The Hybrid Racing K-Series Swap Standard Fuel System Package takes the guesswork out of one of the most important parts of any K-swap by combining every major fuel system component into a single, engineered package. Designed specifically for 1992-2000 Honda Civics, 1994-2001 Acura Integras, and 1993-1997 Honda Del Sols with K-series engine conversions, the kit converts the factory returnless K-series fuel setup into the return-style system these chassis require. It includes a pre-assembled, pressure-tested fuel line kit, a billet 6061-T6 aluminum fuel rail, an adjustable fuel pressure regulator with all required fittings and mounting hardware, and a 0-100 psi fuel pressure gauge for accurate setup. Every component is E85 compatible, and the pre-configured fittings eliminate the trial-and-error of sourcing individual parts. Whether you're completing your first K-swap or refreshing an existing build, this package delivers a clean installation, reliable fuel delivery, and the confidence that every component is designed to work together from day one.
Standard Fuel Line Kit (uses oem fuel filter)
Tucked Fuel Line Kit (uses inline filter)
The Hybrid Racing K-Swap Tucked Fuel Line Kit is designed for builders who want the cleanest possible engine bay without sacrificing reliability. Instead of routing the fuel line across the top of the engine, the tucked design passes between the second and third intake runners before hugging the transmission case on its way to the fuel pressure regulator, keeping the plumbing almost completely out of sight. The pre-assembled, pressure-tested kit converts your K-swap to the required return-style fuel system while eliminating the bulky OEM fuel filter and simplifying installation. Featuring E85-compatible -6AN feed and -4AN return lines, a 100-micron inline fuel filter, and compatibility with the Hybrid Racing center-feed fuel rail and most aftermarket center-feed rails, the tucked fuel line kit delivers both a cleaner appearance and dependable fuel delivery for any EG, EK, or DC K-series swap.

The Hybrid Racing Universal K-Series Fuel Rail is engineered to deliver consistent fuel distribution while offering the flexibility needed for everything from stock-replacement builds to high-horsepower race applications. Precision-machined from a solid billet of 6061 aluminum, the rail features a large internal bore to support increased fuel volume and is compatible with all OEM K-series intake manifolds as well as most aftermarket manifold designs. The center-feed configuration promotes even fuel delivery across all four injectors, while -8 ORB ports on each end allow builders to configure the fuel system for deadhead or return-style plumbing with a wide range of AN fittings. Available in multiple anodized finishes and designed to accept OEM-style injectors, the Hybrid Racing fuel rail is a durable, versatile upgrade that combines OEM fitment with the flow capacity and customization required for serious performance builds.
Universal Fuel Pressure Regulator
The Hybrid Racing Fuel Pressure Regulator gives K-series builders precise control over fuel pressure while maintaining stable fuel delivery under every driving condition. The CNC-machined billet aluminum body is designed for long-term durability and features ORB ports for flexible AN plumbing, making it easy to integrate into custom return-style fuel systems. Whether you're fine-tuning a race car or completing a reliable street K-swap, the Hybrid Racing fuel pressure regulator offers OEM-level reliability with the adjustability and performance modern engine builds demand.
The Hybrid Racing Fuel Pressure Gauge provides a quick and accurate way to verify fuel system pressure during installation, troubleshooting, or routine maintenance. Featuring a 0–100 psi range, the liquid-filled gauge delivers stable, easy-to-read measurements while minimizing needle vibration caused by engine or fuel system pulsations. Its compact design threads directly into the fuel pressure regulator or other compatible 1/8-inch NPT ports, making it simple to confirm base fuel pressure before tuning or diagnosing fuel delivery issues. Whether you're setting up a fresh K-swap or chasing a performance issue, the Hybrid Racing fuel pressure gauge is an inexpensive but essential tool that helps ensure your fuel system is operating exactly as intended.
EG/DC/EK High Volume Fuel Pump (E85 safe)
The Hybrid Racing High-Flow Fuel Pump is a direct-fit upgrade for 1992-2000 Honda Civics and 1994-2001 Acura Integras, delivering the additional fuel volume needed to support naturally aspirated and forced induction K-series swaps. Designed as a drop-in replacement for the factory in-tank pump, it provides reliable fuel delivery at higher horsepower levels without requiring extensive modifications to the fuel tank or pump assembly. The pump is compatible with both gasoline and ethanol-blended fuels, making it a great choice for modern street and race builds alike. Whether you're replacing an aging OEM pump or building a fuel system capable of supporting future power upgrades, the Hybrid Racing high-flow fuel pump offers dependable performance, straightforward installation, and the flow capacity needed to keep your engine supplied under demanding conditions.
