Description

ABOUT THIS PRODUCT

The new Hi-Flow billet fuel rails are a direct fit for naturally aspirated Gen III Hemi engines including the 5.7L, 6.1L, and the 6.4L from 2003-2021. The fuel rails feature a 5/8" diameter fuel passage that provides more flow capacity for high horsepower applications over the stock rails.

Product Features:
  • Direct fit for naturally aspirated Gen III Hemi engines including the 5.7L, 6.1L, and the 6.4L engines
  • Machined Billet extrusions with laser etched "Holley EFI" Logo
  • Injector Clip feature retained so factory injector clips can be re-used. This is important as the clips locate the injector radially for proper injector spray pattern onto valves.
  • -8 ORB ports front and back
  • 1/8 NPT gauge ports machined directly into rail
  • Mounting brackets and hardware included
