTFE feed line runs from the hanger to a Radium high-flow filter mounted under the car, then an 8AN rubber hose continues to the fuel rails. A 6AN rubber hose returns fuel from the regulator to the hanger. Billet aluminium retainers secure the lines and the filter bracket mounts to the chassis with no drilling or permanent modifications.

  • Post-Pump Filtration: Radium high-flow fuel filter included
  • 8AN Feed: PTFE line from hanger to filter, rubber hose from filter to rails

  • No Drilling: Filter bracket mounts to the chassis without permanent modifications
