Optional Plumbing Kit     Part# 20-0478

This engine bay plumbing kit is designed to be used with all Radium EJ fuel rails and includes all the necessary fittings, hose and other components to complete the installation and have a complete operating system. This kit plumbs the fuel rails in series, beginning and ending at the factory hard lines near the LH strut tower.  It is compatible with all factory hard lines, whether SAE quick connect or hose barb connections. An adjustable Radium Direct Mount Regulator (DMR) is included along with a Radium fuel pressure gauge to calibrate the DMR. The 6AN swivel adapter fittings for the fuel rail ports are low profile making them ideal for the tight spaces associated with the EJ motor. Pushlock hose-ends are easy to work with, making installation quick and painless. A variety of hose-ends are provided so the installer can custom tailor the fuel line routing for their specific vehicle. A parallel feed system is not possible with this kit.

The fuel hose included in this kit can be cut and installed with standard tools and without special skills. Unlike standard low-quality rubber fuel hose that degrades with alternate fuels, the provided Vapor Shield hose is resistant to all fuels including E85. Furthermore, the hose has a thermoplastic armor layer that guards against unwanted vapor permeation (gas smell). And unlike PTFE, this fuel hose helps absorb absorbs unwanted fuel injector pulses and has an easy to work with bend radius.

Included in Optional Plumbing Kit

  • Direct Mount Regulator
  • 6AN PushLok Hose Ends
  • 6AN Adapter Fittings
  • SAE Quick Connect Fittings
  • 3/8" ID Vapor Shield EFI Hose
  • Stainless EFI Hose Clamps
