Hybrid Racing Fuel Rail for 02-06 RSX/EP3/12-15 Civic Si

Hybrid Racing Fuel Rail - DC5/EP3/9th Gen Civic Si

Designed to maximize fuel delivery for K-series builds, the Hybrid Racing fuel rail for 02-06 RSX, EP3 Civic Si, and 12-15 Civic Si is machined from a solid billet of 6061-T6 aluminum. This race-bred rail delivers unrestricted, uniform fuel flow to the K20/K24 while adding a clean, motorsport appearance to the engine bay thanks to its corrosion-resistant anodized finish and laser-etched Hybrid Racing logo. Color options are Dust Black or Dust Red to suit customer builds.

Why it outflows the rest

• Full-bore design – oversized internal bore and -8 ORB ports prevent pressure drop at high RPM, whether running -6 or -8 AN lines.
• Central or side feed – block off the side ports and route a single feed to the center for a neatly tucked line between the middle runners.
• Gauge-ready – factory-machined 1/8" NPT port lets your customers bolt on a fuel-pressure gauge exactly where visibility is highest.
• E85 proof – Viton O-rings and anodized barrier stand up to today’s aggressive ethanol blends.
• Bolt-on fit – mounts directly to OEM PRB, RBC, and RBB intake manifolds (and any aftermarket manifold that copies those bosses) with stock injectors or popular aftermarket units.

Built for builders

Each rail ships with stainless M8 mounting hardware and port plugs, enabling line routing choices without extra trips to the parts store. When paired with Hybrid Racing’s line kits, these rails support a zero-leak, show-ready install.

Dealer-focused notes

• Resale relevance: Aligns with customer demand for reliable high-flow fuel delivery during performance builds on K-series platforms, including ethanol-compatible setups.
• When to recommend: Use for installs where maintaining consistent fuel delivery at elevated RPM is important, when employing central or single-feed routing, or when a gauge port is desirable for ongoing tuning verification.
• Stocking rationale: Broad compatibility with OEM and aftermarket manifolds that copy the PRB/RBC/RBB bosses supports a wide range of builds and installer preferences.
