Product Details

Upgrade your Honda or Acura K-Series fuel system with the Skunk2 Racing K-Series Ultra Fuel Rail (350-05-7000). Engineered for high-performance naturally aspirated, turbocharged, and supercharged applications, this premium fuel rail delivers the flow capacity, durability, and versatility needed for demanding engine builds.

Designed specifically for Skunk2's Ultra Street and Ultra Race intake manifolds, this fuel rail features a large 17mm (0.669-inch) internal bore to accommodate high fuel-flow demands. Its CNC-machined billet aluminum construction provides strength and precision, while the corrosion-resistant hard-anodized finish makes it suitable for a variety of racing and performance fuels.

One of the biggest advantages of the 350-05-7000 is its versatile design. The same fuel rail can be used in either the primary or secondary injector position on compatible Skunk2 Ultra Race intake manifolds, eliminating the need for separate fuel rail designs.

With a manufacturer-advertised capability of supporting 1,200+ horsepower, this fuel rail is an excellent choice for serious K20, K24, and K20/K24 Frankenstein engine builds.

Common Reasons for Replacement or Upgrade

High-Horsepower Engine Builds: Upgrading the fuel system to support increased fuel demand from turbochargers, superchargers, or aggressive naturally aspirated setups.
Skunk2 Intake Manifold Installation: Installing an Ultra Street or Ultra Race intake manifold that requires the appropriate fuel rail.
Secondary Injector Conversion: Adding a second set of injectors to a compatible Ultra Race intake manifold for increased fuel delivery.
Fuel System Modernization: Replacing an older fuel rail with a versatile design that supports custom fuel line configurations.
Damaged or Corroded Fuel Rail: Replacing a compromised fuel rail to maintain safe and reliable fuel delivery.
Custom Fuel System Plumbing: Building a performance fuel system using appropriately sized fittings, fuel lines, regulators, and injectors.

Installation Notes

Verify Intake Manifold Compatibility: Confirm that your Skunk2 Ultra Street or Ultra Race intake manifold supports fuel rail part number 350-05-7000.
Relieve Fuel System Pressure: Before removing any fuel system components, safely relieve residual fuel pressure according to the vehicle manufacturer's service procedures.
Inspect Fuel Injectors and Seals: Verify injector fitment and inspect all injector O-rings and sealing surfaces. Replace damaged or worn seals before installation.
Install the Fuel Rail: Position the rail in the correct primary or secondary mounting location using the appropriate mounting hardware and injector configuration.
Select Proper Fuel Fittings: Use compatible -8 ORB adapters with the correct O-rings. Do not attempt to install standard -8 AN flare fittings directly into the ORB ports.
Connect Fuel Lines: Route fuel lines away from exhaust components, moving engine parts, and sharp edges. Use fuel-compatible hoses and fittings rated for the intended operating pressure.
Verify Fuel System Configuration: Confirm that the fuel pump, injectors, fuel pressure regulator, and associated plumbing are appropriately sized for the engine's power requirements.
Check for Fuel Leaks: Prime and pressurize the fuel system, then carefully inspect all fittings, injector seals, and connections before starting the engine.
Verify ECU Calibration: Any changes to injector size, fuel pressure, or fuel system operation must be addressed through appropriate ECU calibration and professional tuning.
Professional installation is recommended, particularly for custom high-pressure fuel systems and multi-injector configurations.
