The Radium Engineering Fuel Rail Plumbing Kit provides the complete post-pump filtration and fuel line solution required when using the Radium Engineering fuel pump hanger on Subaru EJ-platform vehicles. An 8AN PTFE feed line routes from the Radium hanger to a Radium fuel filter mounted under the vehicle, with an 8AN rubber hose continuing to the fuel rails. A 6AN rubber return hose routes fuel from the fuel pressure regulator back to the hanger.
Billet aluminium retainers are included to secure all fuel lines. The filter bracket mounts to the chassis with no drilling or permanent modifications required.
Note: Aftermarket fuel rails and a fuel pressure regulator are recommended.
