Hybrid Racing K-Swap fuel rails are made from 6061 aluminum with T6 heat treatment—and feature a durable anodized finish with a laser-etched logo, ensuring that your engine bay looks fresh and your engine stays fed! Each rail includes a 1/8 in. NPT hole that allows you to mount a fuel pressure gauge directly to your fuel rail. This puts the fuel pressure gauge in a spot that's easily visible, so you don't have to poke around in the engine bay just to see if you have fuel pressure. All of the ports can accept a -8 ORB fitting in the inlet(s) and outlet, enabling you to run either -6 or -8 AN fuel lines. The other detail that should stand out is the option for plugging the side inlet and outlet to allow you to run your fuel line to a centrally located -8 ORB fitting. This is positioned so that the fuel line can pass between the middle two cylinder intake runners (depending on your intake manifold.) This is an excellent option for anyone looking to tuck their wires and lines. Additional notes: * These rails have been shown to mount to the PRB, RBC, and RBB intake manifolds without needing any modifications. Any aftermarket intake manifolds that share the same fuel rail mounting points as the PRB, RBC, or RBB should also accept this rail. * Available with a Dust Red or Dust Black finish * E85 compatible * What's included: -- (1) K-Series fuel rail -- (2) -8 ORB / -6 AN adapter fitting -- (2) -8 ORB plug -- (1) 1/8th NPT plug
