Upgrade your 06-11 Honda Civic Si with Hybrid Racing's K-Series Fuel Rail & Fittings, engineered for peak performance. These fuel rails are constructed from 6061 aluminum, benefiting from T6 heat treatment for durability. The anodized finish and laser-etched Hybrid Racing logo ensure your engine bay remains stylish while your engine receives a steady fuel supply.

Convenient Fuel Pressure Monitoring

Incorporated into each fuel rail is a 1/8" NPT hole, designed for the direct mounting of a fuel pressure gauge. This feature places the gauge in an easily visible location, simplifying fuel pressure checks without the need to inspect the entire engine bay.

Adaptable Fittings for Custom Fuel Line Setups

Hybrid Racing's fuel rails are versatile, with ports that accept -8 ORB fittings for both the inlet(s) and outlet. This compatibility allows for the use of either -6 or -8 AN fuel lines, catering to a range of fuel system requirements.

Central Fuel Line Routing Option for a Tidier Engine Bay

An outstanding design aspect is the option to redirect the fuel line to a centrally located -8 ORB fitting. This allows for neater routing of the fuel line between the middle two cylinder intake runners, depending on your intake manifold, ideal for those aiming for a wire-tucked engine bay.

Broad Intake Manifold Compatibility

Hybrid Racing's fuel rail is designed to mount seamlessly to the PRB, RBC, and RBB intake manifolds, requiring no modifications. It is also compatible with any aftermarket intake manifolds that share the same mounting points.

Ready for E85 Fuel

These fuel rails are fully compatible with E85, making them suitable for diverse fueling strategies and engine tuning needs.
