Radium Engineering Engines Fuel Rail Plumbing Parallel Subaru EJ
Two kits are offered; one that feeds the fuel rails in series, and another that feed the fuel rails in a parallel configuration. Both kits perform equally well. The end decision is based on personal preference. Scroll down for details on each kit.
RA-series 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.
Both kits are compatible with all Radium Fuel Rails for the Subaru EJ engines (excluding 20-0499 Fuel Rails). compatible.
IMPORTANT NOTES:
1. Neither kit includes a fuel filter.
2. Neither kit is compatible with Radium dual port injector fuel rail kit 20-0499.
3. Both kits are safe to use with alcohol fuels such as methanol, ethanol, E85 etc.
4. Both kits use 3/8" (6AN) high pressure EFI fuel hose.
Because of the regulator mounting location and OEM fuel filter placement, the parallel fuel rail plumbing kit is only compatible with the 2005+ Impreza (WRX/STi) and Forester platform.
