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

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

Turn every ounce of K-series potential into forward motion with the Hybrid Racing fuel rail for 02-06 RSX, EP3 Civic Si, and 12-15 Civic Si. Machined from a solid billet of 6061-T6 aluminum, this race-bred rail delivers unrestricted, uniform fuel flow to your K20/K24 while adding a clean, motorsport look to the bay thanks to its corrosion-proof anodized Dust Black or Dust Red finish and laser-etched Hybrid Racing logo.

Why it outflows the rest

• Full-bore design – oversized internal bore and ­-8 ORB ports prevent pressure drop at high RPM, whether you run ­-6 or ­-8 AN lines.
• Central or side feed – block off the side ports and route your single feed to the center for a perfectly tucked line between the middle runners.
• Gauge-ready – factory-machined 1/8" NPT port lets you bolt on a fuel-pressure gauge exactly where you can see it.
• 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

Every rail ships with stainless M8 mounting hardware and port plugs, so you choose your line routing without extra trips to the parts store. Pair it with Hybrid Racing’s line kits for a zero-leak, show-ready install.
