Upgrade your 01-05 Honda Civic Si or 02-06 Acura RSX with Hybrid Racing's K-Series Fuel Rail & Fittings. Crafted from 6061 aluminum and treated with T6 heat, these fuel rails boast a durable anodized finish, complete with a laser-etched Hybrid Racing logo. Not only will your engine bay look immaculate, but your engine's fuel needs will also be efficiently met.

Convenient Fuel Pressure Monitoring

Each fuel rail features a 1/8" NPT hole, allowing for the direct mounting of a fuel pressure gauge. This design places the gauge in a highly visible location, eliminating the need to search through the engine bay to verify fuel pressure.

Versatile Fitting Options for Custom Setups

Hybrid Racing's fuel rails offer flexibility with ports that can accept -8 ORB fittings, catering to either -6 or -8 AN fuel lines. This adaptability is perfect for custom fuel line setups, ensuring compatibility with various performance needs.

Centralized Fuel Line Option for a Clean Look

An innovative design feature is the option to plug the side inlet and outlet, routing your fuel line to a centrally located -8 ORB fitting. This allows the fuel line to pass neatly between the middle two cylinder intake runners, depending on your intake manifold. This setup is ideal for those aiming for a wire-tucked and streamlined engine bay.

Compatibility with Popular Intake Manifolds

Hybrid Racing's fuel rail is designed to mount effortlessly to PRB, RBC, and RBB intake manifolds without any modifications. It's also compatible with aftermarket intake manifolds sharing the same fuel rail mounting points.

Ready for E85 Applications

This fuel rail is fully compatible with E85, offering versatility for different fuel types and ensuring reliable performance for diverse engine tuning needs.
