OE Sniper EFI Fuel Rail Kit - LS3 Intakes

The OE Sniper EFI Fuel Rail Kit - LS3 Intakes is a precision fuel distribution system engineered for GM LS-series engine platforms running electronic fuel injection. Built for enthusiasts and performance shops seeking OEM-quality fuel delivery without compromise, this Holley fuel rail kit integrates seamlessly into LS3 intake manifolds to provide consistent, regulated fuel supply across all cylinders. Whether you're building a street engine, performance vehicle, or custom application, proper fuel rail architecture ensures optimal EFI tuning and engine responsiveness.

Constructed from lightweight aluminum with black anodized finish, this fuel rail kit features eight AN female O-ring inlets and eight AN female O-ring outlets, allowing flexible fuel line routing and modular fuel system configuration. The anodized coating resists corrosion and oxidation while maintaining a clean, professional appearance in engine bays. Eight outlet ports enable individual fuel injector supply or manifold distribution, giving builders the flexibility to match various intake designs and fuel system architectures without custom fabrication or adapter plates.

This kit is ideal for LS3 intake-equipped engines in street cars, track vehicles, and high-output applications where precision fuel metering directly affects performance and drivability. The eight-port design accommodates both factory LS3 fuel injector counts and modified configurations, making it compatible with stock replacements, turbo builds, and naturally aspirated performance swaps. Installation requires proper fuel line sizing (AN fitting equivalency) and knowledge of fuel system pressure regulation to prevent backpressure issues or lean conditions.
