The new Hi-Flow billet fuel rails are a direct fit for all late model, 2011 and newer naturally aspirated Coyote engines (5.0 and 5.2) including Cobra Jet and Boss 302. This also includes the 2018 and newer direct injection engines. The fuel rails feature a 5/8" diameter fuel passage that provides the flow capacity for high horsepower applications. 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.
