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. The black anodized rails have -8 ORB ports on each end and an 1/8" NPT port for a fuel gauge installation if you choose to do so. The rails are designed with the factory injector clip reliefs so that your factory injectors and retaining clips can be reused. The kit includes fuel rails, mounting brackets and required mounting hardware.

Features:
