Product Overview
Hybrid Racing K-Series Fuel Rail – Honda Civic EP3 & Integra DC5
Take your Honda K-Series engine build to the next level with the Hybrid Racing K-Series Fuel Rail & Fittings, a premium fuel system upgrade developed for performance enthusiasts.
Designed for compatible Honda Civic Type R EP3 and Integra Type R DC5 applications, this high-quality aluminium fuel rail offers versatile fuel-line routing, useful pressure-monitoring options and a distinctive motorsport-inspired appearance.
Whether you’re refreshing your K20 engine bay, upgrading your fuel system or planning a more extensive naturally aspirated or forced-induction build, the Hybrid Racing fuel rail offers a practical foundation for a carefully matched fuel delivery system.
Precision-Engineered 6061-T6 Aluminium Construction
The Hybrid Racing K-Series fuel rail is manufactured from high-quality 6061 aluminium with T6 heat treatment.
Its precision-machined construction provides strength and durability, while the anodised surface helps protect the rail and gives it a premium finish.
Choose between two attractive colours:
- Dust Black (HYB-FRL-01-16): A discreet finish suited to OEM-plus and stealth engine bay builds.
- Dust Red (HYB-FRL-01-17): A bold finish that complements performance-focused and show-quality engine bays.
Both versions feature laser-etched Hybrid Racing branding.
Flexible Fuel-Line Routing and Centre-Feed Design
One of the standout features of this Hybrid Racing fuel rail is its flexible fuel-line configuration.
The rail incorporates -8 ORB ports that can accommodate suitable fittings for -6 AN or -8 AN fuel-line arrangements.
Its centrally positioned fuel port provides an alternative to conventional end-fed fuel-line routing.
When used with a suitable intake manifold and fuel-line configuration, this centre-feed arrangement allows a cleaner installation with reduced visible fuel plumbing.
This makes the fuel rail particularly attractive for Honda enthusiasts building a clean or tucked K-Series engine bay.
Integrated Fuel Pressure Gauge Port
Fuel pressure monitoring is an important consideration for modified Honda engines.
The Hybrid Racing K-Series fuel rail includes a dedicated 1/8″ NPT port that accepts a compatible fuel pressure gauge or appropriately specified sensor fitting.
Positioning the gauge directly on the fuel rail can provide convenient access when checking fuel pressure during inspection, tuning or maintenance.
Please note: A fuel pressure gauge is not included.
Compatible with Popular Honda K-Series Intake Manifolds
The fuel rail has been confirmed compatible with the following intake manifold mounting arrangements:
- Honda PRB intake manifold
- Honda RBC intake manifold
- Honda RBB intake manifold
- Compatible aftermarket manifolds sharing these mounting positions
This versatility makes it suitable for selected K20 and K24 installations, provided that injector, manifold, fuel-line and mounting compatibility are confirmed.
Suitable for Different Performance Builds
The Hybrid Racing fuel rail can be incorporated into appropriately designed fuel systems for:
- Naturally aspirated Honda K20 engines
- Turbocharged K-Series projects
- Supercharged K-Series builds
- Honda K-Series engine swaps
- Road and track-day performance vehicles
The fuel rail is E85 compatible.
Correct fuel injectors, pump capacity, pressure regulation and tuning are still required for the intended application. The fuel rail alone does not guarantee additional horsepower.
