Radium Fuel Rail Kits suit Subaru EJ20/25

Description
Radium Engineering to offer an exciting new fuel plumbing option for Subaru owners upgrading to aftermarket fuel rails. These kits offer quality nylon-braided PTFE fuel hose with a range of Billet fittings to plumb your new parallel fuel rail kit.

PTFE Hose

PTFE is the ultimate hose material. It has outstanding resistance to chemicals including alcohol fuels such as methanol, ethanol, E85 and leaded fuels such as race gas. It is also suitable for brake, transmission, clutch, power steering, and coolant. PTFE hose has ~zero~ permeation and will not emit vapors like rubber fuel hose, so it is safe to use in confined spaces such as a vehicle’s trunk or small garage.

All Radium Engineering PTFE hoses have been successfully tested in-house to 1200psi although PTFE can typically withstand 2500psi+. They are also for extreme temperatures (-94F to +480F). They feature an extruded PTFE (fluoropolymer) core wrapped in a stainless steel wire braided sleeve. The outer coating is determined by the assembly process: Universal DIY ends (braided PET) or preassembled crimped ends (smooth PVC). All hose ends are type-II black anodized aluminum. 

PTFE Hose Ends

These hose ends are specific to PTFE hose and cannot be used with rubber hose. Each fitting is machined from aluminum and anodized black. Internal O-rings permit swivelling.

The following vehicles can use the plumbing kit, however the fuel feed and fuel return lines do not utilise the SAE EFI Quick Connect style fittings. For vehicles without this SAE fitting additional parts will be required to convert the OEM hard fuel lines to AN-6 male flares. In addition, these vehicles utilise a fuel filter located in the engine bay which will not be suitable with this plumbing kit and an aftermarket filter will need to be purchased separately.
