Radium Engineering Fuel Rail Plumbing Kit Parallel Style | Subaru WRX, STI, All EJ Series

Description

These plumbing kits are designed to complement Radium Engineering Subaru EJ fuel rail installations. Both kits interface with the factory feed and return hard lines in the engine bay (near the LH strut tower) and provide all the underhood fuel plumbing. Both kits are compatible with all Radium Fuel Rails for the Subaru EJ engines (excluding the 20-0499 Dual Injector Fuel Rails). All necessary fittings and hoses are included, along with an adjustable Radium Engineering fuel pressure regulator.

Tool-less Pressure Adjustment

All Radium Engineering regulators feature the first tool-less pressure adjustment. A jam nut and set screw are no longer required. With a simple turn of the knob, pressure will be increased or decreased.

Kit Configurations

Two plumbing kits are offered; one that feeds the fuel rails in series, and another that feeds the fuel rails in a parallel configuration. Both kits perform equally well. The end decision is based on personal preference.

Important Notes

• Neither kit includes a fuel filter.
• Neither kit is compatible with Radium dual port injector fuel rail kit 20-0499.
• Both kits are safe to use with alcohol fuels such as methanol, ethanol, E85, etc.
• Both kits use 3/8" (6AN) high pressure EFI fuel hose.
• Both kits include 8AN ORB plugs for the fuel rails. Use these plugs if fuel pulse dampers are not being used.
